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.
Chechen language
Unlike most other languages of the Caucasus, Chechen has an extensive inventory of vowel sounds, about 44, putting its range higher than most languages of Europe (most vowels being the product of environmentally-conditioned allophonic variation, which varies by both dialect and method of analysis). Many of the vowels are due to umlaut, which is highly productive in the standard dialect. None of the spelling systems used so far have distinguished the vowels with complete accuracy.
