Ellipsis

The ellipsis, rendered ..., alternatively described as suspension points/dots, or points/periods of ellipsis, or colloquially, dot-dot-dot, are punctuation marks consisting of a series of three dots. An ellipsis can be used in many ways, including for intentional omission of text or to imply a concept without using words.

The plural is ellipses.

The term originates from the ἔλλειψις, élleipsis meaning 'leave out'.

Opinions differ on how to render an ellipsis in printed material and are to some extent based on the technology used for rendering. Many style guides are still influenced by the typewriter. According to The Chicago Manual of Style, it should consist of three periods, each separated from its neighbor by a non-breaking space:. ... According to the AP Stylebook, the periods should be rendered with no space between them: .... A third option available in electronic text  is to use the precomposed character U+2026 ….

Style
The most common forms of an ellipsis include a row of three periods (i.e., dots or full points), as characters ... or as a precomposed triple-dot glyph, the horizontal ellipsis ….

Style guides often include rules governing ellipsis use. For example, The Chicago Manual of Style (Chicago style) recommends that an ellipsis be formed by typing three periods, each with a non-breaking space on both sides. .., while the Associated Press Stylebook (AP style) puts the dots together, but retains a space before and after the group, thus: ....

When a sentence ends with ellipsis, some style guides indicate there should be four dots; three for ellipsis and a period. Chicago advises it, as does the Publication Manual of the American Psychological Association (APA style), while some other style guides do not; the Merriam-Webster Dictionary and related works treat this style as optional, saying that it "may" be used.

When text is omitted following a sentence, a period (full stop) terminates the sentence, and a subsequent ellipsis indicates one or more omitted sentences before continuing a longer quotation. Business Insider magazine suggests this style and it is also used in many academic journals. The Associated Press Stylebook favors this approach.

In writing
In her book on the ellipsis, Ellipsis in English Literature: Signs of Omission, Anne Toner suggests that the first use of the punctuation in the English language dates to a 1588 translation of Terence's Andria, by Maurice Kyffin. In this case, however, the ellipsis consists not of dots but of short dashes. "Subpuncting" of medieval manuscripts also denotes omitted meaning and may be related.

Occasionally, it would be used in pulp fiction and other works of early 20th-century fiction to denote expletives that would otherwise have been censored.

An ellipsis may also imply an unstated alternative indicated by context. For example, "I never drink wine ..." implies that the speaker does drink something else—such as vodka.

In reported speech, the ellipsis can be used to represent an intentional silence.

In poetry, an ellipsis is used as a thought-pause or line break at the caesura or this is used to highlight sarcasm or make the reader think about the last points in the poem.

In news reporting, often put inside square brackets, it is used to indicate that a quotation has been condensed for space, brevity or relevance, as in "The President said that [...] he would not be satisfied", where the exact quotation was "The President said that, for as long as this situation continued, he would not be satisfied".

Herb Caen, Pulitzer-prize-winning columnist for the San Francisco Chronicle, became famous for his "three-dot journalism".

Depending on context, ellipsis can indicate an unfinished thought, a leading statement, a slight pause, an echoing voice, or a nervous or awkward silence. Aposiopesis is the use of an ellipsis to trail off into silence—for example: "But I thought he was..." When placed at the end of a sentence, an ellipsis may be used to suggest melancholy or longing.

American English
The Chicago Manual of Style suggests the use of an ellipsis for any omitted word, phrase, line, or paragraph from within but not at the end of a quoted passage. There are two commonly used methods of using ellipses: one uses three dots for any omission, while the second one makes a distinction between omissions within a sentence (using three dots: . . .) and omissions between sentences (using a period and a space followed by three dots: . ...). The Chicago Style Q&A recommends that writers avoid using the precomposed … (U+2026) character in manuscripts and to place three periods plus two nonbreaking spaces (. . .) instead, leaving the editor, publisher, or typographer to replace them later.

The Modern Language Association (MLA) used to indicate that an ellipsis must include spaces before and after each dot in all uses. If an ellipsis is meant to represent an omission, square brackets must surround the ellipsis to make it clear that there was no pause in the original quote: [. . . ]. Currently, the MLA has removed the requirement of brackets in its style handbooks. However, some maintain that the use of brackets is still correct because it clears confusion.

