Chechens
In 1989, 73.4% spoke Russian, though this figure has declined due to the wars for a large number of reasons (including the lack of proper education, the refusal to learn the language, and the mass dispersal of the Chechen diaspora due to the war). Chechens in the diaspora often speak the language of the country they live in (English, German, Arabic, Polish, Georgian, etc.).
Chechen language
Chechen is an agglutinative language with an ergative–absolutive morphosyntactic alignment. Chechen nouns belong to one of several genders or classes (6), each with a specific prefix with which the verb or an accompanying adjective agrees. The verb does not agree with the subject or object's person or number, having only tense forms and participles. Among these are an optative and an antipassive. Some verbs, however, do not take these prefixes.
