Chechens
The main language of the Chechen people is Chechen. Chechen belongs to the family of Nakh languages (Northeast Caucasian languages). Literary Chechen is based on the central lowland dialect. Other related languages include Ingush, which has speakers in the neighbouring Ingushetia, and Batsbi, which is the language of the people in the adjoining part of Georgia. At various times in their history, Chechens used Georgian, Arabic and Latin alphabets; as of 2008, the official one is now the Cyrillic script of Russia.
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.