The MLA now indicates that a three-dot, spaced ellipsis. .. should be used for removing material from within one sentence within a quote. When crossing sentences (when the omitted text contains a period, so that omitting the end of a sentence counts), a four-dot, spaced (except for before the first dot) ellipsis. . .. should be used. When ellipsis points are used in the original text, ellipsis points that are not in the original text should be distinguished by enclosing them in square brackets (e.g. text [...] text).

According to the Associated Press, the ellipsis should be used to condense quotations. It is less commonly used to indicate a pause in speech or an unfinished thought or to separate items in material such as show business gossip. The stylebook indicates that if the shortened sentence before the mark can stand as a sentence, it should do so, with an ellipsis placed after the period or other ending punctuation. When material is omitted at the end of a paragraph and also immediately following it, an ellipsis goes both at the end of that paragraph and at the beginning of the next, according to this style.

According to Robert Bringhurst's Elements of Typographic Style, the details of typesetting ellipses depend on the character and size of the font being set and the typographer's preference. Bringhurst writes that a full space between each dot is "another Victorian eccentricity. In most contexts, the Chicago ellipsis is much too wide"—he recommends using flush dots (with a normal word space before and after), or thin-spaced dots (up to one-fifth of an em), or the prefabricated ellipsis character. Bringhurst suggests that normally an ellipsis should be spaced fore-and-aft to separate it from the text, but when it combines with other punctuation, the leading space disappears and the other punctuation follows. This is the usual practice in typesetting. He provides the following examples:

In legal writing in the United States, Rule 5.3 in the Bluebook citation guide governs the use of ellipses and requires a space before the first dot and between the two subsequent dots. If an ellipsis ends the sentence, then there are three dots, each separated by a space, followed by the final punctuation (e.g. Hah . . . ?). In some legal writing, an ellipsis is written as three asterisks, *** or * * *, to make it obvious that text has been omitted or to signal that the omitted text extends beyond the end of the paragraph.

British English
The Oxford Style Guide recommends setting the ellipsis as a single character … or as a series of three (narrow) spaced dots surrounded by spaces, thus: .... If there is an ellipsis at the end of an incomplete sentence, the final full stop is omitted. However, it is retained if the following ellipsis represents an omission between two complete sentences.

The … fox jumps … The quick brown fox jumps over the lazy dog. … And if they have not died, they are still alive today. It is not cold … it is freezing cold.

Contrary to The Oxford Style Guide, the University of Oxford Style Guide demands an ellipsis not to be surrounded by spaces, except when it stands for a pause; then, a space has to be set after the ellipsis (but not before). An ellipsis is never preceded or followed by a full stop.

The...fox jumps... The quick brown fox jumps over the lazy dog...And if they have not died, they are still alive today. It is not cold... it is freezing cold.

In Polish
When applied in Polish syntax, the ellipsis is called wielokropek, literally 'multidot'. The word wielokropek distinguishes the ellipsis of Polish syntax from that of mathematical notation, in which it is known as an elipsa. When an ellipsis replaces a fragment omitted from a quotation, the ellipsis is enclosed in parentheses or square brackets. An unbracketed ellipsis indicates an interruption or pause in speech. The syntactic rules for ellipses are standardized by the 1983 Polska Norma document PN-83/P-55366, Zasady składania tekstów w języku polskim (Rules for Setting Texts in Polish).

In Russian
The combination "ellipsis+period" is replaced by the ellipsis. The combinations "ellipsis+exclamation mark" and "ellipsis+question mark" are written in this way: !.. ?..

In Japanese
The most common character corresponding to an ellipsis is called 3-ten rīdā ("3-dot leaders", …). 2-ten rīdā exists as a character, but it is used less commonly. In writing, the ellipsis consists usually of six dots (two 3-ten rīdā characters, ……). Three dots (one 3-ten rīdā character) may be used where space is limited, such as in a header. However, variations in the number of dots exist. In horizontally written text the dots are commonly vertically centered within the text height (between the baseline and the ascent line), as in the standard Japanese Windows fonts; in vertically written text the dots are always centered horizontally. As the Japanese word for dot is pronounced "ten", the dots are colloquially called "ten-ten-ten" (てんてんてん, akin to the English "dot dot dot").

