Wikipedia:Manual of Style

This Manual of Style (MoS or MOS) is the style manual for all English Wikipedia articles (though provisions related to accessibility apply across the entire project, not just to articles). This primary page is supported by further detail pages, which are cross-referenced here and listed at Manual of Style/Contents. If any contradiction arises, this page has precedence.

Editors should write articles using straightforward, succinct, easily understood language and structure articles with consistent, reader-friendly layouts and formatting (which are detailed in this guide).

Where more than one style or format is acceptable under the MoS, one should be used consistently within an article and should not be changed without good reason. Edit warring over stylistic choices is unacceptable.

New content added to this page should directly address a persistently recurring style issue.

Retaining existing styles
Sometimes the MoS provides more than one acceptable style or gives no specific guidance. When either of two styles is acceptable it is generally considered inappropriate for a Wikipedia editor to change from one style to another unless there is some substantial reason for the change.

Edit-warring over style, or enforcing optional style in a bot-like fashion without prior consensus, is never acceptable.

Unjustified changes from one acceptable, consistently applied style in an article to a different style may generally be reverted. Seek opportunities for commonality to avoid disputes over style.

If you believe an alternative style would be more appropriate for a particular article, seek consensus by discussing this at the article's talk page or – if it raises an issue of more general application or with the MoS itself – at Wikipedia talk:Manual of Style. If a discussion does not result in consensus for the change at the article, continue to use the already-established style there. If discussion fails to reach a consensus regarding which of two or more competing styles to use at all, then default to the style that was used in the first post-stub version of the article in which one of the applicable styles appeared. (This fall-back position does not give unchallengable primacy to that particular style during consensus discussion, nor give the editor who imposed that earliest style any more say in the discussion.)

Article titles
A title should be a recognizable name or description of the topic, balancing the criteria of being natural, sufficiently precise, concise, and consistent with those of related articles.

For formatting guidance see the section, noting the following:
 * Capitalize the initial letter (except in rare cases, such as eBay), but otherwise follow sentence case (Funding of UNESCO projects), not title case (Funding of UNESCO Projects), except where title case would be used in ordinary prose. See Naming conventions (capitalization).
 * To italicize, add near the top of the article. For mixed situations, use, e.g., , instead. Use of italics should conform to.
 * Do not use articles (a, an, or the) as the first word (Economy of the Second Empire, not The economy of the Second Empire), unless it is an inseparable part of a name (The Hague) or title of a work (A Clockwork Orange, The Simpsons).
 * Normally use nouns or noun phrases: Early life, not In early life.
 * The final character should not be punctuation unless it is an inseparable part of a name (Saint-Louis-du-Ha! Ha!, Do Androids Dream of Electric Sheep?) or an abbreviation (Inverness City F.C.), or when a closing round bracket or quotation mark is required (John Palmer (1814 schooner)).
 * Whenever quotation marks or apostrophes appear, add a redirect for the same title using apostrophes.

Subject both to the above and to Article titles, the rest of the MoS, particularly, applies also to the title.

Section organization
An article's content should begin with an introductory – a concise summary of the article – which is never divided into sections. The remainder of the article is typically divided into sections.

Infoboxes, images, and related content in the lead section must be right-aligned.

Certain standardized templates and wikicode that are not sections go at the very top of the article, before the content of the lead section, and in the following order:
 * A short description, with the template
 * A disambiguation hatnote, most of the time with the template
 * No-output templates that indicate the article's established date format and English-language variety, if any (e.g.,, )
 * Banner-type maintenance templates, Dispute and Cleanup templates for article-wide issues that have been flagged (otherwise used at the top of a specific section, after any sectional hatnote such as )
 * An infobox, which is optional (except in special cases like and, or a variant thereof, at applicable articles); usually also includes the first image
 * An introductory image, when an infobox is not used, or an additional image is desired for the lead section (for unusually long leads, a second image can be placed midway through the lead text)

In the Vector 2022 skin, the table of contents is separate from the article content. In some older skins, a navigable table of contents appears automatically just after the lead if an article has at least four section headings.

If the topic of a section is covered in more detail in a dedicated article, insert or  immediately under the section heading.

As explained in detail in, several kinds of material (mostly optional) may appear after the main body of the article, in the following order:
 * Books or other works created by the subject of the article, under a section heading "Works", "Publications", "Discography", "Filmography", etc. as appropriate (avoid "Bibliography", confusable with reference citations)
 * Internal links to related English Wikipedia articles, with section heading "See also"
 * Notes and references, with a section heading "Notes" or "References" (usually the latter), or a separate section for each in this order ; avoid "Bibliography", confusable with the subject's works
 * Relevant books, articles, or other publications that have not been used as sources; use the section heading "Further reading"; be highly selective, as Wikipedia is not a bibliographic directory
 * Relevant and appropriate websites that have not been used as sources and do not appear in the earlier appendices, using the heading "External links", which may be made a subsection of "Further reading" (or such links can be integrated directly into the "Further reading" list instead); link templates for sister-project content also usually go at the top of this section when it is present (otherwise in the last section on the page)
 * The following final items never take section headings:
 * Internal links organized into navigational boxes
 * Authority control metadata, if needed, using (distinguishes uses of the same name for two subjects, or multiple names for one subject)
 * Categories, which should be the very last material in the article's source code if there are no stub templates
 * Stub templates, if needed, which should follow the categories

Stand-alone list articles have some additional layout considerations.

Section headings
Section headings should generally follow the guidance for article titles (above), and should be presented in sentence case (Funding of UNESCO projects in developing countries), not title case (Funding of UNESCO Projects in Developing Countries).

The heading must be on its own line, with one blank line just before it; a blank line just after is optional and ignored (but do not use two blank lines, before or after, because that will add unwanted visible space).

For technical reasons, section headings should:
 * Be unique within a page, so that section links lead to the right place.


 * Not contain links, especially where only part of a heading is linked.
 * Not contain images or icons.
 * Not contain  markup.
 * Not contain citations or footnotes.
 * Not misuse description list markup (" ") to create pseudo-headings.
 * Not contain template transclusions.

These technical restrictions are necessary to avoid technical complications and are not subject to override by local consensus.

As a matter of consistent style, section headings should:


 * Not redundantly refer back to the subject of the article, e.g., Early life, not Smith's early life or His early life.
 * Not refer to a higher-level heading, unless doing so is shorter or clearer.
 * Not be numbered or lettered as an outline.
 * Not be phrased as a question, e.g., Languages, not What languages are spoken in Mexico?.
 * Not use color or unusual fonts that might cause accessibility problems.
 * Not be wrapped in markup, which may break their display and cause other accessibility issues.

These are broadly accepted community preferences.

An invisible comment on the same line must be the   markup:

It is more usual practice to put such comments the heading.

Before changing a heading, consider whether you might be breaking existing links to it. If there are many links to the old title, create an anchor with that title to ensure that these still work. Similarly, when linking to a section, leave an invisible comment at the heading of the target section, naming the linking articles, so that if the heading is later altered these can be fixed. For (a combined) example:

which will be saved in the article as:

The advantage of using, or simply inserting the   tags directly, is that when edits are made to the section in the future, the anchor will not be included in page history entries as part of the section name. When  is used directly, that undesirable behavior does occur. Note: if electing to insert the span directly, do not abbreviate it by using a self-closing tag, as in, since in HTML5 that XML-style syntax is valid only for certain tags, such as. See for further discussion.

Heading-like material
The above guidance about sentence case, redundancy, images, and questions also applies to headers of tables (and of table columns and rows). However, table headings can incorporate citations and may begin with, or be, numbers. Unlike page headings, table headers do not automatically generate link anchors. Aside from sentence case in glossaries, the heading advice also applies to the term entries in description lists. If using template-structured glossaries, terms will automatically have link anchors, but will not otherwise. Citations for description-list content go in the term or definition element, as needed.

National varieties of English
National varieties of English (for example, American English or British English) differ in vocabulary (elevator vs. lift), spelling (center vs. centre), and occasionally grammar. Articles such as English plurals and Comparison of American and British English provide information about such differences. The English Wikipedia prefers no national variety over others.

An article's date formatting ( vs. ) is also related to national varieties of English – see MOS:DATEFORMAT and especially MOS:DATETIES and MOS:DATEVAR.

Consistency within articles
The conventions of a particular variety of English should be followed consistently within a given article. Exceptions include:
 * Quotations and titles of works (such as books, films, and music) should be given as they appear in sources. However, there are certain situations where this principle is not followed in order to maintain a level of typographic conformity across the encyclopedia: see.
 * Proper names use the subject's own spelling, e.g., joint project of the United States Department of Defense and the Australian Defence Force; International Labour Organization;
 * For articles about chemistry-related topics, the international standard spellings aluminium, sulfur, caesium (and derivative terms) should be used regardless of the variety of English otherwise employed in the article. See.

Opportunities for commonality
For an international encyclopedia, using vocabulary common to all varieties of English is preferable.
 * Use universally accepted terms rather than those less widely distributed, especially in titles. For example, glasses is preferred to the national varieties spectacles (British English) and eyeglasses (American English); ten million is preferable to one crore (Indian English).
 * If a variant spelling appears in a title, make a redirect page to accommodate the others, as with artefact and artifact, so that all variants can be used in searches and linking.
 * Terms that differ between varieties of English, or that have divergent meanings, may be glossed to prevent confusion, for example, the trunk (American English) or boot (British English) of a car ....
 * Use a commonly understood word or phrase in preference to one that has a different meaning because of national differences (rather than alternate, use alternative or alternating, as appropriate), except in technical contexts where such substitution would be inappropriate (alternate leaves; alternate law).
 * When more than one variant spelling exists within a national variety of English, the most commonly used current variant should usually be preferred, except where the less common spelling has a specific usage in a specialized context, e.g., connexion in Methodist connexionalism.

Strong national ties to a topic
An article on a topic that has strong ties to a particular English-speaking nation should use the (formal, not colloquial) English of that nation. For example:

• Afrikaners (South African English)

• American Civil War (American English)

• Australian Defence Force (Australian English)

• Christchurch (New Zealand English)

• Dublin (Hiberno-English)

• Great Fire of London (British English)

• Lagos (Nigerian English)

• Muhammad Ali Jinnah (Pakistani English)

• Mumbai (Indian English)

• Vancouver (Canadian English)

• Wanchai Tower (Hong Kong English)

For topics with strong ties to Commonwealth of Nations countries and other former British territories, use Commonwealth English orthography, largely indistinguishable from British English in encyclopedic writing (excepting Canada, which uses a different orthography).

Retaining the existing variety
When an English variety's consistent usage has been established in an article, maintain it in the absence of consensus to the contrary. With few exceptions (e.g., when a topic has strong national ties or the change reduces ambiguity), there is no valid reason for changing from one acceptable option to another.

When no English variety has been established and discussion does not resolve the issue, use the variety found in the first post-stub revision that introduced an identifiable variety. The established variety in a given article can be documented by placing the appropriate variety of English template on its talk page.

An article should not be edited or renamed simply to switch from one variety of English to another. may be placed on an editor's talk page to explain this.

Capital letters
Wikipedia article titles and section headings use sentence case, not title case; see Article titles and. For capitalization of list items, see. Other points concerning capitalization are summarized below. Full information can be found at Manual of Style/Capital letters. The central point is that Wikipedia does not capitalize something unless it is consistently capitalized in a substantial majority of independent, reliable sources.

Capitalization of The
Generally, do not capitalize the word the in mid-sentence: throughout the United Kingdom, not throughout The United Kingdom. Conventional exceptions include certain proper names (he visited The Hague) and most titles of creative works (Tolkien wrote The Lord of the Rings – but be aware that the may not be part of the title itself, e.g., Homer composed the Odyssey).

There are special considerations for: band names &middot; institution names &middot; nicknames &middot; titles of works &middot; trademarks.

Titles of works
The English-language titles of compositions (books and other print works, songs and other audio works, films and other visual media works, paintings and other artworks, etc.) are given in, in which every word is given an initial capital except for certain less important words (as detailed at ). The first and last words in an English-language title are always capitalized.
 * An Eye for an Eye
 * Worth the Fighting For

Capitalization in foreign-language titles varies, even over time within the same language; generally, retain the style of the original for modern works, and follow the usage in current English-language reliable sources for historical works. When written in the Latin alphabet, many of these items should also be in italics, or enclosed in quotation marks.
 * Les Liaisons dangereuses
 * "Hymnus an den heiligen Geist"

Titles of people

 * In generic use, use lower case for words such as president, king, and emperor (De Gaulle was a French president; Louis XVI was a French king; Three prime ministers attended the conference).
 * Directly before the person's name, such words begin with a capital letter (President Obama, not president Obama). Standard or commonly used names of an office are treated as proper names (David Cameron was Prime Minister of the United Kingdom; Hirohito was Emperor of Japan; Louis XVI was King of France). Royal styles take capitals (Her Majesty; His Highness); exceptions may apply for particular offices.

