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.
Tushetians
The Tushetians , or Tush , are a subgroup of Georgians who mainly live in Tusheti.
The Tush divide themselves into two groups, the Chagma-Tush, who speak the local Georgian dialect and Tsova-Tush, also known as Bats or Batsbi, who speak the Bats language, a Nakh language (cousin of Chechen and Ingush). Most Bats also speak Georgian, to which there is a continuing trend of linguistic assimilation. Despite differences in language and culture (to a degree), both Chagma- and Tsova-Tush consider themselves to be part of the larger group of Tush, which in turn is considered a subgroup of Georgians.
