Chechens
In 1989, 73.4% spoke Russian, though this figure has declined due to the wars for a large number of reasons (including the lack of proper education, the refusal to learn the language, and the mass dispersal of the Chechen diaspora due to the war). Chechens in the diaspora often speak the language of the country they live in (English, German, Arabic, Polish, Georgian, etc.).
Chechnya
According to Leonti Mroveli, the 11th-century Georgian chronicler, the word Caucasian is derived from the Vainakh ancestor Kavkas.
According to Professor George Anchabadze of Ilia State University American linguist Dr. Johanna Nichols "has used language to connect the modern people of the Caucasus region to the ancient farmers of the Fertile Crescent" and her research suggests that "farmers of the region were proto-Nakh-Daghestanians." Nichols stated: "The Nakh–Dagestanian languages are the closest thing we have to a direct continuation of the cultural and linguistic community that gave rise to Western civilization." Dr. Henry Harpending, University of Utah, supports her claims.