Religions, deities, philosophies, doctrines

 * Religions, sects, and churches and their followers (in noun or adjective form) start with a capital letter. Generally, "the" is not capitalized before such names (the Unitarians, not The Unitarians).
 * Religious texts are capitalized, but often not italicized (the Bhagavad Gita, the Quran, the Talmud, the Granth Sahib, the Bible). Do not capitalize "the" when using it in this way. Some derived adjectives are capitalized by convention, and some are not (biblical, but Quranic); if unsure, check a dictionary.
 * Honorifics for deities, including proper names and titles, start with a capital letter (God, Allah, the Lord, the Supreme Being, the Great Spirit, the Horned One, Bhagavan). Do not capitalize "the" in such cases or when referring to major religious figures or characters from mythology (the Prophet, the Messiah, the Virgin). Common nouns for deities and religious figures are not capitalized (many gods; the god Woden; saints and prophets).
 * Pronouns for figures of veneration or worship are not capitalized, even if capitalized in a religion's scriptures (God and his will).
 * Broad categories of mythical or legendary beings start with lower-case letters (elf, fairy, nymph, unicorn, angel), although in works of fantasy, such as the novels of J. R. R. Tolkien and some video games, initial capitals are sometimes used to indicate that the beings form a culture or race in a fictional universe. Capitalize the names or titles of individual creatures (the Minotaur, Pegasus) and of groups whose name and membership are fixed (the Magi, or the Three Wise Men, the Furies). Generalized references are not capitalized (these priests; several wise men; cherub-like).
 * Spiritual or religious events are capitalized only when referring to specific incidents or periods (the Great Flood and the Exodus; but annual flooding and an exodus of refugees).
 * Philosophies, theories, movements, and doctrines use lower case unless the name derives from a proper name (capitalism versus Marxism) or has become a proper name (republican, a system of political thought; Republican, a political party). Use lower case for doctrinal topics or canonical religious ideas (as opposed to specific events), even if they are capitalized by some religious adherents (virgin birth, original sin, transubstantiation).
 * Platonic or transcendent ideals are capitalized in the context of philosophical doctrine (Truth, the Good); used more broadly, they are in lower case (Superman represents American ideals of truth and justice). Use capitals for personifications represented in art (the guidebook mentioned statues of Justice and Liberty).
 * Eponyms are capitalized (Edwardian, De Morgan's laws, Alice in Wonderland syndrome, plaster of Paris, Platonic idealism, Draconian constitution of Athens), except in idiomatic uses disconnected from the original context and usually lower-cased in sources (a platonic relationship; complained of draconian workplace policies). An entire phrase in which an eponym is an adjective is not capitalized except when the phrase is itself a proper name (e.g., the title of a published work: The China Syndrome).

Calendar items

 * Months, days of the week, and holidays start with a capital letter (June, Monday; the Fourth of July refers only to the US Independence Day – otherwise July 4 or 4 July).
 * Seasons are in lower case (her last summer; the winter solstice; spring fever), except in personifications or in proper names for periods or events (Old Man Winter; competed on the Spring Circuit).

Animals, plants, and other organisms
When using taxonomic ("scientific") names, capitalize and italicize the genus: Berberis, Erithacus. (Supergenus and subgenus, when applicable, are treated the same way.) Italicize but do not capitalize taxonomic ranks at the level of species and below: Berberis darwinii, Erithacus rubecula superbus, Acacia coriacea subsp. sericophylla; no exception is made for proper names forming part of scientific names. Higher taxa (order, family, etc.) are capitalized in Latin (Carnivora, Felidae) but not in their English equivalents (carnivorans, felids); they are not italicized in either form, except for viruses, where all names accepted by the ICTV are italicized (Retroviridae).

Cultivar and cultivar group names of plants are not italicized, and are capitalized (including the word Group in the name); cultivar names appear within single quotes (Malus domestica 'Red Delicious'), while cultivar groups do not (Cynara cardunculus Scolymus Group).

English vernacular ("common") names are given in lower case in article prose (plains zebra, mountain maple, and southwestern red-tailed hawk) and in sentence case at the start of sentences and in other places where the first letter of the first word is capitalized. They are additionally capitalized where they contain proper names: Przewalski's horse, California condor, and fair-maid-of-France. This applies to species and subspecies, as in the previous examples, as well as to general names for groups or types of organism: bird of prey, oak, great apes, Bryde's whales, livestock guardian dog, poodle, Van cat, wolfdog. When the common name coincides with a scientific taxon, do not capitalize or italicize, except where addressing the organism taxonomically: A lynx is any of the four medium-sized wild cat species within the genus Lynx. Non-English vernacular names, when relevant to include, are handled like any other foreign-language terms: italicized as such, and capitalized only if the rules of the native language require it. Non-English names that have become English-assimilated are treated as English (ayahuasca, okapi).

Standardized breeds should generally retain the capitalization used in the breed standards. Examples: German Shepherd, Russian White goat, Berlin Short-faced Tumbler. As with plant cultivars, this applies whether or not the included noun is a proper name, in contrast to how vernacular names of species are written. However, unlike cultivars, breeds are never put in single quotation marks, and their names are never part of a scientific name. A species term appended at the end for disambiguation ("cat", "hound", "horse", "swine", etc.) should not be capitalized, unless it is a part of the breed name itself and is consistently presented that way in the breed standards (rare cases include Norwegian Forest Cat and American Quarter Horse).

Create redirects from alternative capitalization and spelling forms of article titles, and from alternative names, e.g., Adélie Penguin, Adelie penguin, Adelie Penguin and Pygoscelis adeliae should all redirect to Adélie penguin.

Celestial bodies
The words sun, earth, moon and solar system do not take capitals in general use (The sun was over the mountain top; The tribal people thought of the whole earth as their home). They are capitalized when the entity is personified (Sol Invictus ('Unconquered Sun') was the Roman sun god) or when used as the name of a specific body in a scientific or astronomical context (The Moon orbits the Earth; but Io is a moon of Jupiter).

Names of planets, moons, asteroids, comets, stars, constellations, and galaxies are proper names, and therefore capitalized (The planet Mars is in the constellation Gemini, near the star Pollux). The first letter of every word in such a name is capitalized (Alpha Centauri and not Alpha centauri; Milky Way, not Milky way). Words such as comet and galaxy should be capitalized when they form part of a proper name, but not when they are used as a generic term (Halley's Comet is the most famous of the comets; The Andromeda Galaxy is a spiral galaxy).

Compass points
Do not capitalize directions such as north, or their related forms (We took the northern road), except where they are parts of proper names (Great North Road, Great Western Drive, South Pole).

Capitalize names of regions if they have attained proper-name status, including informal conventional names (Southern California; the Western Desert), and derived terms for people (e.g., a Southerner as someone from the Southern United States). Do not capitalize descriptive names for regions that have not attained the status of proper names, such as southern Poland.

Composite directions may or may not be hyphenated, depending on the variety of English adopted in the article. Southeast Asia and northwest are more common in American English; but South-East Asia and north-west in British English. In cases such as north–south dialogue and east–west orientation, use an en dash; see.

Proper names versus generic terms
Capitalize names of particular institutions (the founding of the University of Delhi; the history of Stanford University) but not generic words for institutions (the high school is near the university). Do not capitalize the at the start of an institution's name, regardless of the institution's preferred style. There are rare exceptions, when a leading The is represented by a T in the organization's acronym: The International Cat Association (TICA).

Treat political or geographic units similarly: The city has a population of 55,000; The two towns merged to become the City of Smithville. Do not mimic the style of local newspapers which refer to their municipality as the City or The City; an exception is the City of London, referred to as the City in a context that already makes the subject clear, as distinct from London and Greater London. When in doubt, use the full name for accessibility reasons; users of text-to-speech systems usually cannot hear a difference between city and City.

Ligatures
Ligatures should be used in languages in which they are standard (hence Moreau's last words were clin d'œil is preferable to Moreau's last words were clin d'oeil) but not in English (encyclopedia or encyclopaedia, not encyclopædia), except in proper names (Æthelstan, not Aethelstan).

Abbreviations
Abbreviations are shortened forms of words or phrases. In strict analysis, they are distinct from contractions, which use an apostrophe (e.g., won't, see ), and initialisms. An initialism is formed from some or all of the initial letters of words in a phrase. Below, references to abbreviations should be taken to include acronyms, and the term acronym to apply also to initialisms.

Write first occurrences in full
When an abbreviation will be used in an article, first introduce it using the full expression:

Do not use capitals in the full version merely because capitals are used in the abbreviation: an early Local Area Network (LAN).

Except in special circumstances, common abbreviations (such as PhD, DNA, USSR) need not be expanded even on first use.

Plural forms
Pluralize acronyms by adding -s or -es: Three CD-ROMs and two BIOSes were released. Do not use apostrophes to form plurals: Three CD-ROM's and two BIOS's were released.

Punctuation and spacing
An abbreviation may or may not be terminated with a full point (also called a period or full stop). A consistent style should be maintained within an article. North American usage is typically to end all abbreviations with a period/point (Dr. Smith of 42 Drummond St.) but in common British and Australian usage, no period/point is used if the abbreviation (contraction) ends in the last letter of the unabbreviated form (Dr Smith of 42 Drummond St) unless confusion could result. This is also common practice in scientific writing. Regardless of punctuation, words that are abbreviated to more than one letter are spaced (op. cit. not op.cit. or opcit). There are some exceptions: PhD for "Philosophiae Doctor"; BVetMed for "Bachelor of Veterinary Medicine". In most situations, Wikipedia uses no such punctuation inside acronyms and initialisms: GDP, not G.D.P.

US and U.S.
US is a commonly used abbreviation for United States, although U.S. – with periods and without a space – remains common in North American publications, including in news journalism. Multiple American style guides, including The Chicago Manual of Style (since 2010), now deprecate "U.S." and recommend "US".

For commonality reasons, use US by default when abbreviating, but retain U.S. in American or Canadian English articles in which it is already established, unless there is a good reason to change it. Because use of periods for abbreviations and acronyms should be consistent within any given article, use US in an article with other country abbreviations, and especially avoid constructions like the U.S. and the UK. In longer abbreviations that incorporate the country's initials (USN, USAF), never use periods. When the United States is mentioned with one or more other countries in the same sentence, US (or U.S.) may be too informal, especially at the first mention or as a noun instead of an adjective (France and the United States, not France and the US). Do not use the spaced U. S. or the archaic U.S. of A., except when quoting. Do not use U.S.A. or USA except in a quotation, as part of a proper name (Team USA), or in certain technical and formal uses (e.g., the ISO 3166-1 alpha-3, FIFA, and IOC country codes).

Circa
To indicate approximately, the use of, showing as c. , is preferred over circa, c., ca., or approx.

Avoid unwarranted use
Avoid abbreviations when they might confuse the reader, interrupt the flow, or appear informal. For example:
 * Do not use approx. for approximate(ly) except in an infobox or table (in which case use at first occurrence: approx.).
 * Do not use the legalism Smith J for Justice Smith.

Do not invent
Avoid devising new abbreviations, especially acronyms. For example, World Union of Billiards is good as a of Union Mondiale de Billard, but neither it nor the reduction WUB is used by the organization or by independent sources; use the original name and its official abbreviation, UMB.

If it is necessary to abbreviate in a tight space, such as a column header in a table, use widely recognized abbreviations. For example, for New Zealand gross national product, use NZ and GNP, with a link if the term has not already been written out in the article: NZ GNP. Do not make up initialisms such as NZGNP.

HTML tags and templates
Either or  can be used for abbreviations and acronyms: WHO or  will generate WHO; hovering over the rendered text causes a tooltip of the long form to pop up.

Ampersand
In normal text and headings, use and instead of the ampersand (&): January 1 and 2, not January 1 & 2. But retain an ampersand when it is a legitimate part of the style of a proper noun, the title of a work, or a trademark, such as in Up &amp; Down or AT&T. Elsewhere, ampersands may be used with consistency and discretion where space is extremely limited (e.g., tables and infoboxes). Quotations may be cautiously modified, especially for consistency where different editions are quoted, as modern editions of old texts routinely replace ampersands with and (just as they replace other disused glyphs, ligatures, and abbreviations). Another frequent permissible but not required use is in short bibliographic references to works by multiple authors, e.g.:.

Emphasis
Italics are used for emphasis, rather than boldface or capitals. But overuse diminishes its effect; consider rewriting instead.

Use  or for emphasis. This allows user style sheets to handle emphasis in a customized way, and helps reusers and translators.
 * Correct:
 * Correct:

Titles
Use italics for the titles of works (such as books, films, television series, named exhibitions, computer games, music albums, and artworks). The titles of articles, chapters, songs, episodes, storylines, research papers and other short works instead take double quotation marks.

Italics are not used for major religious works (the Bible, the Quran, the Talmud). Many of these titles should also be in title case.

Words as words
Use italics when a word or character  or a string of words up to one sentence (the term panning is derived from panorama; the most common letter in English is e). When a whole sentence is mentioned, double quotation marks may be used instead, with consistency (The preposition in She sat on the chair is on; or The preposition in "She sat on the chair" is "on"). Quotation marks may also be used for shorter material to avoid confusion, such as when italics are already heavily used in the page for another purpose (e.g., for many non-English words and phrases). (to discuss grammar, wording, punctuation, etc.) is different from (in which something is usually expressed on behalf of a quoted source). Quotation is done with quotation marks, never italics, nor both at once

A closely related use of italics is when introducing or distinguishing terms: The natural numbers are the integers greater than 0.

Foreign words
Italics is indicated for phrases in other languages and for isolated foreign words that are not common in everyday English. However, proper names (such as place names) in other languages are not usually italicized, nor are terms in non-Latin scripts. The template and its variants support all ISO 639 language codes, correctly identifying the language and automatically italicizing for you. Please use these templates rather than just manually italicizing non-English material.

Scientific names
Use italics for the scientific names of plants, animals, and all other organisms except viruses at the genus level and below (italicize Panthera leo and Retroviridae, but not Felidae). The hybrid sign is not italicized (Rosa × damascena), nor is the "connecting term" required in three-part botanical names (Rosa gallica subsp. officinalis).

Quotations in italics
Do not use italics for quotations. Instead, use quotation marks for short quotations and block quoting for long ones.

Italics within quotations
Use italics within quotations to reproduce emphasis that exists in the source material. If it is not clear that the source already included italics (or some other styling) for emphasis, add the editorial note [emphasis in original] after the quotation.

