Tuvan language
Tuvan (Tuvan: тыва дыл, tyva dyl), also known as Tuvinian, Tyvan or Tuvin, is a Turkic language spoken in the Republic of Tuva in south-central Siberia in Russia. The language has borrowed a great number of roots from the Mongolian language, Tibetan and more recently from the Russian language. There are small diaspora groups of Tuvan people that speak distinct dialects of Tuvan in the People's Republic of China and in Mongolia.
History
The earliest record of Tuvan is from the early 19th century by Wu-li-ya-su-tai-zhi lue (烏里蘇台志略), Klaproth 1823, Castrén 1857, Katanov and Radlov etc .
