Category:Language data modules

These modules contain definitions and metadata for all language and language family codes on Wiktionary. See Languages for more information.

The language codes are organised as follows:
 * contains two-letter (ISO 639-1) language codes.
 * contains three-letter (mostly ISO 639-3) language codes. They are organised into further submodules by the first letter of each code; the main  module itself is empty.
 * contains exceptional language codes that were created by Wiktionary. These consist of a series of at least two (usually 3-letter) codes separated by hyphens.