If adding emphasis that was not in the original, add the editorial note [emphasis added] after the quotation.
 * "Now cracks a noble heart. Good night sweet prince: And sing thee to thy rest." [emphasis added]

Effect on nearby punctuation
Italicize only the elements of the sentence affected by the emphasis. Do not italicize surrounding punctuation.
 * What are we to make of (The question mark applies to the whole sentence, not just to the emphasized that, so it should not be italicized.)
 * What are we to make of ?
 * Four of Patrick White's most famous novels are A Fringe of Leaves, The Aunt's Story, Voss, and The Tree of Man. (The commas, the period, and the word and are not italicized.)

Quotations
Brief quotations of copyrighted text may be used to illustrate a point, establish context, or attribute a point of view or idea. While quotations are an indispensable part of Wikipedia, try not to overuse them. Using too many quotes is incompatible with an encyclopedic writing style and may be copyright infringement, and so most of the content should be in the editor's own words. Consider paraphrasing quotations into plain and concise text when appropriate (while being aware that close paraphrasing can still violate copyright). It is incorrect to put quotations in italics unless the material would be italicized for some other reason.

Original wording
Quotations must be verifiably attributed, and the wording of the quoted text must be faithfully reproduced. This is referred to as the. Where there is good reason to change the wording, bracket the changed text; for example, "Ocyrhoe told him his fate" might be quoted as "Ocyrhoe told [her father] his fate". If there is a significant error in the original, follow it with (producing [sic]) to show that the error was not made by Wikipedia. When applied to a title parameter within a tag set or similar text creating links, the syntax of the template may be adjusted to (producing [sic] in the resulting linked text). However, insignificant spelling and typographic errors should simply be silently corrected (for example, correct basicly to basically).

Use ellipses to indicate omissions from quoted text. Legitimate omissions include extraneous, irrelevant, or parenthetical words, and unintelligible speech (umm and hmm), but do not omit text where doing so would remove important context or alter the meaning of the text. Vulgarities and obscenities should be shown exactly as they appear in the quoted source; Wikipedians should never bowdlerize words (G-d d--m it!), but if the text being quoted itself does so, copy the text verbatim and use to indicate that the text is quoted as shown in the source.

In direct quotations, retain dialectal and archaic spellings, including capitalization (but not archaic glyphs and ligatures, as detailed below in ).

Point of view
Quotation should be used, with attribution, to present emotive opinions that cannot be expressed in Wikipedia's own voice, but never to present cultural norms as simply opinional:


 * Acceptable: Siskel and Ebert called the film "unforgettable".
 * Unacceptable: The site is considered "sacred" by the religion's scriptures.

Concise opinions that are not overly emotive can often be reported with attribution instead of direct quotation. Use of quotation marks around simple descriptive terms can imply something doubtful regarding the material being quoted; sarcasm or weasel words such as supposedly or so-called, might be inferred.


 * Permissible: Siskel and Ebert called the film interesting.
 * Unnecessary and may imply doubt: Siskel and Ebert called the film "interesting".
 * Should be quoted: Siskel and Ebert called the film "interesting but heart-wrenching".

Typographic conformity
A quotation is not a facsimile and, in most cases, it is not a requirement that the original formatting be preserved. Formatting and other purely typographical elements of quoted text should be adapted to English Wikipedia's conventions without comment, provided that doing so will not change or obscure meaning or intent of the text. These are alterations which make no difference when the text is read aloud, for example:


 * Normalize dashes and hyphens: see . Use the style chosen for the article: unspaced em dash or spaced en dash.
 * Convert apostrophes and quotation marks to Wikipedia's style:
 * These should be straight, not curly or slanted. See.
 * When quoting a quotation that itself contains a quotation, alternate between using double and single quotes for each quotation. See for details.
 * When quoting text from non-English languages, the outer punctuation should follow the Manual of Style for English quote marks. If there are nested quotations, follow the rules for correct punctuation in that language. If there are multiple styles for a language, the one used by the Wikipedia for that language is preferred unless the punctuation itself is under discussion.
 * The cynical response "L'auteur aurait dû demander : « à quoi sert-il d'écrire ceci ? » mais ne l'a pas fait" was all he wrote.
 * Remove spaces before punctuation such as periods and colons.
 * Generally preserve bold and italics, but most other styling should be altered. Underlining, spac ing within words, co lor s, ALL CAPS, , etc. should generally be normalized to plain text. If it indicates emphasis, use italic   or, in an already-italic passage, boldface (with ). For titles of books, articles, poems, and so forth, use italics or quotation marks following the guidance for titles. Italics can also be added to mark up non-English terms (with the  template), for an organism's scientific name, and to indicate a words-as-words usage.
 * Expand an abbreviation (not already used in the content before the quotation) as a square-bracketed change, or explain it using.
 * Normalize archaic glyphs and ligatures in English that are unnecessary to the meaning. Examples include æ→ae, œ→oe, ſ→s, and þe→the.

However, national varieties should not be changed, as these may involve changes in vocabulary. For example, a quotation from a British source should retain British spelling, even in an article that otherwise uses American spelling. Numbers also usually should not be reformatted.

Direct quotation should not be used to preserve the formatting preferred by an external publisher (especially when the material would otherwise be unchanged), as this tends to have the effect of scare-quoting:
 * The animal is listed as endangered on the IUCN Red List of Threatened Species.
 * The animal is listed as "Endangered" on the IUCN Red List of Threatened Species.

Italics can be used to mark a particular usage as a term of art (a case of "words as words"), especially when it is unfamiliar or should not be reworded by a non-expert:
 * The animal is listed as critically endangered on the IUCN Red List of Threatened Species.

When quoting a complete sentence, it is usually recommended to keep the first word capitalized. However, if the quoted passage has been integrated into the surrounding sentence (for example, with an introduction such as "X said that"), the original capital letter may be lower-cased.
 * LaVesque's report stated: "The equipment was selected for its low price. This is the primary reason for criticism of the program."
 * LaVesque's report said that "the equipment was selected for its low price".
 * The program was criticized primarily because "the equipment was selected for its low price", according to LaVesque.

It is normally unnecessary to explicitly note changes in capitalization. However, for more precision, the altered letter may be put inside square brackets: "The" → "[t]he".
 * The program was criticized primarily because "[t]he equipment was selected for its low price", according to LaVesque.

Attribution
The reader must be able to determine the source of any quotation, at the very least via a footnote. The source must be named if the quotation is an opinion. When attributing a quotation, avoid characterizing it in a biased manner.

Quotations within quotations
See.

Linking
Be conservative when linking within quotations; link only to targets that correspond to the meaning clearly intended by the quote's author. Where possible, link from text outside of the quotation instead – either before it or soon after. (If quoting hypertext, add an editorial note, [link in original] or [link added], as appropriate, to avoid ambiguity as to whether the link was made by the original author.)

Block quotations
Format a long quote (more than about forty words or a few hundred characters, or consisting of more than one paragraph, regardless of length) as a block quotation, indented on both sides. Block quotations should be enclosed in.

Do not enclose block quotations in quotation marks (and especially avoid large, decorative quotation marks; those provided by the template have been disabled in mainspace). Block quotations using a colored background are also discouraged.

Use and so on only for actual quotations; indentation for other purposes is done differently.

It is conventional to precede a block quotation with an introductory sentence (or sentence fragment) and append the source citation to that line. Alternatively, the template provides parameters for attribution and citation which will appear below the quotation. This below-quotation attribution style is intended for famous quotations and is unusual in articles because it may strike an inappropriate tone. A quotation with no cited source should be flagged with, or deleted.

Line breaks and indentation inside a or  are generally ignored; use poem or  for poetry, lyrics, and similar material:

This gives: "What this grim, ungainly, ghastly, gaunt, and ominous bird of yore         Meant in croaking 'Nevermore.'"

Or quote such material inline, with line breaks indicated by, and paragraph or stanza breaks by.

Pull quotes do not belong in Wikipedia articles. These are the news and magazine style of "pulling" material already in the article to reuse it in attention-grabbing decorative quotations. This unencyclopedic approach is a form of editorializing, produces out-of-context and undue emphasis, and may lead the reader to conclusions not supported in the material.

Foreign-language quotations
Quotations from foreign-language sources should appear with a translation into English, preferably a modern one. Quotations that are translations should be explicitly distinguished from those that are not. Indicate the original source of a translation (if it is available, and not first published within Wikipedia), and the original language (if that is not clear from the context).

If the original, untranslated text is available, provide a reference for it or include it, as appropriate.

When editors themselves translate foreign text into English, care must always be taken to include the original text, (except for non-Latin-based writing systems, and best done with the  template which both italicizes as appropriate and provides language metadata); and to use actual and (if at all possible) common English words in the translation. Unless you are certain of your competency to translate something, see Translation for assistance.

Apostrophes

 * Use straight apostrophes ('), not curly apostrophes (’). Do not use accent marks or backticks (`) as apostrophes.
 * Templates such as and  are helpful when an apostrophe (or single quote) appears at the beginning or end of text in italics or bold, because italics and bold are themselves indicated by sequences of single quotes. Example: Dynasty first season (markup: ).
 * Letters resembling apostrophes, such as the okina ( – markup: ), saltillo ( – markup: ), Hebrew ayin or Arabic ʿayn ( – markup: ) and Arabic hamza ( – markup:), should be represented by those templates or by their Unicode values.
 * Templates cannot be used in article titles; if necessary, use the corresponding Unicode character directly. Per WP:TITLESPECIALCHARACTERS, also make a redirect from the ASCII form to aid searches. Forms without apostrophe-like characters are sometimes preferred by WP:COMMONNAME (e.g. Hawaii but not Kealii Reichel).
 * For Wade–Giles romanizations of Mandarin Chinese, use.
 * For languages with ejective consonants and the like, use.
 * For the Cyrillic soft sign, when indicated at all, use or.
 * For usage of the possessive apostrophe, see.
 * For further treatment of apostrophe usage (possessive, elision, formation of certain plurals, foreign-language issues) see the article Apostrophe.
 * For further treatment of apostrophe usage (possessive, elision, formation of certain plurals, foreign-language issues) see the article Apostrophe.

Quotation marks
In the material below, the term quotation includes conventional uses of quotation marks such as for titles of songs, chapters, episodes, and so on. Quotation marks are also used in other contexts, such as in cultivar names.

Quotation characters

 * Use "straight" quotation marks, not “curly” ones. (For single-apostrophe quotes: 'straight', not ‘curly’.)
 * Do not use accent marks, backticks (`text´), low-high („ “) or guillemet (« ») marks as quotation marks (except when such marks are to quoted non-English text – see MOS:CONFORM). The symbols ′ and ″ seen in edit window dropdowns are prime and double prime: these are used to designate units of angular measurement, and not as apostrophes or quote marks.
 * Quotation marks and apostrophes in imported material should be changed if necessary to comply with the above.

Double or single
Most quotations take double quotation marks (Bob said: "Jim ate the apple."). Exceptions:
 * Plant cultivars take single quotation marks (Malus domestica 'Golden Delicious'; see Naming conventions (flora)).
 * Glosses that translate or define unfamiliar terms take single quotes; simple glosses require no comma before the definition (Turkic qazaq 'freebooter' is the root of Cossack; republic comes from Latin res publica, loosely meaning 'public affair'.). The Gloss template can be used for this; e.g.  yields: casa house.

For a quotation within a quotation
Use single quotes: For deeper nesting, alternate between single and double quotes:
 * Darwin wrote in his introduction that "the maxim 'de minimis lex non curat' does not apply to science".
 * He said, "That book asserts, 'Confucius said "Everything has beauty, but not everyone sees it.

For quote marks in immediate succession, add a sliver of space by using " ', ' ", or (as in the example just given) " ' ":
 * He announced, "The answer was 'Yes! Markup:
 * He announced, "The answer was 'Yes!'" (simply jamming things together looks awful in most fonts)
 * He announced, "The answer was 'Yes!'" (a regular space is too much)

Article openings
In the bolded text typically appearing at the opening of an article:
 * Any quotation marks that are part of the title should be in bold just like the rest of the title.
 * From "A" Is for Alibi: "A" Is for Alibi is a mystery novel ...
 * Quotation marks not part of the article title should not be bolded.
 * From Jabberwocky: "Jabberwocky" is a nonsense poem ...
 * From Babe Ruth: George Herman "Babe" Ruth was an American baseball player ...

Punctuation before quotations
If a non-quoted but otherwise identical construction would work grammatically without a comma, using a comma before a quotation embedded within a sentence is optional: The comma-free approach is often used with partial quotations: A comma is required when it would be present in the same construction if none of the material were a quotation: Do not insert a comma if it would confuse or alter the meaning: It is clearer to use a colon to introduce a quotation if it forms a complete sentence, and this should always be done for multi-sentence quotations: No additional punctuation is necessary for an explicit words-as-words scenario:
 * The report stated "There was a 45% reduction in transmission rate." (Cf. the non-quotation The report stated there was a 45% reduction in transmission rate.)
 * The report stated, "There was a 45% reduction in transmission rate."
 * The report observed "a 45% reduction in transmission rate".
 * In Margaret Mead's view, "we must recognize the whole gamut of human potentialities" to enrich our culture.
 * Caitlyn Jenner expressed concerns about children "who are coming to terms with being true to who they are". (Accurate quote of a statement about children – specifically those children "who are coming to terms...")
 * Caitlyn Jenner expressed concerns about children, "who are coming to terms with being true to who they are". (Changes the meaning to imply Jenner was expressing concern about children, while separately observing that children, in general, "are coming to terms...")
 * The report stated: "There was a 45% reduction in transmission rate."
 * In a letter to his son, Albert Einstein wrote: "Life is like riding a bicycle. To keep your balance you must keep moving."
 * The message was unintelligible except for the fragments "help soon" and "how much longer before".

