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.
Khwarshi language
Khwarshi (also spelled "Xvarshi, Khvarshi") is a Northeast Caucasian language spoken in the Tsumadinsky-, Kizilyurtovsky- and Khasavyurtovsky districts of Dagestan by the Khwarshi people. The exact number of speakers is not known, but the linguist Zaira Khalilova, who has carried out fieldwork in the period from 2005 to 2009, gives the figure 8,500. Other sources give much lower figures, such as Ethnologue with the figure 1,870 and the latest population census of Russia with the figure 1,872. The low figures are because many Khwarshi have registered themselves as being Avar speakers, which is also considered their literary language.
