 | This hidden category deliberately ignores the MOS:CIRCA guideline to use "c." in articles, the MOS:DASH guideline for year ranges, or both. The category should not be moved. |
Template documentationThis category message box can be placed at the top of category pages for which the official ISO 639 name contains either "ca." as an abbreviation for "circa", a hyphen in a year range, or both. Each of these typographical conventions would normally be changed to conform to MOS:CIRCA and MOS:DASH, respectively, but since these language categories use the official ISO names for the languages, the category names are an exception to the English Wikipedia's guidelines.
See this ISO 639 language page for an example of a language name that causes this category name exception.
