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.).
Ossetian language
Ossetian is the spoken and literary language of the Ossetes, a people living in the central part of the Caucasus and constituting the basic population of the republic of North Ossetia–Alania, which belongs to the Russian Federation, and of South Ossetia, which is "de facto" independent (but is "de jure" part of the Georgian Republic according to most other states). Ossetian belongs to the Iranian group of the Indo-European family of languages (as hinted by its endonym, ирон). Within Iranian it is placed in an Eastern subgroup and further to a Northeastern sub-subgroup, but these are areal rather than genetic groups. The other Eastern Iranian languages such as Pashto and Yaghnobi show certain commonalities but also deep-reaching divergences from Ossetic.
