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.).
Chepang people
The language is also known as Chepang but is called Chyo-bang by the people themselves. Some Bahun Chettri castes call these people the "Praja" meaning "political subjects". The people speak 3 different dialects of this Tibeto-Burman language that is closely related to Raute and Raji, two undocumented languages spoken in western Nepal.
