High Quality Content by WIKIPEDIA articles! The Northeast Caucasian languages, also called Nakh(o)-Dag(h)estanian, constitute a language family spoken in the Russian republics of Dagestan, Chechnya, Ingushetia, northern Azerbaijan, and in northeastern Georgia, as well as in diaspora populations in Russia, Turkey, and the Mideast. Several names have been in use for this family. The most common term, Northeast Caucasian, contrasts the three established families of the Caucasus language area: Northeast Caucasian, Northwest Caucasian, and South Caucasian (Kartvelian). This may be shortened to East Caucasian, especially by those linguists who accept the North Caucasian languages as a language family. The older term Nakho-Dagestanian reflected an erstwhile primary division of the family into Nakh and Dagestanian branches, a view which is no longer widely accepted. The rare term Caspian (that is, bordering the Caspian Sea) is only used in opposition to Pontic (that is, bordering the Black Sea) for the Northwest Caucasian languages.
