Concept
The Northeast Caucasian languages, also called East Caucasian, Nakh-Daghestani or Vainakh-Daghestani, or sometimes Caspian languages (from the Caspian Sea, in contrast to Pontic languages for the Northwest Caucasian languages), is a family of languages spoken in the Russian republics of Dagestan, Chechnya and Ingushetia and in Northern Azerbaijan as well as in diaspora populations in Western Europe and the Middle East. They are occasionally called Caspian, as opposed to Pontic for the Northwest Caucasian languages. Several names have been in use for this family. The most common term, Northeast Caucasian, contrasts the three established families of the Caucasian languages: Northeast Caucasian, Northwest Caucasian (Abkhaz–Adyghean) and South Caucasian (Kartvelian). This may be shortened to East Caucasian. The term Nakh(o)-Dagestanian can be taken to reflect a primary division of the family into Nakh and Dagestanian branches, a view which is no longer widely accepted, or Dagestanian can subsume the entire family. The rare term North Caspian (as in bordering the Caspian Sea) is only used in opposition to the use of North Pontic (as in bordering the Black Sea) for the Northwest Caucasian languages. Historically, Northeast Caucasian phonemic inventories were thought to be smaller than those of the neighboring Northwest Caucasian family. However, more recent research has revealed that many Northeast Caucasian languages are much more phoneme-rich than previously believed, with some languages containing as many as 70 consonants. In addition to numerous front obstruents, many Northeast Caucasian languages also possess a number of back consonants, including uvulars, pharyngeals, and glottal stops and fricatives. Northeast Caucasian phonology is also notable for its use of numerous secondary articulations as contrastive features. Whereas English consonant classes are divided into voiced and voiceless phonemes, Northeast Caucasian languages are known to contrast voiced, voiceless, ejective and tense phones, which contributes to their large phonemic inventories.
