LibreTranslate

Supported languages

ISO-639-1 codes the !translate command accepts as a target language argument.

!translate <code> <text> accepts the following ISO-639-1 codes. This is a permissive list — LibreTranslate will reject codes its specific model doesn't ship with, and the API surfaces that error to the user.

Default target

If no target code is given, English (en) is used:

!translate привет        → "Hello"            (auto-detect → en)
!translate ru hello roof → "привет крыша"     (en → ru)
!translate :de tank rush → "Panzer-Sturm"     (forced parse → de)

The :<code> prefix is the forced-code form — useful when the message you want to translate starts with what looks like a language code (e.g. !translate :en english is hard).
