Google Translate supports translation between over 100 languages. This includes widely spoken languages such as English, Spanish, French, German, Chinese, Japanese, Arabic, Russian, and many others. It also includes less commonly spoken languages and regional dialects. The number of supported languages may have increased since then as Google continues to expand and update its language offerings. To get the most accurate and up-to-date information on the specific languages supported by Google Translate, I recommend visiting the Google Translate website or checking the Google Translate app for the latest language options.