Names and titles
Quotation marks should be used for the following names and titles: • Articles and chapters (books and periodicals italicized)

• Short stories (books and periodicals italicized)

• Sections of musical pieces (pieces italicized)

• Individual strips from comics and webcomics (comics italicized)

• Poems (long or epic poems italicized)

• Songs (albums, song cycles, operas, operettas, and oratorios italicized)

• Individual episodes of television and radio series and serials (series title italicized)

The Beatles wrote "Lucy in the Sky with Diamonds" for their album Sgt. Pepper's Lonely Hearts Club Band.

Do not use quotation marks or italics for: • Ancient writings

• Concert tours

• Locations

• Myths and epics

• Prayers

Many, but not all, of the above items should also be in title case.

Punctuation inside or outside
Use the "logical quotation" style in all articles, regardless of the variety of English in which they are written. Include terminal punctuation within the quotation marks only if it was present in the original material, and otherwise place it after the closing quotation mark. For the most part, this means treating periods and commas in the same way as question marks: keep them inside the quotation marks if they apply only to the quoted material and outside if they apply to the whole sentence. Examples are given below.
 * Did Darla say, "Here I am"? (question mark applies to whole sentence)
 * Did Darla say, "Here I am?" (incorrect to apply the question mark to the quotation)
 * Darla said, "Where am I?" (question mark applies to quoted material only)

If the quotation is a single word or a sentence fragment, place the terminal punctuation outside the closing quotation mark. When quoting a full sentence, the end of which coincides with the end of the sentence containing it, place terminal punctuation inside the closing quotation mark.
 * Miller wanted, he said, "to create something timeless".
 * Miller said: "I wanted to create something timeless."

If the quoted sentence is followed by a clause that should be preceded by a comma, omit the full stop (period), and do not replace it with a comma the quotation. Other terminal punctuation, such as a question mark or exclamation mark, may be retained.
 * Livingston then said, "It is done", and turned to the people.
 * Livingston then exclaimed, "It is done!", and turned to the people.

If the quoted sentence is followed by a clause identifying the speaker, use a comma outside the quotation mark instead of a full stop inside it, but retain any other terminal punctuation, such as a question mark.
 * "There is no strife, no prejudice, no national conflict in outer space as yet", said Kennedy.
 * By asking "Who are you?", da Gama prompts Adamastor to tell his story.

Do not follow quoted words or fragments with commas inside the quotation marks, except where a longer quotation has been broken up and the comma is part of the full quotation.
 * "I began to change, opening the way to confidence and courage", said Turner.
 * "I began to change," said Turner, "opening the way to confidence and courage."
 * "I began to change, opening the way", said Turner, "to confidence and courage."
 * "I began to change, opening the way," said Turner, "to confidence and courage."

Quotation marks and external links
External links to article titles should have the title in quotes inside the link. The CS1 and CS2 citation templates do this automatically, and untemplated references should do the same.


 * (Using cite news)
 * Kiefer, Francine (May 29, 1998). "Clinton: The Early Years". The Christian Science Monitor. (Untemplated)
 * Kiefer, Francine (May 29, 1998). "Clinton: The Early Years". The Christian Science Monitor. (Untemplated)

Quotation marks and internal links
Internal links (wikilinks) accompanied by quotation marks should usually have the quotes outside the link. This applies to titles of works in quotation marks (songs, episodes, etc.) However, quotation marks are needed inside wikilinks when the quotation mark is part of the link, or where the linked display text includes quotation marks indicating slang, nicknames, common names, or similar usage.
 * Play it, Sam. Play "As Time Goes By". (Using  .)
 * Play it, Sam. Play "As Time Goes By". (Using .)
 * The term soccer comes from Oxford "-er" slang, which was prevalent at the University of Oxford in England from about 1875....
 * A Cockney accent drops the "r" after a vowel.
 * The Proletarian Sports Society "Dynamo" was established in Moscow in 1923.
 * President Suharto's "New Order" administration received U.S. support for its economic policies.
 * Japan's "Lost Decades" began in 1991.

Brackets and parentheses
This section applies to both round brackets, often called parentheses, and square brackets [ ].

If a sentence contains a bracketed phrase, place the sentence punctuation outside the brackets (as shown here). However, where one or more sentences are wholly inside brackets, place their punctuation inside the brackets. There should be no space next to the inner side of a bracket. An opening bracket should usually be preceded by a space. This may not be the case if it is preceded by an opening quotation mark, another opening bracket, or a portion of a word:
 * He rose to address the meeting: "(Ahem) ... Ladies and gentlemen, welcome!"
 * Only the royal characters in the play ([Prince] Hamlet and his family) habitually speak in blank verse.
 * We journeyed on the Inter[continental].
 * Most people are right-handed. (Some people are left-handed, but that does not make right-handed people "better" than left-handed people.)

There should be a space after a closing bracket, except where a punctuation mark follows (though a spaced dash would still be spaced after a closing bracket) and in unusual cases similar to those listed for opening brackets.

Avoid adjacent sets of brackets. Either put the parenthetical phrases in one set separated by semicolons, or rewrite:
 * Nikifor Grigoriev (c. 1885 – 1919) (also known as Matvii Hryhoriiv) was a Ukrainian insurgent leader.
 * Nikifor Grigoriev (c. 1885 – 1919; also known as Matvii Hryhoriiv) was a Ukrainian insurgent leader.
 * Nikifor Grigoriev (c. 1885 – 1919) was a Ukrainian insurgent leader. He was also known as Matvii Hryhoriiv.

Square brackets are used to indicate editorial replacements and insertions within quotations, though this should never alter the intended meaning. They serve three main purposes:
 * To clarify: She attended [secondary] school, where this was the intended meaning, but the type of school was unstated in the original sentence.
 * To reduce the size of a quotation: X contains Y, and under certain circumstances, X may contain Z as well may be reduced to X contains Y [and sometimes Z]. When an ellipsis (...) is used to indicate that material is removed from a direct quotation, it should not normally be bracketed.
 * To make the grammar work: Referring to someone's statement "I hate to do laundry", one could properly write She "hate[s] to do laundry".

If a sentence includes subsidiary material enclosed in square or round brackets, it must still carry terminal punctuation those brackets, regardless of any punctuation within the brackets. However, if the entire sentence is within brackets, the closing punctuation falls within the brackets. (This sentence is an example.)

Brackets and linking
Square brackets inside of links must be escaped:

The nowiki markup can also be used: [Doe] or [etc.].

If a URL itself contains square brackets, the wiki-text should use the URL-encoded form, rather than ... . This will avoid truncation of the link after.

Ellipses
Use an ellipsis (plural ellipses) if material is omitted in the course of a quotation, unless square brackets are used to gloss the quotation.


 * Wikipedia's style for an ellipsis is three unspaced dots ; do not use the precomposed ellipsis character or three dots separated by spaces
 * Generally, use a non-breaking space before an ellipsis, and a regular space after it:
 * But where an ellipsis is immediately followed by any of  or by a closing quotation mark (single or double), use a non-breaking space before the ellipsis, and no space after it:
 * (Place terminal punctuation after an ellipsis only if it is textually important, as is often the case with exclamation marks and question marks but rarely with periods.)
 * Or, if the ellipsis immediately follows a quotation mark, use no space before the ellipsis, and a non-breaking space after it:
 * Or, if the ellipsis immediately follows a quotation mark, use no space before the ellipsis, and a non-breaking space after it:


 * Three dots are occasionally used to represent a pause in or suspense of speech, in which case the punctuation is retained in its original form: Virginia's startled reply was "Could he ...? No, I can't believe it!". When it indicates an incomplete word, no space is used between the word fragment(s) and the ellipsis: The garbled transmission ended with "We are stranded near San L...o", interpreted as a reference to either San Leandro or San Lorenzo.
 * Three dots are occasionally used to represent a pause in or suspense of speech, in which case the punctuation is retained in its original form: Virginia's startled reply was "Could he ...? No, I can't believe it!". When it indicates an incomplete word, no space is used between the word fragment(s) and the ellipsis: The garbled transmission ended with "We are stranded near San L...o", interpreted as a reference to either San Leandro or San Lorenzo.


 * With square brackets
 * Square brackets may be placed around an ellipsis that indicates omitted text to distinguish it from an ellipsis that is part of the quoted text: She retorted: "How do I feel? How do you I ... This is too much! [...] Take me home!". In this example, the first ellipsis is part of the quoted text and the second ellipsis (in square brackets) indicates omitted text.

Commas
  A pair of commas can bracket an appositive, relative clause, or parenthetical phrase (as can brackets or dashes, though with greater interruption of the sentence). For example:

Always use a pair of commas for this, unless another punctuation mark takes the place of the second comma: 

 Don't let other punctuation distract you from the need for a comma, especially when the comma collides with a bracket or parenthesis:

</li>

<li> Modern writing uses fewer commas; there are usually ways to simplify a sentence so that fewer are needed.

</li>

<li> In geographical references that include multiple levels of subordinate divisions (e.g., city, state/province, country), a comma separates each element and follows the last element unless followed by terminal punctuation or a closing parenthesis. The last element is treated as parenthetical.

Also include commas when the geographical element is used as a disambiguator:

</li>

<li> Dates in month–day–year format require a comma after the day, as well as after the year, unless followed by other punctuation. The last element is treated as parenthetical.

</li>

<li> Place quotation marks by following. This is known as "logical quotation".

</li>

<li> A comma may be included before a quotation embedded within a sentence. </li>

</ul>

Serial commas
A serial comma (sometimes also known as an Oxford comma or Harvard comma) is a comma used immediately before a conjunction (and, or, nor) in a list of three or more items.

Editors may use either convention so long as each article is internally consistent. Serial commas are more helpful when article text is complex, such as a list with multi-word items (especially if one contains its own "and" or a series of probably unfamiliar terms.

However, there are cases in which either omitting or including the serial comma results in ambiguity:

In such cases of ambiguity, clarify one of four ways:
 * Add or remove the serial comma.
 * Use separate sentences, bullet lists, or some other structural change to clarify.
 * Recast the sentence ("friends" case):
 * To list two people: The author thanked her friends Sinéad O'Connor and Bob Marley.
 * Clearer: The author thanked two friends – Sinéad O'Connor and Bob Marley.
 * To list several people:
 * The author thanked Sinéad O'Connor, Bob Marley and her friends or
 * The author thanked Sinéad O'Connor, Bob Marley, and her friends.
 * But not: The author thanked Bob Marley, Sinéad O'Connor[,] and her friends –introduces ambiguity about her.
 * Recast the sentence ("friend" case):
 * To list two people: The author thanked Bob Marley and her friend, Sinéad O'Connor.
 * Or be more specific when possible (the commas here set off non-restrictive appositives): The author thanked her childhood friend, Sinéad O'Connor, and her mentor, Bob Marley.
 * To list three people: The author thanked Bob Marley, Sinéad O'Connor, and a friend.
 * Clarity with gender-specific terms such as mother can be tricky; The author thanked her mother, Kim Thayil, and Sinéad O'Connor is unclear because readers may not know Kim Thayil is male and wouldn't be the same person as the mother.
 * Clearer: The author thanked Kim Thayil, Sinéad O'Connor, and her own mother or The author thanked her mother and musicians Kim Thayil and Sinéad O'Connor.

Colons
A colon introduces something that demonstrates, explains, or modifies what has come before, or is a list of items that has just been introduced. The items in such a list may be separated by commas, or if they are more complex and perhaps themselves contain commas, the items should be separated by semicolons or arranged in a bulleted list.

A colon may also be used to introduce direct speech enclosed within quotation marks.

In most cases, a colon works best with a complete grammatical sentence before it. When what follows the colon is also a complete sentence, start it with a capital letter, but otherwise do not capitalize after a colon except where doing so is needed for another reason, such as for a proper name. When a colon is being used as a separator in an article title, section heading, or list item, editors may choose whether to capitalize what follows, taking into consideration the existing practice and consistency with related articles.

Except in technical usage (a 3:1 ratio), no sentence should contain multiple colons, no space should precede a colon, and a space (but never a hyphen or dash) should follow the colon.

Semicolons
A semicolon is sometimes an alternative to a full stop (period), enabling related material to be kept in the same sentence; it marks a more decisive division in a sentence than a comma. If the semicolon separates clauses, normally each clause must be independent (meaning that it could stand on its own as a sentence). In many cases, only a comma or only a semicolon will be correct in a given sentence.

Above, "Though he had been here before" cannot stand on its own as a sentence, and therefore is not an independent clause.

This incorrect use of a comma between two independent clauses is known as a comma splice; however, in certain kinds of cases, a comma may be used where a semicolon would seem to be called for:

A sentence may contain several semicolons, especially when the clauses are parallel in construction and meaning; multiple unrelated semicolons are often signs that the sentence should be divided into shorter sentences or otherwise refashioned.

Semicolons are used in addition to commas to separate items in a listing, when commas alone would result in confusion.

Semicolon before "however"
The meaning of a sentence containing a trailing clause that starts with the word however depends on the punctuation preceding that word. A common error is to use the wrong punctuation, thereby changing the meaning to one not intended.

When the word however is an adverb meaning "nevertheless", it should be preceded by a semicolon and followed by a comma. Example:

When the word however is a conjunction meaning "in whatever manner", or "regardless of how", it may be preceded by a comma but not by a semicolon, and should not be followed by punctuation. Example:

In the first case, the clause that starts with "however" cannot be swapped with the first clause; in the second case this can be done without change of meaning:

If the two clauses cannot be swapped, a semicolon is required.

