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.
Kerek language
In 1997 there were still two speakers remaining, but by 2005 the language was considered extinct. According to the 2010 census, there were 10 people claiming Kerek as their native language, a number which may include partial speakers and non-speakers who claim the language as part of their ethnic heritage. Over the 20th century many members of the Kerek ethnic group shifted to Chukchi, the language of the majority ethnic group in the area, but now most Chukchis and Kereks speak Russian.
