Chechen language
Chechen ( , ) is a Northeast Caucasian language spoken by more than 1.4 million people, mostly in the Chechen Republic and by members of the Chechen diaspora throughout Russia, Jordan, Central Asia (mainly Kazakhstan and Kyrgyzstan), and Georgia.
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.