A sentence or clause can also contain the word however in the middle, if it is an adverb meaning "although" that could have been placed at the beginning but does not start a new clause in mid-sentence. In this use, the word may be enclosed between commas. Example:

Hyphens
Hyphens (-) indicate conjunction. There are three main uses:


 * 1) In hyphenated personal names (John Lennard-Jones, Omar al-Bashir).
 * 2) To link prefixes with their main terms in certain constructions (quasi-scientific, pseudo-Apollodorus, ultra-nationalistic).
 * 3) *A hyphen may be used to distinguish between homographs (re-dress means dress again, but redress means remedy or set right).
 * 4) *There is a clear trend to join both elements in all varieties of English (subsection, nonlinear). Hyphenation clarifies when the letters brought into contact are the same (non-negotiable, sub-basement) or are vowels (pre-industrial), or where a word is uncommon (co-proposed, re-target) or may be misread (sub-era, not subera). Some words of these sorts are nevertheless common without the hyphen (e.g., cooperation is more frequently attested than in contemporary English).
 * 5) To link related terms in compound modifiers:
 * 6) *Hyphens can aid ease of reading (that is, they can be ease-of-reading aids) and are particularly useful in long noun phrases: gas-phase reaction dynamics. But never insert a hyphen into a proper name (Middle Eastern cuisine, not Middle-Eastern cuisine).
 * 7) *A hyphen can help to disambiguate (some short-story writers are quite tall; a government-monitoring program is a program that monitors the government, whereas a government monitoring program is a government program that monitors).
 * 8) *Compounds that are hyphenated when used (adjectives before the nouns they qualify: a light-blue handbag, a 34-year-old woman) or  (as a noun: she is a 34-year-old) are usually not hyphenated when used  (descriptive phrase separated from the noun: the handbag was light blue, the woman is 34 years old). Where there would otherwise be a loss of clarity, however, a hyphen may be used in the predicative form as well (hand-fed turkeys, the turkeys were hand-fed). Awkward attributive hyphenation can sometimes be avoided with a simple rewording: Hawaiian-native species → native Hawaiian species.
 * 9) *Avoid using a hyphen after a standard -ly adverb (a newly available home, a wholly owned subsidiary) unless part of a larger compound (a slowly-but-surely strategy). In rare cases, a hyphen can improve clarity if a rewritten alternative is awkward, but rewording is usually preferable: The idea was clearly stated enough can be disambiguated as The idea clearly was stated often enough or The idea was stated with enough clarity.
 * 10) *A few words ending in -ly function as both adjectives and adverbs (a kindly-looking teacher; a kindly provided facility). Some such dual-purpose words (like early, only, northerly) are not standard -ly adverbs, because they are not formed by addition of -ly to an independent current-English adjective. These need careful treatment: Early flowering plants appeared around 130 million years ago, but Early-flowering plants risk damage from winter frosts; only child actors (no adult actors) but only-child actors (actors without siblings).
 * 11) *A hyphen is normally used when the adverb well precedes a participle used attributively (a well-meaning gesture; but normally a very well managed firm, because well itself is modified) and even predicatively, if well is necessary to, or alters, the sense of the adjective rather than simply intensifying it (the gesture was well-meaning, the child was well-behaved, but the floor was well polished).
 * 12) *In some cases, such as diode–transistor logic, the independent status of the linked elements requires an en dash instead of a hyphen.
 * 13) *Use a suspended hyphen (also called a hanging hyphen) when two compound modifiers are separated (two- and three-digit numbers; a ten-car or -truck convoy; sloping right- or leftward).
 * 14) *Values and units used as compound modifiers are hyphenated only where the unit is given as a whole word; when using the unit symbol, separate it from the number with a non-breaking space.

Multi-word hyphenated items: It is often possible to avoid multi-word hyphenated modifiers by rewording (a four-CD soundtrack album may be easier to read as a soundtrack album of four CDs). This is particularly important where converted units are involved (the 6-hectare-limit (14.8-acre-limit) rule might be possible as the rule imposing a limit of six hectares (14.8 acres), and the ungainly 4.9-mile (7.9 km) -long tributary as simply 4.9-mile (7.9 km) tributary).

For optional hyphenation of compound points of the compass such as southwest/south-west, see.

Do not use a capital letter after a hyphen except for a proper name following the hyphen: Graeco-Roman and Mediterranean-style, but not Gandhi-Like. In titles of published works, when given in title case, follow the capitalization rule for each part independently (The Out-of-Towners), unless reliable sources consistently do otherwise in a particular case (The History of Middle-earth).

Hyphenation rules in other languages may be different. Thus, in French a place name such as Trois-Rivières ('Three Rivers') is hyphenated, when it would not be in English. Follow reliable sources in such cases.

Spacing: A hyphen is never followed or preceded by a space, except when hanging or when used to display parts of words independently, such as the prefix sub-and the suffix-less.

Image filenames and redirects: Image filenames are not part of the encyclopedic content; they are tools. They are most useful if they can be readily typed, so they usually use hyphens instead of dashes. Similarly, article titles with dashes should also have a corresponding redirect from a copy of the title with hyphens: for example, Michelson-Morley experiment redirects to Michelson–Morley experiment.

Non-breaking: A non-breaking hyphen will  be used as a point of line-wrap.

Soft hyphens: Use soft hyphens to mark locations where a word will be broken and hyphenated at the end of a line of text, usually in very long words or narrow spaces (such as captions, narrow table columns, or text adjacent to a very wide image), for example:. Use sparingly to avoid making wikitext difficult to read and edit. For more information, see Help:Line-break handling.

Encoding: The hyphen is represented by the ASCII/UNICODE HYPHEN-MINUS character, which is entered by the hyphen or minus key on all standard keyboards. Do not use the UNICODE HYPHEN character.

Hyphenation involves many subtleties that cannot be covered here; the rules and examples presented above illustrate the broad principles.

Dashes
Two forms of dash are used on Wikipedia: en dash (–) and em dash (—). To enter them, click on them in the CharInsert toolbar, or enter them manually as: Do not use a double hyphen to stand in for a dash.
 * or
 * or

Sources use dashes in varying ways. For consistency and clarity, Wikipedia adopts the following principles.

In article titles
In article titles, do not use a hyphen (-) as a substitute for an en dash, for example in eye–hand span (since eye does not modify hand). Nonetheless, to aid searching and linking, provide a redirect with hyphens replacing the en dash(es), as in eye-hand span. Similarly, provide category redirects for categories containing dashes. When an en dash is being used as a separator in an article title or section heading, editors may choose whether to capitalize what follows, taking into consideration the existing practice and consistency with related articles.

In running text
Dashes are often used to mark divisions within a sentence: in pairs (parenthetical dashes, instead of parentheses or pairs of commas) or singly (perhaps instead of a colon). They may also indicate an abrupt stop or interruption in reporting quoted speech. In all such cases, either unspaced em dashes or spaced en dashes can be used, with consistency maintained throughout a given article:
 * An em dash is unspaced on both sides:


 * An en dash is spaced on both sides:

Ideally, an en dash should be preceded by a non-breaking space; this prevents the dash from appearing at the beginning of a line. The template may be used for this:

Do not insert any spaces where an en dash should be unspaced.

Dashes can clarify a sentence's structure when commas, parentheses, or both are also being used.
 * The book summarizes works of some major philosophers in chronological order: Descartes, Locke, Hume – but not his Treatise (deemed too complex for the target audience) – and Kant.

Use dashes sparingly. More than two in a single sentence makes the structure unclear; it takes time for the reader to see which dashes form a pair, if any.
 * The birds – at least the ones Darwin collected – had red and blue feathers.
 * "We have run aground at – ", was the final, incomplete message received from the ship.
 * Avoid: First – at a marshy site leveled with landfill – came the workshop – then administrative and other buildings.
 * Better: First – at a marshy site leveled with landfill – came the workshop; administrative and other buildings were erected later.

In ranges that might otherwise be expressed with to or through
For ranges between numbers, dates, or times, use an en dash:
 * pp. 7–19;  64–75%;   Henry VIII reigned 1509–1547

Do not change hyphens to dashes in filenames, URLs, or templates such as (which formats verse ranges into URLs), even if a range is embedded in them.

Do not mix en dashes with between or from.
 * 450–500 people
 * between 450 and 500 people, not between 450–500 people
 * from 450 to 500 people, not from 450–500 people
 * from 1961 to 1964, not from 1961–1964
 * between the 1961–1962 and 1967–1968 seasons, ticket sales dropped substantially (or between the 1961–62 and 1967–68 seasons)

The en dash in a range is always unspaced, except when either or both elements of the range include at least one space, hyphen, or en dash; in such cases, snd between them will provide the proper formatting.
 * July 23, 1790 – December 1, 1791 (not July 23, 1790–December 1, 1791)
 * 14 May – 2 August 2011 (not 14 May–2 August 2011)
 * 1–17 September (and note in this case that the second element of the range is 17 not 17September);  February–October 2009;   1492 – 7 April 1556
 * Christmas Day – New Year's Eve;  Christmas 2001 – Easter 2002;   10:30 pm Tuesday – 1:25 am Wednesday;   6:00 p.m. – 9:30 p.m. (but 6:00–9:30 p.m.)
 * wavelengths in the range 28 mm – 17 m.
 * pages 5-7 – 5-9

If negative values are involved, an unspaced en dash might be confusing:
 * −10 to 10, not −10–10 (though −10 – 10 might work in a table consistently formatted with x–y constructions)

In compounds when the connection might otherwise be expressed with to, versus, and, or between
Here, the relationship is thought of as parallel, symmetric, equal, oppositional, or at least involving. The components may be nouns, adjectives, verbs, or any other independent part of speech. Often, if the components are reversed there would be little change of meaning.
 * boyfriend–girlfriend problems;  the Paris–Montpellier route;   a New York–Los Angeles flight
 * iron–cobalt interactions; the components are parallel and reversible; iron and cobalt retain their identity
 * Wrong: an iron–roof shed; iron modifies roof, so use a hyphen: an iron-roof shed
 * Wrong: a singer–songwriter; not separate persons, so use a hyphen: a singer-songwriter
 * red–green colorblind; red and green are separate independent colors, not mixed
 * Wrong: blue–green algae; a blended, intermediate color, so use a hyphen: blue-green algae
 * a 51–30 win;  a 12–0 perfect season;   a 22–17 majority vote; but prefer spelling out when using words instead of numerals: a six-to-two majority decision, not with the awkward six–two;  avoid confusingly reversed order: a 17–22 majority vote
 * a 50–50 joint venture;  a 60–40 split;   avoid using a slash (stroke) here, which indicates division
 * the Uganda–Tanzania War;  the Roman–Syrian War;   the east–west runway;   the Lincoln–Douglas debates;   a carbon–carbon bond
 * diode–transistor logic;  the analog–digital distinction;   push–pull output;   on–off switch
 * a pro-establishment–anti-intellectual alliance;  Singapore–Sumatra–Java shipping lanes
 * the ballerina's rapid walk–dance transitions;  a male–female height ratio of 1.14

Generally, use a hyphen in compounded proper names of single entities.
 * Guinea-Bissau; Bissau is its capital, and this name distinguishes the country from neighboring Guinea
 * Wilkes-Barre, a single city named after two people, but Minneapolis–Saint Paul, an area encompassing two cities
 * John Lennard-Jones, an individual named after two families

Use an en dash between the names of nations or nationalities when referring to an association between them. For people and things identifying with multiple nationalities, use a hyphen when using the combination adjectivally and a space when they are used as nouns, with the first used attributively to modify the second.
 * an Italian–Swiss border crossing;  but an Italian-Swiss newspaper for Italian-speaking Swiss
 * France–Britain rivalry;  French–British rivalry
 * an Indian-American scientist;  was especially popular with Indian Americans
 * Wrong: Franco–British rivalry; Franco- is a, not an independent word, so use a hyphen: Franco-British rivalry

A slash or some other alternative may occasionally be better to express a ratio, especially in technical contexts.
 * the protein–fat ratio;  the protein/fat ratio;   the protein-to-fat ratio
 * Colons are often used for strictly numeric ratios, to avoid confusion with subtraction and division: a 3:1 ratio; a three-to-one ratio.

Use an en dash for the names of two or more entities in an attributive compound.
 * the Seifert–van Kampen theorem;  the Alpher–Bethe–Gamow theory
 * the Seeliger–Donker-Voet scheme (developed by Seeliger and Donker-Voet)
 * Comet Hale–Bopp or just Hale–Bopp (discovered by Hale and Bopp)

Do not use an en dash for hyphenated personal names, even when they are used as adjectives:
 * Lennard-Jones potential with a hyphen: named after John Lennard-Jones

Do not use spaces around the en dash in any of the compounds above.

Instead of a hyphen, use an en dash when applying a prefix or suffix to a compound that itself includes a space, dash or hyphen

 * ex–prime minister Thatcher (consider recasting: former prime minister Thatcher)
 * pre–World War II aircraft (consider recasting: aircraft from before World War II)
 * post–September 11 anti-war movement
 * Trans–New Guinea languages


 * Turks and Caicos–based company
 * a Rodgers and Hammerstein–esque musical number

The form of category names follows the corresponding main articles, e.g.,. However, the principle is not extended when compounding other words in category names, e.g., and  both use hyphens.

To separate parts of an item in a list
Spaced en dashes are sometimes used between parts of list items. For example: or
 * James Galway – flute; Anne-Sophie Mutter – violin; Maurizio Pollini – piano.
 * "The Future" – 7:21
 * "Ain't No Cure for Love" – 6:17
 * "Bird on the Wire" – 6:14

Editors may choose whether to capitalize what follows, taking into consideration the existing practice and consistency with related articles.

