In the Tolgee platform, you can manage the languages of your projects. There is a single base language for the project, and multiple target languages.

The BCP 47 language tag

Tolgee uses a standard BCP 47 language tag to identify languages. When setting up language, we enable you to use custom language tags. However, we strongly recommend you use BCP-47 language tags, as Tolgee recognizes such languages for machine translation and other features.

You can read more about the BCP 47 language tag in the official RFC: Matching of Language Tags
