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.
Teip
Historically, if non-Chechen minorities living in Chechen lands wanted to take part in the political processes of the Chechen nation, and integrate into it, they would request admittance as an ethnic teip. They would continue, for a time, to speak their other languages, but also learned Chechen. Due to the encouragement of teip exogamy, as the generations passed, they would come to be heavily intermarried into the Chechen nation and as a result, be slowly Chechenized culturally and linguistically. The level of Chechenization varies between these foreign-origin teips, with some well-preserving their cultural traits and others not. They are nonetheless known as impure teips (not in a derogatory sense), for their foreign origin. Their loyalty to the nation is not any more in question than a Chechen-origin teip.