Other uses for en dashes
The en dash (–) has several common functions beyond its use in lists and running text. It is used to join components less strongly than a hyphen would ; conversely, it may also separate components less strongly than a slash would. Consider the relationship that exists between two components when deciding what punctuation to place between them.

Other uses for em dashes
An indented em dash may be used when attributing the source of a passage, such as a block quotation or poem. This dash should not be fully spaced: however, for reasons related to metadata and accessibility, it is best to place a hair space between the dash and the name. Most of Wikipedia's quotation templates provide this formatting automatically.

For example, —hair spaceCharlotte Brontë will produce:

— Charlotte Brontë

Other dashes
Do not use typewriter approximations or other substitutes, such as two hyphens (--), for em or en dashes.

For a negative sign or subtraction operator use, which can also be generated by clicking on the − following the ± in the Insert toolbar beneath the edit window. Do not use inside a  tag, as the character gives a syntax error; instead use a normal hyphen.

Slashes (strokes)
Generally, avoid joining two words with a slash, also called a forward slash, stroke or solidus (/), because it suggests that the words are related without specifying how. Replace with clearer wording.

An example: The parent/instructor must be present at all times. Must both be present? (Then write the parent and the instructor.) Must at least one be present? (Then write the parent or the instructor.) Are they the same person? (Use a hyphen: the parent-instructor.)

In circumstances involving a distinction or disjunction, the en dash is usually preferable to the slash: the digital–analog distinction.

An unspaced slash may be used:
 * to indicate phonemic pronunciations (rivet is pronounced);
 * in a fraction (, but see other techniques at );
 * to indicate regular defined yearly periods that do not coincide with calendar years (e.g., the 2009/2010 fiscal year), if that is the convention used in reliable sources (see for further explanation);
 * to express a ratio, in a form in which a slash is conventionally used (e.g., the price-to-earnings ratio, or P/E ratio for short);
 * in an expression or abbreviation widely used outside Wikipedia (e.g., n/a or N/A for not applicable).

A spaced slash may be used:
 * to separate run-on lines in quoted poetry or song (To be or not to be: that is the question: / Whether 'tis nobler in the mind to suffer / The slings and arrows of outrageous fortune), or rarely in quoted prose, where careful marking of a paragraph break is textually important;
 * to separate items that include at least one internal space (the NY 31 east / NY 370 exit), where for some reason use of a slash is unavoidable.

To avoid awkward linebreaks, code spaced slashes (and fraction slashes) with a non-breaking space on the left and a normal space on the right, as in:. For short constructions, both spaces should be non-breaking:. On the other hand, if two long words are connected by an unspaced slash, an wbr added after the slash will allow a linebreak at that point.

Do not use the backslash character (\) in place of a slash.

Prefer the division operator (÷) to slash or fraction slash when representing elementary arithmetic in general text: 10 ÷ 2 = 5. In more advanced mathematical formulas, a vinculum or slash is preferred: $$\textstyle\frac{x^n}{n!}$$ or xn/n! .

And/or
Avoid writing and/or unless other constructions would be lengthy or awkward. Instead of Most had trauma and/or smoke inhalation, write simply trauma or smoke inhalation (which would normally be interpreted as an inclusive-or to imply or both); or, for emphasis or precision or both, write trauma or smoke inhalation or both. Where more than two possibilities are present, instead of x, y, and/orz write one or more of x, y, andz or some or all of x, y, andz.

Symbols
Unicode symbols are preferred over composed ASCII symbols for improved readability and accessibility. Be mindful of presentations that may require ASCII, like sourcecode. Keys for these symbols can be found at the bottom of the Source Editor.

Number (pound, hash) sign and numero
Avoid using the # symbol (known as the number sign, hash sign, pound sign, or octothorpe) when referring to numbers or rankings. Instead write number, No. or Nos.; do not use the symbol №. For example:

An exception is issue numbers of comic books, which unlike for other periodicals are conventionally given in general text in the form #1, unless a volume is also given, in which case write volume two, number seven or Vol. 2, No. 7. Another exception are periodical publications carrying both, issue and number designations (typically one being a year-relative and the other an absolute value); they should be given in the form 2 #143 in citations, or be spelt out as Iss. 2, No. 143 in text. When using the abbreviations, write, , , or , at first occurrence.

Terminal punctuation

 * Exclamation and question marks have almost no application in encyclopedic writing.
 * For the use of three periods in succession, see.
 * In some contexts, no terminal punctuation is necessary. In such cases, the sentence often does not start with a capital letter. See and.
 * Sentence fragments in captions or lists should in most cases not end with a period. See and.

Spacing
In normal text, never put a space before a comma, semicolon, colon, period/full stop, question mark, or exclamation mark (even in quoted material; see ).

Some editors place two spaces after a period/full stop ; these are condensed to one space when the page is rendered, so it does not affect what readers see.

Consecutive punctuation marks
Where a word or phrase that includes terminal punctuation ends a sentence, do not add a second terminal punctuation mark. If a quoted phrase or title ends in a question mark or exclamation mark, it may confuse readers as to the nature of the article sentence containing it, and so is usually better reworded to be mid-sentence. Where such a word or phrase occurs mid-sentence, new terminal punctuation (usually a period) must be added at the end.

Punctuation and footnotes
Reference tags (<ref ></ref>) are used to create footnotes (also called endnotes or simply notes), as citation footnotes and sometimes explanatory notes. All reference tags should immediately follow the text to which the footnote applies, with no intervening space. Apart from the exceptions listed below, references are placed after adjacent punctuation, not before. Adjacent reference tags should have no space between them, nor should there be any between tags and inline dispute and cleanup templates.

When reference tags are used, a footnote list must be added, and this is usually placed in the References section, near the end of the article in the standard appendices and footers.


 * Example : Flightless birds have a reduced keel, and they also have smaller wing bones than flying birds of similar size.

Exceptions: Reference tags are placed before dashes, not after. If a footnote applies only to material within parentheses, the tags belong just before the closing parenthesis.
 * Example : Paris is not the capital city of England – the capital of which is London – but that of France.
 * Example : Kim Jong-un (Korean: 김정은; Hanja: 金正恩) is the Supreme Leader of North Korea.

Punctuation after formulae
Sentences should place punctuation after mathematical formulae as if they were normal body text. See.

Dates and time
Dates should be linked only when they are germane and topical to the subject, as discussed at. For ranges of dates and times, see.

Time of day
Times of day are normally expressed in figures rather than words. Context determines whether the 12- or the 24-hour format is more appropriate.
 * Twelve-hour clock times are written in one of two forms: 11:15 a.m. and 2:30 p.m., or 11:15 am and 2:30 pm (wherein the spaces should be non-breaking). Use noon and midnight rather than 12 pm and 12 am; it may need to be specified whether midnight refers to the start or end of a date.
 * Twenty-four-hour clock times are written in the form 08:15 and 22:55, with no suffix. Midnight written as 00:00 begins the day; 24:00 ends it.

Dates
Full dates are formatted 10 June 1921 or June 10, 1921; or where the year is omitted, use 10 June or June 10.
 * The dates in the text of any one article should all have the same format (day-first or month-first).
 * For date formats in citations, see.
 * Dates in quotations and titles are always left as-is.
 * If a numerical format is required (e.g., for conciseness in lists and tables), use the YYYY-MM-DD format: 2005-04-03.
 * Articles on topics with strong ties to a particular English-speaking country should generally use the more common date format for that country (month-first for the US, except in military usage; day-first for most others; articles related to Canada may use either consistently). Otherwise, do not change an article from one date format to the other without good reason.

Months

 * For month and year, write June 1921, with no comma.
 * Abbreviations for months, such as Feb, are used only where space is extremely limited. Such abbreviations should use three letters only, and should not be followed by a period (full point) except at the end of a sentence.

Seasons

 * Avoid ambiguous references to seasons, which are different in the southern and northern hemispheres.
 * Names of seasons may be used when there is a logical connection to the event being described (the autumn harvest) or when referring to a phase of a natural yearly cycle (migration typically starts in mid-spring). Otherwise, neutral wording is usually preferable (He was elected in November 1992, not He was elected in the fall of 1992).
 * Journals and other publications that are issued seasonally (e.g., "Summer 2005") should be dated as such in citations.

Years and longer periods

 * Do not use the year before the digits (1995, not the year 1995), unless the meaning would otherwise be unclear.
 * Decades are written in the format the 1980s, with no apostrophe. Use the two-digit form ('80s) only with an established social or cultural meaning. Avoid forms such as the 1700s that could refer to ten or a hundred years.
 * Years are denoted by AD and BC or, equivalently, CE and BCE. Use only one system within an article, and do not change from one system to the other without good reason. The abbreviations are written without periods, and with a non-breaking space, as in 5 BC. Omit AD or CE unless omitting it would cause ambiguity.

More information on all the above topics can be found at, including the handling of dates expressed in different calendars, and times corresponding to different time zones.

Current
Terms such as "current", "now", and "recent" should be avoided. What is current today may not be tomorrow; situations change over time. Instead, use date- and time-specific text. To help keep information updated use, which will allow editors to catalog and update dated statements.

Numbers

 * Integers from zero to nine are spelled out in words. Integers greater than nine may be expressed either in numerals or in words. Other numbers are given in numerals or in forms such as 21million. See.
 * In general, in numbers with five or more digits to the left of the decimal point, use commas to group those digits. Numbers with four digits are at the editor's discretion: 12,345, but either 1,000 or 1000. See.
 * In general, use decimals rather than fractions for measurements, but fractions are sometimes used with imperial and U.S. customary units. Keep articles internally consistent.
 * Scientific notation (e.g., $5.8 kg$) is preferred in scientific contexts. Markup:.
 * Write out "million" and "billion" on the first use. After that, unspaced "M" can be used for millions and "bn" for billions: 70M and 25bn. See for similar words.
 * Write 3%, three percent, or three per cent, but not 3% (with a space) or three%. "Percent" is American usage, and "per cent" is British usage . In ranges of percentages written with an en dash, write only a single percent sign: 3–14%.
 * Indicate uncertainties as e.g., $5.8 kg$. Markup: . See  for other formats.

Currencies

 * Use the full abbreviation on first use (US$ for the US dollar and A$ for the Australian dollar), . For example, the government of the United States always spends money in American dollars, and never in Canadian or Australian dollars.
 * Use only one symbol with ranges, as in $250–300.
 * In articles that are not specific to a country, express amounts of money in United States dollars, euros, or pounds sterling. Do not link the names or symbols of currencies that are commonly known to English-speakers ($, €, £), unless there is a particular reason to do so; do not use potentially ambiguous currency symbols, unless the meaning is clear in the context.
 * In country-specific articles, use the currency of the country. On first occurrence, consider including conversion to US dollars, euros, or pounds sterling, at a rate appropriate to the context. For example, Since 2001 the grant has been 10,000,000 Swedish kronor (€1.0M as of August 2009). Wording such as "approx." is not appropriate for simple rounding-off of the converted amount.
 * Generally, use the full name of a currency, and link it on its first appearance if English-speakers are likely to be unfamiliar with it (52 Nepalese rupees); subsequent occurrences can use the currency sign (just 88 Rs).
 * Most currency symbols are placed the number, and unspaced ($123 not $ 123).

Units of measurement

 * The main unit in which a quantity is expressed should generally be an SI unit or non-SI unit officially accepted for use with the SI. However,
 * Scientific articles may also use specialist units appropriate for the branch of science in question.
 * In non-scientific articles with strong ties to the United States, the main unit is generally a U.S. customary unit (22 pounds (10 kg)).
 * In non-scientific articles with strong ties to the United Kingdom, although the main unit is generally a metric unit (10 kilograms (22 lb)), imperial units are still used as the main units in some contexts (7 miles (11 km) by road).
 * Where English-speaking countries use different units for the same measurement, provide a conversion in parentheses. Examples: the Mississippi River is 2320 mi long; the Murray River is 2375 km long. See.
 * In a direct quotation, always retain the source's units. Any conversion should follow in square brackets (or, an obscure use of units can be explained in the article text or a footnote).
 * Where space is limited (such as tables, infoboxes, parenthetical notes, and mathematical formulas) unit symbols are preferred. In prose, unit names should be given in full if used only a few times but symbols may be used when a unit (especially one with a long name) is used repeatedly after spelling out the first use (e.g., Up to 15 kilograms of filler is used for a batch of 250kg), except for unit names that are hardly ever spelled out (°C rather than degrees Celsius).
 * Most unit names are not capitalized (see for spelling differences).
 * Use "per" when writing out a unit, rather than a slash: metre per second, not metre/second.
 * Units unfamiliar to general readers should be presented as a name–symbol pair on first use, linking the unit name (Energies were originally 2.3 megaelectronvolts (MeV), but were eventually 6MeV).
 * For ranges, see, and MOS:NUM, at.
 * Unit symbols are preceded by figures, not by spelled-out numbers. Values and unit symbols are separated by a non-breaking space. For example, 5 min. The percent sign and units of degrees, minutes, and seconds are unspaced.

