Templat:Citation Style documentation/language

• language: The language in which the source is written, if not English. Displays in parentheses with "in" before the language name or names. Use the full language name or ISO 639-1 code. When the source uses more than one language, list them individually, separated by commas, e.g. |language=French, German. The use of language names or language codes recognized by Wikimedia adds the page to the appropriate subcategory of CS1 foreign language sources; do not use templates or wikilinks.
