Wikipedia:WikiProject Languages/Template

Classification
A description of the genetic classification of the language.

History
Probable history of the language. What language(s) it is derived from and when it started diverging from the ancestral language(s). Dates of movement of major groups of speakers, etc. Brief descriptions of important changes in the language, such as reduction of sounds or grammatical cases.

When creating sub-articles, use the formula History of XXX where XXX is the standard English name of the language. Avoid the bulkier format History of XXX language since there is no need for disambiguation in this case.

Geographic distribution
In what countries/regions the language is spoken, and how many people speak it there.

Official status
List which countries have this language as an official language or other special status.

Dialects/Varieties
List of varieties/dialects of the language. Major dialects with lots of information should probably have their own page.

Derived languages
Creoles and other languages that are derived from this language.

Sounds/Phonology
If there is a significant amount of information here, it is probably best to have a separate article on the phonology, called XXX phonology (eg Somali phonology). See WikiProject Phonetics/Phonology template for a suggested structure.

If a separate page is not warranted, it may still be best to divide the information in this section into sub-sections following the structure on the above phonology template.

If there is a separate page, give a brief summary here, eg the number of consonant and vowel phonemes; important features such as phonemic use of tone or vowel harmony; and unusual or interesting features of the language's phonology.

Grammar
A general outline of the grammar of the language. Focus on what makes the grammar of the language unique compared to other languages, related as well as unrelated. Lists of each word class and their individual properties, as well as full-fledged inflection or conjugation tables, are probably best put in a separate article.

Morphology
General description of the morphology of the language.

Syntax
General description of the syntax of the language. What is the usual word order (SVO, SOV, VSO, etc.)? Theoretical descriptions, lists of example sentences, and explanations involving syntax trees are probably best put in a separate article.

Vocabulary/Lexis
This section should contain a discussion of any special features of the vocabulary of the language, like if it contains a large number of borrowed words or a different sets of words for different politeness levels, taboo groups, etc.

Writing system
A brief description of the writing system(s) used to write the language. Writing systems have their own page, so what's written here should just be a brief discussion of how this language makes any special use of the writing system and a link to all the writing systems used to write the language.

Examples
Some short examples of the language in the writing system(s) used to write the language. You might also include sound samples of the language being spoken. Avoid making lists of tourist phrases such as "hello", "goodbye" and "where's the lavatory?" since these do not represent the specifics of either grammar or phonetics particularly well.

Categories
If there are reliable sources about when the language was first attested, consider adding the page to the relevant Category:Languages by time subcategory. If the language is extinct and there are reliable sources about when the language went extinct, consider adding the page to the relevant Category:Extinct languages by time.
