northwestern (Kipchak) language of the Turkic subfamily of Altaic languages. It is spoken in the republic of Tatarstan in west-central Russia and in Romania, Bulgaria, Turkey, and China. There are numerous dialectal forms.

Crimean Tatar belongs to the same division of the Turkic languages. It has its roots in the language of the Golden Horde in the 13th century and was the official literary language in the Crimea until the 17th century, when it was replaced by Ottoman Turkish. Revived as a literary language in the 19th century, it declined in use in the 20th century after Stalin's deportation of the Crimean Tatars. See also Turkic languages.
