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.).
Kaqchikel language
The Kaqchikel language (in modern orthography; formerly also spelled Cakchiquel or Cachiquel) is an indigenous Mesoamerican language and a member of the Quichean–Mamean branch of the Mayan languages family. It is spoken by the indigenous Kaqchikel people in central Guatemala. It is closely related to the K'iche' (Quiché) and Tz'utujil languages.
