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.
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.