In text in Japanese media, such as in manga or video games, ellipses are much more frequent than in English, and are often changed to another punctuation sign in translation. The ellipsis by itself represents speechlessness, or a "pregnant pause". Depending on the context, this could be anything from an admission of guilt to an expression of being dumbfounded at another person's words or actions. As a device, the ten-ten-ten is intended to focus the reader on a character while allowing the character to not speak any dialogue. This conveys to the reader a focus of the narrative "camera" on the silent subject, implying an expectation of some motion or action. It is not unheard of to see inanimate objects "speaking" the ellipsis.

In Chinese
In Chinese, the ellipsis is six dots (in two groups of three dots, occupying the same horizontal or vertical space as two characters). In horizontally written text the dots are commonly vertically centered along the midline (halfway between the Roman descent and Roman ascent, or equivalently halfway between the Roman baseline and the capital height, i.e. ⋯⋯). This is generally true of Traditional Chinese, while Simplified Chinese tends to have the ellipses aligned with the baseline ; in vertically written text the dots are always centered horizontally (i.e. ). Also note that Taiwan and Mainland China have different punctuation standards.

In Spanish
In Spanish, the ellipsis is commonly used as a substitute of et cetera at the end of unfinished lists. So it means "and so forth" or "and other things".

Other use is the suspension of a part of a text, or a paragraph, or a phrase or a part of a word because it is obvious, or unnecessary, or implied. For instance, sometimes the ellipsis is used to avoid the complete use of expletives.

When the ellipsis is placed alone into a parenthesis (...) or—less often—between brackets [...], which is what happens usually within a text transcription, it means the original text had more contents on the same position but are not useful to our target in the transcription. When the suppressed text is at the beginning or at the end of a text, the ellipsis does not need to be placed in a parenthesis.

The number of dots is three and only three.

In French
In French, the ellipsis is commonly used at the end of lists to represent et cetera. In French typography, the ellipsis is written immediately after the preceding word, but has a space after it, for example: comme ça... pas comme ceci. If, exceptionally, it begins a sentence, there is a space before and after, for example: Lui&thinsp;? ... vaut rien, je crois.... However, any omitted word, phrase or line at the end of a quoted passage would be indicated as follows: [...] (space before and after the square brackets but not inside), for example: ... à Paris, Nice, Nantes, Toulouse [...].

In German
In German, the ellipsis in general is surrounded by spaces, if it stands for one or more omitted words. On the other side there is no space between a letter or (part of) a word and an ellipsis, if it stands for one or more omitted letters, that should stick to the written letter or letters.

Example for both cases, using German style: ''The first el...is stands for omitted letters, the second ... for an omitted word.''

If the ellipsis is at the end of a sentence, the final full stop is omitted.

Example: I think that ...

In Italian
The Accademia della Crusca suggests the use of an ellipsis ("puntini di sospensione") to indicate a pause longer than a period and, when placed between brackets, the omission of letters, words or phrases. "'Tra le cose più preziose possedute da Andrea Sperelli era una coperta di seta fina, d’un colore azzurro disfatto, intorno a cui giravano i dodici segni dello Zodiaco in ricamo, con le denominazioni […] a caratteri gotici.' (Gabriele D’Annunzio, Il piacere)"

In mathematical notation
An ellipsis is used in mathematics to mean "and so forth"; usually indicating the omission of terms that follow an obvious pattern as indicated by included terms.

The whole numbers from 1 to 100 can be shown as:


 * $$1,2,3,\ldots,100$$

The positive whole numbers, an infinite list, can be shown as:


 * $$1,2,3,\ldots$$

To indicate omitted terms in a repeated operation, an ellipsis is sometimes raised from the baseline, as:


 * $$1+2+3+\cdots+100$$

But, this raised formatting is not standard. For example, Russian mathematical texts, use the normal, baseline format.

The ellipsis is not a formally defined mathematical symbol. Repeated summations or products may be more formally denoted using capital sigma and capital pi notation, respectively:


 * $$1+2+3+\cdots+100\ = \sum_{n=1}^{100} n = 100?$$ (see termial)
 * $$1 \times 2 \times 3 \times \cdots \times 100\ = \prod_{n=1}^{100} n = 100!$$ (see factorial)

Ellipsis is sometimes used where the pattern is not clear. For example, indicating the indefinite continuation of an irrational number such as:


 * $$\pi=3.14159265\ldots$$

It can be useful to display a formula compactly, for example:


 * $$1+4+9+\cdots+n^2+\cdots+400$$

In set notation, the ellipsis is used as horizontal, vertical and diagonal for indicating missing matrix terms, such as the size-n identity matrix:


 * $$I_n = \begin{bmatrix}1 & 0 & \cdots & 0 \\0 & 1 & \cdots & 0 \\\vdots & \vdots & \ddots & \vdots \\0 & 0 & \cdots & 1 \end{bmatrix}$$

In computer programming
Some programming languages use ellipsis to indicate a range or for a variable argument list.

