This module is used to retrieve and manage the languages that can have Wiktionary entries, and the information associated with them. See Wiktionary:Languages for more information.

For the languages and language varieties that may be used in etymologies, see Module:etymology languages. For language families, which sometimes also appear in etymologies, see Module:families.

This module provides access to other modules. To access the information from within a template, see Module:languages/templates.

The information itself is stored in the various data modules that are subpages of this module. These modules should not be used directly by any other module, the data should only be accessed through the functions provided by this module.