Common mathematical symbols

 * For a negative sign or subtraction operator, use a minus sign (−, Unicode character U+2212 MINUS SIGN ). Input by clicking on it in the insert box beneath the edit window or by typing.
 * For multiplication, use a multiplication sign or a dot, which are input by clicking on them in the edit toolbox under the edit window or by entering   or  . Care should be taken not to confuse the dot operator (in the "Math and logic" section of the edit toolbox) with an interpunct (in the "Insert" section of the edit toolbox) or a bullet. The letter x should not be used to indicate multiplication, but it is used (unspaced) as the substitute for "by" in terms such as 4x4.
 * Exponentiation is indicated by a superscript, an (typed as.
 * Do not use programming language notation outside computer program text. In most programming languages, subtraction, multiplication, and exponentiation are represented by the hyphen-minus, the asterisk  , and either the caret   or the double asterisk  ; scientific notation is replaced by E notation.
 * Symbols for binary operators and relations are usually spaced on both sides:
 * plus, minus, and plus-or-minus (as binary operators): +, −, ± (as in 5 − 3);
 * multiplication and division: ×, ÷;
 * equals, does not equal, equals approximately: =, ≠, ≈;
 * is less than, is less than or equal to, is greater than, is greater than or equal to: <, ≤, >, ≥.
 * Symbols for unary operators are closed-up to their operand:
 * positive, negative, and positive-or-negative signs: +, −, ± (as in −3);
 * other unary operators, such as the exclamation mark as a factorial sign (as in 5!).
 * Variables are italicized, but digits and punctuation are not; only x and y are italicized in 2(5x + y)2.
 * can be used to style formulas to distinguish them from surrounding text. For single variables, is handy.

Singular nouns
For the possessive of singular nouns, including proper names and words ending in s, add &apos;s (my daughter's achievement, my niece's wedding, Cortez's men, the boss's office, Illinois's largest employer, the US's partners, Descartes's philosophy, Verreaux's eagle). Exception: abstract nouns ending with an /s/ sound when followed by sake (for goodness' sake, for his conscience' sake). If a name ending in s or z would be difficult to pronounce with &apos;s added (Jesus's teachings), consider rewording (the teachings of Jesus).

Plural nouns

 * For a normal plural noun ending with a pronounced s, form the possessive by adding just an apostrophe (my sons' wives, my nieces' weddings).
 * For a plural noun ending with a pronounced s, add  's (women's careers, people's habits, mice's whiskers; The two Dumas's careers were controversial, but where rewording is an option, this may be better: The career of each Dumas was controversial).

Official names
Official names (of companies, organizations, or places) should not be altered. (St Thomas' Hospital should therefore be rendered as St Thomas's Hospital or St. Thomas Hospital, even for consistency.)

First-person pronouns
To maintain an objective and impersonal encyclopedic voice, an article should never refer to its editors or readers using I, my, we, us, our, or similar words: We note that some believe that bats are bugs. But some of these words are acceptable in certain figurative uses. For example:
 * In historical articles to mean the modern world as a whole: Only portions of De re publica have come down to us.
 * The author's we found in scientific writing (We construct $1.534 m$ as follows), though passive voice may be preferable ($1.534 m$ is constructed as follows).

Second-person pronouns
Avoid addressing the reader using you or your, which sets an inappropriate tone.
 * Use a noun or a third-person pronoun: instead of When you move past "Go", you collect $200, use A player passing "Go" collects $200, or When a player passes "Go", they collect $200.
 * If a person cannot be specified, or when implying "anyone" as a subject, the impersonal pronoun one may be used: a sense that one is being watched. Other constructions may be preferable if the pronoun one seems stilted: a person's sense of being watched.
 * The passive voice may sometimes be used instead: Impurities are removed before bottling.
 * Do not bait links, e.g., "Click here for more information"; let the browser's normal highlighting invite a click. ("Click here" also makes no sense to someone reading on paper.)
 * Likewise, "See: (reference)" or "Consider ..." are milder second-person baits, common in academic writing (pedagogy). This interactive personality is inconsistent with an encyclopedia's passive presentation of objective matter.
 * "See" and the like can be used to internally cross-reference other Wikipedia material. Do not italicize words like "see". Such a cross reference should be parenthetical, so the article text stands alone if the parenthetical is removed. can be used for this:,  It is usually better to rewrite the material to integrate these links contextually rather than use explicit Wikipedia self-references.
 * Do not address the reader with the Socratic method by asking and answering questions. Did Bacon write Shakespeare? Then who wrote Bacon?

Plurals
Use the appropriate plural; allow for cases (such as excursus or hanif) in which a word is now listed in major English dictionaries, and normally takes an s or es plural, not its original plural: two excursuses, not two excursūs as in Latin; three hanifs, not three hunafa as in Arabic.

Some collective nouns – such as team (and proper names of them), army, company, crowd, fleet, government, majority, mess, number, pack, and party – may refer either to a single entity or to the members that compose it. In British English, such words are sometimes treated as singular, but more often treated as plural, according to context (but singular is not actually ). In North American English, these words are almost invariably treated as singular; the major exception is that when a sports team is referred to by its short name, plural verbs are commonly used, e.g. the Heat are playing the Lakers tonight.

Names of towns and countries usually take singular verbs (even when grammatically plural: the United States is in North America, the Netherlands is also known as Holland), but exceptionally in British English, typically when used to refer to a sports team named after a town or country or when discussing actions of a government, plural is used. For example, in England are playing Germany tomorrow, England refers to a football team; but in England is in the Northern hemisphere, it refers to the country. See also including.

Verb tense
By default, write articles in the present tense, including those covering works of fiction and products or works that have been discontinued. Generally, use past tense only for past events, and for subjects that are dead or no longer meaningfully exist. Use past tense for articles about periodicals no longer produced, with common-sense exceptions.
 * The PDP-10 is a mainframe computer family manufactured by Digital Equipment Corporation from 1966 into the 1980s.
 * Earth: Final Conflict is a Canadian science fiction television series that ran for five seasons between October 6, 1997, and May 20, 2002.
 * The Gordon Riots of 1780 were...
 * The Beatles were an English rock band that formed in Liverpool in 1960.
 * Barack Obama is a former president of the United States (not Barack Obama was a president of the United States).
 * Jumbo Comics was an adventure anthology comic book published by Fiction House from 1938 to 1953.
 * A Prairie Home Companion is a radio show that aired live from 1974 to 2016 (not A Prairie Home Companion was a radio show).
 * Flappy Bird is a mobile game developed by Vietnamese video game artist and programmer Dong Nguyen (not Flappy Bird was a mobile game).

Tense can be used to distinguish between current and former status of a subject: Dún Aonghasa the ruin of a prehistoric Irish cliff fort. Its original shape presumably oval or D-shaped, but parts of the cliff and fort have since collapsed into the sea. (Emphasis added to distinguish the different tense usages; Dún Aonghasa is a structure that was later damaged by an event.)

Always use present tense for verbs that describe genres, types, and classes, even if the subject of the description (e.g. program, library, device) no longer exists, is discontinued, or is unsupported/unmaintained.

Contractions
Avoid contractions, which have little place in formal writing. For example, write do not instead of don't. Use of o'clock is an exception. Contracted titles such as Dr. and St generally should not be used but may apply in some contexts (e.g., quoted material, place names, titles of works).

Gender-neutral language
Use gender-neutral language – avoiding the generic he, for example – if this can be done with clarity and precision. This does not apply to direct quotations or the titles of works (The Ascent of Man), which should not be altered, or to wording about one-gender contexts, such as an all-female school (When any student breaks that rule, she loses privileges).

References to space programs, past, present and future, should use gender-neutral phrasing: human spaceflight, robotic probe, uncrewed mission, crewed spacecraft, piloted, unpiloted, astronaut, cosmonaut, not manned or unmanned. Direct quotations and proper nouns that use gendered words should not be changed, like Manned Maneuvering Unit.

Ships may be referred to using either neuter forms ("it", "its") or feminine forms ("she", "her", "hers"). Either usage is acceptable, but each article should be internally consistent and employ one or the other exclusively. As with all optional styles, articles should not be changed from one style to another unless there is a substantial reason to do so. See.

Contested vocabulary
Avoid words and phrases that give the impression of straining for formality, that are unnecessarily regional, or that are not widely accepted. See List of commonly misused English words; see also.

Instructional and presumptuous language
Avoid phrases such as remember that and note that, which address readers directly in an unencyclopedic tone and lean toward instructional. They are a subtle form of Wikipedia self-reference, "breaking the fourth wall". Similarly, phrases such as of course, naturally, obviously, clearly, and actually make presumptions about readers' knowledge, may express a viewpoint, and may call into question the reason for including the information in the first place. Do not readers that something is interesting, ironic, surprising, unexpected, amusing, coincidental, etc. Simply present sourced facts neutrally and let readers draw their own conclusions. Such constructions can usually just be deleted, leaving behind proper sentences with a more academic and less pushy tone: Note that this was naturally subject to controversy in more conservative newspapers. becomes This was subject to controversy in more conservative newspapers. Similar variants which indirectly instruct readers, such as It should be noted that or It is important to note that, may be rewritten by leaving out those words: It is important to note that the colloquial dialect of Portuñol is similar to but different from Mirandese becomes just The colloquial dialect of Portuñol is similar to but different from Mirandese.

Avoid rhetorical questions, especially in headings. Use a heading of Active listening and text such as The term active listening, coined in ..., not What is active listening?

For issues in the use of cross-references – e.g., ) – see.

Subset terms
A subset term identifies a set of members of a larger class. Common subset terms are including, among, and etc. Avoid redundant subset terms (e.g., mis-constructions like the most well-known members of the fraternity are two members of the Onassis family or The elements in stars hydrogen, helium,). The word including does not introduce a complete list; instead, use consisting of, or composed of.

Identity
When there is a discrepancy between the term most commonly used by reliable sources for a person or group and the term that person or group uses for themselves, use the term that is most commonly used by recent reliable sources. If it is unclear which is most used, use the term that the person or group uses.

Disputes over how to refer to a person or group are addressed by Wikipedia content policies, such as those on verifiability, and neutral point of view (and article titles when the term appears in the title of an article).

Use specific terminology. For example, it is often more appropriate for people or things from Ethiopia (a country in Africa) to be described as Ethiopian, not carelessly (with the risk of stereotyping) as African.

Gender identity
Specific guidelines apply to any person whose gender might be questioned, and any living transgender or non-binary person. In summary:
 * Use gendered words only if they reflect the person's latest self-identification as reported in recent sources.
 * If the person is living and was not notable yet when a former name was in use, that name should not be included in any Wikipedia page, even in quotations, as a privacy matter. Exception: Do not expunge or replace names in source citations (whether as authors or mentioned in work titles).
 * Former names under which a living person was notable should be introduced with "born" or "formerly" in the lead sentence of their main biographical article. Name and gender matters should be explained at first appearance in that article, without overemphasis. In articles on works or other activities of such a person, use their current name by default, and give another name associated with that context in a parenthetical or footnote, only if they were notable under that name. In other articles, do not go into detail about such a person's name or gender except when directly relevant to the context.
 * Avoid confusing constructions by rewriting. Paraphrase, elide, or use square brackets to replace portions of quotations as needed to avoid confusion, former names, and mismatching gendered words.

Terms without common usage in English
Non-English terms should be used sparingly. In general, use italics for phrases and words that are not current in English. This is best done with the template using the appropriate ISO language code, e.g.,. There are alternatives to the template which also provide additional information about a foreign word or phrase, such as a link to the language name;. As Wikipedia does not apply italics to names of people, places, or organizations, the alternative template can be used to apply the language markup without italicizing. Templates like automatically italicize text written using the Latin alphabet, so specifying italics is unnecessary.

Text written in non-Latin scripts such as Greek, Cyrillic, and Chinese should not be italicized or put in bold, as the difference in script is already sufficient to visually distinguish the text. In general, any non-Latin text should include an appropriate romanization.

Terms with common usage in English
Loanwords and borrowed phrases that have common usage in English – Gestapo, samurai, vice versa – do not require italics. A rule of thumb is to not italicize words that appear in major general-purpose English dictionaries.

Spelling and romanization
Names and terms originally written using a non-Latin script—such as the Greek alphabet, the Cyrillic alphabet, or Chinese characters—must be romanized for English-language use. If a particular romanization of the subject's name is most common in English (Tchaikovsky, Chiang Kai-shek), that form should be used. Otherwise, the romanization of names should adhere to a particular widely used system for the language in question (Aleksandr Tymoczko, Wang Yanhong).

The use of diacritics in non-English words is neither encouraged nor discouraged. Use generally depends on whether they appear in reliable English-language sources, though with some additional constraints imposed by site guidelines. Provide redirects from alternative forms that include or exclude diacritics.

Proper names in languages written using the Latin alphabet can include letters with diacritics, ligatures, and other characters that are not commonly used in contemporary English. Wikipedia normally retains these special characters, except where there is a well-established English spelling that replaces them with English standard letters. Examples: Use of diacritics is determined on a topic-by-topic basis; a small group of editors cannot prohibit or require the use of diacritics within a given class of articles.
 * The name of the article on Hungarian mathematician Paul Erdős is spelt with the double acute accent, and the alternative spellings Paul Erdos and Paul Erdös redirect to that article.
 * Similarly, the name of the article on the Nordic god Ægir is so spelt, with redirects from the ligature-free form Aegir and the Swedish spelling Ägir.
 * However, the region of Spain named Aragón in Spanish and Aragó in Catalan is given as Aragon, without the accent, as this is the established English name. Non-English forms with diacritics appear in the article's lead section.

Spell a name consistently in the title and the text of an article. For a non-English name, phrase, or word, adopt the spelling most commonly used in English-language reliable sources, including but not limited to those already cited in the article. For punctuation of compounded forms, see relevant guidelines in.

Proper names in non-English languages should generally not be italicized, unless another reason applies; such as with titles of major published works, e.g., Les Liaisons dangereuses; or when being compared to other names for the same subject in a words-as-words manner, e.g., Nuremberg (Nürnberg). When non-English text should not be italicized, it can still be properly tagged by using the template with the unset parameter:.

