Google Translate Switch Languages

If it’s necessary, you can easily swap the translation direction using the "Switch language" button.

If the source language is set to "Detect language", the switch language option isn't available.

If the language detector identifies that the target language of the translation direction is identical to the language of the original text, the language switch performs automatically when you press the Translate button.

When you press the Translate button, the language detection tool analyzes the language of the source text, performs the language detection, swaps the translation direction, and completes the translation.
