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.).
Vainakhish language
The Vainakhish language consist of the dialect continuum between the Chechen and Ingush languages, mainly spoken in the Russian republics of Chechnya and Ingushetia, as well as in the Chechen diaspora. Together with Bats it forms the Nakh branch of the Northeast Caucasian languages family.
