Original sentence: Both are members of the Kypchak (or Northwestern) group of Turkic languages, although they are also partly derived from the ancient Volga Bolgar language.Only about 4,500,000 of them are Tatars.Other speakers are Bashkirs (520,000), Russians (130,000), Chuvashs (70,000), Maris (42,000), Udmurts and Mordvins.Tatar was used as literary writing language before 1930, but since then only Russian has been used as a written language.The Siberian Tatars use a different dialect from literary Tatar.The Tatar language strongly influenced most of the Caucasian, Slavic and Finno-Ugric languages in the Volga River area.The language of the Chulym Tatars is considered to be an independent language, as are the other "Tatar" languages to the East of them.The literary Tatar language is based on Kazan Tatar's Middle (Tatarstan) dialect and the Old Tatar language (İske Tatar Tele).There are local Tatar language speakers in Tatarstan, this number includes Azeri, Armenian, Kazakh and Jewish communities