The CSS  property can be set to , which cuts off text with an ellipsis when it overflows the content area.

More
An ellipsis is sometimes used as the label for a button to access user interface that has been omitted probably due to space limitations  particularly in mobile apps running on small screen devices. This may be described as a "more button".

Similar functionality may be accessible via a button with a hamburger icon (≡) or a narrow version called the kebab icon which is a vertical ellipsis (⋮).

More info needed
According to some style guides, a menu item or button labeled with a trailing ellipsis requests an operation that cannot be completed without additional information and selecting it will prompt the user for input. Without an ellipsis, selecting the item or button will perform an action without user input.



For example, the menu item "Save" overwrites an existing file whereas "Save as..." prompts the user for save options before saving.

Busy/progress
Ellipsis is commonly used to indicate that a longer-lasting operation is in progress like "Loading...", "Saving...".

Sometimes progress is animated with an ellipse-like construct of repeatedly adding dots to a label.

In texting
In text-based communications, the ellipsis may indicate:
 * Floor holding, signal that more is to come, for instance when people break up longer turns in chat.
 * Politeness, for instance indicating topic change or hesitation.
 * Turn construction unit to signal silence, for example when indicating disagreement, disapproval or confusion.

Although an ellipsis is complete with three periods (...), an ellipsis-like construct with more dots is used to indicate "trailing-off" or "silence". The extent of repetition in itself might serve as an additional contextualization or paralinguistic cue; one paper wrote that they "extend the lexical meaning of the words, add character to the sentences, and allow fine-tuning and personalisation of the message".

While composing a text message, some environments show others in the conversation a typing awareness indicator ellipsis to indicate remote activity.

Computer representations
In computing, several ellipsis characters have been codified.

Unicode
Unicode defines the following ellipsis characters:



Unicode recognizes a series of three period characters as compatibility equivalent (though not canonical) to the horizontal ellipsis character.

HTML
In HTML, the horizontal ellipsis character may be represented by the entity reference  (since HTML 4.0), and the vertical ellipsis character by the entity reference   (since HTML 5.0). Alternatively, in HTML, XML, and SGML, a numeric character reference such as  or   can be used.

TeX
In the TeX typesetting system, the following types of ellipsis are available:

In LaTeX, the reverse orientation of  can be achieved with   provided by the   package:   yields.

With the  package from AMS-LaTeX, more specific ellipses are provided for math mode.

Other
The horizontal ellipsis character also appears in older character maps:


 * in Windows-1250—Windows-1258 and in IBM/MS-DOS Code page 874, at code 85 (hexadecimal)
 * in Mac-Roman, Mac-CentEuro and several other Macintosh encodings, at code C9 (hexadecimal)
 * in Ventura International encoding at code C1 (hexadecimal)

Note that ISO/IEC 8859 encoding series provides no code point for ellipsis.

As with all characters, especially those outside the ASCII range, the author, sender and receiver of an encoded ellipsis must be in agreement upon what bytes are being used to represent the character. Naive text processing software may improperly assume that a particular encoding is being used, resulting in mojibake.

Input
In Windows, the horizontal ellipsis can be inserted with Alt133, using the numeric keypad.

In macOS, it can be inserted with Opt (on an English language keyboard).

In some Linux distributions, it can be inserted with AltGr (this produces an interpunct on other systems), or Compose.

In Android, ellipsis is a long-press key. If Gboard is in alphanumeric layout, change to numeric and special characters layout by pressing ?123 from alphanumeric layout. Once in numeric and special characters layout, long press. key to insert an ellipsis. This is a single symbol without spaces in between the three dots ( … ).

In Chinese and sometimes in Japanese, ellipsis characters are made by entering two consecutive horizontal ellipses, each with Unicode code point U+2026. In vertical texts, the application should rotate the symbol accordingly.