Sometimes usage will be influenced by other guidelines, such as, which may lead to different choices in different articles.

Other non-English concerns

 * For non-English vernacular names of species, see.
 * For handling of quotations in languages other than English, see.
 * For non-English characters that resemble single quotation marks and apostrophes, see.
 * For actual non-English quotation characters, see.
 * For the capitalization in the titles of non-English language works, see.
 * For linear and interlinear glosses and their particular uses of small-caps (and italics and single quotes), see.

Technical language
Some topics are necessarily technical: however, editors should seek to write articles accessible to the greatest possible number of readers. Minimize the use of jargon, and adequately explain its meaning when it is used. Overly technical material can be tagged with or, so that it can be addressed by other editors. For topics that require a more technical approach, the creation of a separate introductory article (like Introduction to general relativity) may be a solution.

Excessive wikilinking (linking within Wikipedia) can result from trying too hard to avoid putting explanations in parenthetical statements, like the one that appeared earlier in this sentence. Do not introduce specialized words simply to teach them to the reader when more widely understood alternatives will do.

When the concepts underlying the jargon used in an article are too complex to explain concisely in a parenthetical, write one level down. For example, consider adding a brief background section with tags pointing to articles with a fuller treatment of the prerequisite material. This approach is practical only when the prerequisite concepts are central to the exposition of the article's main topic and when such prerequisites are not too numerous. Short articles, such as stubs, generally do not have such sections.

Geographical items
<section begin="MOS:GEO" />Geographical or place names are the nouns used to refer to specific places and geographic features. These names often give rise to conflict, because the same places are called different things by different peoples speaking different languages. Many place names have a historical context that should be preserved, but common sense should prevail. There can be few places that have not been parts of more than one culture or have had only one name. As proper nouns, all such place names (but not terms for types of places) have major words capitalized.

A place should generally be referred to consistently by the same name as in the title of its article. An exception may be made when there is a widely accepted historical English name appropriate to the given context. In cases where such a historical name is used, it should be followed by the modern name in round brackets (parentheses) on the first occurrence of the name in applicable sections of the article. This resembles linking; it should not be done to the detriment of style. On the other hand, it is probably better to provide such a variant too often than too rarely. If more than one historical name is applicable for a given context, the other names should be added after the modern English name, that is: "historical name (modern name, other historical names)".

This is an English-language encyclopedia, so established English names are preferred if they exist, and spellings in non-English alphabets should always be transcribed into the Roman alphabet. In general, other articles should refer to places by the names which are used in the articles on those places, according to the rules described at Naming conventions (geographic names). If a different name is appropriate in a given historical or other context, then that may be used instead, although it is normal to follow the first occurrence of such a name with the standard modern name in parentheses.

At the start of an article, provide notable equivalent names from other languages, including transcriptions where necessary:
 * Cologne (Köln, IPA: ) is the ...
 * Mount Fuji (富士山, IPA: ) is the ...

Names in languages with no particular present-day or historical ties to the place in question (English excepted, of course) should be listed as alternatives.

Avoid anachronism. An article about Junípero Serra should say he lived in Alta Mexico, not in California, because the latter entity did not yet exist in Serra's time. The Romans invaded Gaul, not France, and Thabo Mbeki was the president of the Republic of South Africa, not of the Cape Colony. To be clear, you may sometimes need to mention the current name of the area (for example "in what is now France"), especially if no English name exists for that area in the relevant historical period.<section end="MOS:GEO" />

Images

 * Each image should be inside the level2 section to which it relates, within the section defined by the most recent  delimited by two equal signs, or at the top of the lead section. Do not place images immediately above section headings.
 * Avoid sandwiching text horizontally between two images that face each other, and between an image and an infobox or similar.
 * It is often preferable to place images of people so they "look" toward the text. Do not achieve this by reversing the image.
 * Any galleries should comply with . Consider linking to additional images on Commons instead.
 * Avoid referring to images as being to the left, the right, above or below, because image placement varies with platform, and is meaningless to people using screen readers; instead, use captions to identify images.
 * An image's alt text takes the image's place for those who are unable to see the image. See Manual of Style/Accessibility/Alternative text for images.

Other media
Style guidelines for still images are generally also applicable to equivalent questions regarding the use of audio and video media.

Avoid using images to display text
Textual information should always be transmitted as text, rather than in an image. True text can be easily searched, selected, copied, and manipulated by readers; its presentation can also be adjusted using CSS. These tasks are generally difficult or impossible with text presented in an image: images are slower to download, and generally cannot be searched or processed by screen readers used by the visually impaired. Any important textual information in an image should be provided somewhere as text, generally either in the image's caption or alt text.

For entering textual information as audio, see WikiProject Spoken Wikipedia.

Captions
Photographs and other graphics should have captions, unless they are unambiguous depictions of the subject of the article or when they are "self-captioning" images (such as reproductions of album or book covers). In a biography article no caption is necessary for a portrait of the subject pictured alone, but one might be used to give the year, the subject's age, or other circumstances of the portrait along with the name of the subject.

Formatting of captions

 * Captions normally start with a capital letter.
 * Most captions are not complete sentences but merely sentence fragments which should not end with a period. However, if any complete sentence occurs in a caption, then every sentence and every sentence fragment in that caption should end with a period.
 * The text of captions should not be specially formatted, except in ways that would apply if it occurred in the main text (e.g., italics for the Latin name of a species).
 * Captions should be succinct; more information can be included on its description page, or in the main text.
 * Captions for technical charts and diagrams may need to be substantially longer than usual; they should fully describe all elements of the image and indicate its significance.

Bulleted and numbered lists

 * Do not use lists if a passage is read easily as plain paragraphs.
 * Use proper wiki markup- or template-based list code.
 * Do not leave blank lines between items in a bulleted or numbered list unless there is a reason to do so, since this causes the Wiki software to interpret each item as beginning a new list.
 * Indents (such as this) are permitted if the elements are "child" items.
 * Use numbers rather than bullets only if:
 * a need to refer to the elements by number may arise;
 * the sequence of the items is critical; or
 * the numbering has some independent meaning, for example in a listing of musical tracks.
 * Use the same grammatical form for all elements in a list, and do not mix sentences and sentence fragments as elements, for example when the elements are:
 * complete sentences – each one is formatted with sentence case (its first letter is capitalized) and a final period (full point);
 * sentence fragments – the list is typically introduced by an introductory fragment ending with a colon;
 * titles of works – they retain the original capitalization of the titles;
 * other elements – they are formatted consistently in either sentence case or lower case.

Wikilinks
Make links only where they are relevant and helpful in the context: Excessive use of hyperlinks can be distracting and may slow the reader down. Redundant links (like the one in the tallest people on Earth) clutter the page and make future maintenance harder. High-value links that worth pursuing should stand out clearly.

Linking to sections: A hash sign followed by the appropriate heading will lead to a relevant part of a page. For example,  links to a particular section of the article Apostrophe.

Initial capitalization: Wikipedia's MediaWiki software does not require that wikilinks begin with an upper-case character. Capitalize the first letter only where this is naturally called for, or when specifically referring to the linked article by its name (see also related rule for italics in cross-references): Snakes are often venomous, but lizards only rarely.

Check links: Ensure the destination is the intended one; many dictionary words lead to disambiguation pages and not to complete or well-chosen articles.

Keep markup simple
Other things being equal, keep markup simple. This makes wikitext easier to understand and edit, and the results seen by the reader more predictable. Use HTML and CSS markup sparingly. See: KISS principle.

In general, wikitext formatting is considered easier to use than HTML and wikitext is preferred if there are equivalents; see Help:HTML in wikitext. Obsolete elements and attributes should be updated or removed. There are many templates that allow HTML markup to be used without putting it in articles directly, such as em (see MOS:EMPHASIS) and strong (see MOS:BOLD).

An HTML character entity is sometimes better than the equivalent Unicode character, which may be difficult to identify in edit mode; for example,  is explicit whereas   (the upper-case form of Greek  ) may be misidentified as the Latin.

Formatting issues
Modifications in font size, blank space, and color are an issue for the Wikipedia site-wide style sheet and should be reserved for special cases only.

Typically, the use of custom font styles:
 * reduces consistency, as the text no longer looks uniform;
 * reduces usability, as it may be impossible for people with custom style sheets (e.g. for accessibility reasons) to override it, and may clash with a different skin or inconvenience people with color blindness ; and
 * causes disputes, as other editors may disagree aesthetically with the choice of style.

Specify font sizes (for example with  ) rather than  (like  ). The resulting font size of any text should not drop below 85% of the page's default font size.

Color coding
Do not use color to mark differences in text: they may be invisible to people with color blindness and useless in black-and-white printouts or displays.

Choose colors such as maroon  and  teal  that are distinguishable by readers with the most common form of colorblindness, and  mark the differences with change of font or some other means (<span style="background: white; font-family: Georgia, serif; color: maroon; font face: Times New Roman">maroon and alternative font face,  teal ). Avoid low contrast between text and background colors. See also color coding.

Even for readers with unimpaired color vision, excessive background shading of table entries impedes readability and recognition of Wikilinks. Background color should be used only as a visual cue and should be subtle (consider using lighter, less-dominant pastel hues) rather than glaring.

Indentation
Do not use quotation templates to indent non-quotations. Various templates are available for indentation, including to indent an entire block and  to indent inline.

Do not use  (description list markup) to indent text in articles, even though it is common on talk pages. It causes accessibility problems and outputs invalid HTML.

Controlling line breaks
It is sometimes desirable to force a text segment to appear entirely on a single line—‌that is, to prevent a line break (line wrap) from occurring anywhere within it.
 * A non-breaking space (or hard space) will never be used as a line-break point. Markup: for 19kg, code.
 * Or use, , or (all equivalent). Markup: for 5° 24′ N, code.

It is desirable to prevent line breaks where breaking across lines might be confusing or awkward. For example:

Whether a non-breaking space is appropriate depends on context: whereas it is appropriate to use  in prose, it may be counterproductive in a table (where an unattractive break may be acceptable to conserve precious horizontal space) and unnecessary in a short parameter value in an infobox (where a break would never occur anyway).

A line break may occur at a thin space (, or ), which is sometimes used to correct too-close placement of adjacent characters. To prevent this, consider using.

Insert non-breaking and thin spaces as named character reference ( or  ), or as templates that generate these, and never by entering them directly into the edit window from the keyboard – they are visually indistinguishable from regular spaces, and later editors will be unable to see what they are. Inside wikilinks, a construction such as works but  doesn't.

Scrolling lists and collapsible content
Elements that can selectively display or hide content can interfere with the ability of readers to access said content. These mechanisms include scrolling lists, and templates like that can be toggled between collapsed and uncollapsed states using a [hide / show] button. These mechanisms should not be used to conceal "spoiler" information. Templates should generally not be used to store article text at all, as it interferes with editors' ability to find and edit it. Moreover, content in an article should never be collapsed by default. This applies equally to content in footnotes, tables, and embedded lists, image galleries, and image captions.

If such mechanisms are used, care must be taken to ensure the content remains accessible for all users, including those with limited CSS or JavaScript support. What's more, careless use of collapsible templates will impact accessibility for the clear majority of readers (more than 60%) who use the mobile version of the site, which does not support collapsing and will either completely uncollapse or completely hide the content within the template. The usability of the mobile site is easy to test with the "Mobile view" link at the bottom of each page.

When hiding content is desired, it must be done using the  parameter of relevant templates, or manually-added CSS classes , and   (see Help:Collapsing). Other methods of hiding content should not be used, as they may render content inaccessible to many users, such as those browsing Wikipedia with JavaScript disabled, browsing the mobile version, or using proxy services such as Google Web Light.

Collapsed or auto-collapsing cells or sections may be used with tables if they simply repeat information covered in the main text (or are purely supplementary, e.g., several past years of statistics in collapsed tables for comparison with a table of uncollapsed current stats). Auto-collapsing is often a feature of navboxes. A few infoboxes also use pre-collapsed sections for infrequently accessed details. If information in a list, infobox, or other non-navigational content seems extraneous or trivial enough to inspire pre-collapsing it, consider raising a discussion on the article (or template) talk page about whether it should be included at all. If the information is important and the concern is article density or length, consider dividing the article into more sections, integrating unnecessarily list-formatted information into the article prose, or splitting the article.

Invisible comments
Editors use "invisible" comments – not shown in the rendered page seen by readers of the article, but visible in the source editing mode when an editor opens the article for editing – to communicate with one another.

Invisible comments are useful for alerting other editors to issues such as common mistakes that regularly occur in the article, a section title's being the target of an incoming link, or pointing to a discussion that established a consensus relating to the article. They should not be used to instruct other editors not to perform certain edits, although where existing local consensus is against making such an edit, they may usefully draw the editor's attention to that. Avoid adding too many invisible comments because they can clutter the wiki source for other editors. Check that your invisible comment does not change the formatting, for example by introducing unwanted white space in the rendered page.

To leave an invisible comment, enclose the text you intend to be read only by editors between  and. For example: This notation can be inserted with a single click in wiki markup, just under the edit pane in edit mode.
 * <!-- >If you change this section title, also change the links to it on the pages ...</!--> (there are bots which can do this, see MOS:RENAMESECTION)
 * <!-- >When adding table entries, remember to update the total given in the text.</!-->

Pronunciation
Pronunciation in Wikipedia is indicated in the International Phonetic Alphabet (IPA). In most situations, for ease of understanding by the majority of readers and across variants of the language, quite broad IPA transcriptions are best for English pronunciations. See Help:IPA/English and Help:IPA (general) for keys, and for templates that link to these keys. For English pronunciations, pronunciation respellings may be used the IPA.
