Translations:Manual:Language/2/en

In MediaWiki, there are various kinds of languages:
 * The site content language ($wgContLang, based on $wgLanguageCode), which should generally stay the same as long as the wiki exists.
 * The site content language variant (Manual:$wgDefaultLanguageVariant) is the default variant when LanguageConverter is implemented for that language.
 * The user interface language ($contextSource->getLanguage formerly $wgLang), which can be changed in your preferences or with  in the URL, but also generally remains the same while using the wiki.
 * The page content language. This can be different for each page, even if the site and user language is the same. It is defined in getPageLanguage in Title, representing what language the wikitext source is written in.
 * The page view language aka user language variant which is a language variant of page content language, as preferred by the user. It can also be set through  (or ) in the URL (e.g. by selecting one of the tabs) if it is a variant of the content language of the page being viewed. It's defined in getPageViewLanguage in Title, representing what language the rendered HTML content is written in.
