Translating

As part of a module, we can define a set of translations. A full description of how to create language files is available in Chapter 9. When we create module translation files, we must name the file according to a specific naming convention: the language tag, a period, the Joomla! parsed module name. For example, the British English translation file for the module My Extension would be called en-GB.mod_myextension.php.

Module translation files are located in the language and administrator/language folders. If you are creating a frontend module, use the language folder. If you are creating a backend module, use the administrator/language folder.
