Tat Language is a group of dialects spoken primarily in the Tat community, which is found mainly in Azerbaijan and parts of Iran. It belongs to the Northwest Iranian branch of the Indo-Iranian languages and has influences from Persian and Azerbaijani. The language is considered endangered, with a declining number of speakers due to urbanization and cultural assimilation. Efforts are being made to preserve Tat Language through documentation and education, as it holds significant cultural and historical value for the Tat people.
