Appendix D. Language Tags

Language tags are a system defined in RFC 3066, which is used in various Internet protocols and formats, including HTML, HTTP, and XML. For example, an HTTP request often has an Accept-Language header, an HTTP response can have a Content-Language header, and any HTML element can have a lang="en-US" or (in XML and XHTML) an xml:lang="en-US" attribute to indicate that its content is in that language.

There are many more language tags than are presented here; for the full list, see documentation for the Perl module I18N::LangTags::List. This appendix lists major languages, in alphabetical order by their English names.
