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.).
Kazakh language
Kazakh or Kazak (Cyrillic: or ; Arabic: or ; , ) belongs to the Kipchak branch of the Turkic languages. It is closely related to Nogai, Kyrgyz, and Karakalpak. Kazakh is the official language of the Republic of Kazakhstan and a significant minority language in the Ili Kazakh Autonomous Prefecture in Xinjiang, China and in the Bayan-Ölgii Province of Mongolia. Kazakh is also spoken by many ethnic Kazakhs through the former Soviet Union (approximately 472,000 in Russia according to the 2010 Russian Census), Afghanistan, Iran, Turkey, and Germany.
