|Linguistic classification:||North Caucasian?|
The Northwest Caucasian languages (Adyghe: Азгъэбзэ-Адыгэбзэхэр; Russian: Абхазо-адыгские языки), also called Abkhazo-Adyghean, or sometimes Pontic as opposed to Caspian for the Northeast Caucasian languages, are a group of languages spoken in the Caucasus region, chiefly in Russia (Adygea, Kabardino-Balkaria, Karachay–Cherkessia), the disputed territory of Abkhazia, and Turkey, with smaller communities scattered throughout the Middle East.
The entire family is characterised by a paucity of phonemic vowels (two or three, depending upon the analysis) coupled with rich consonantal systems that include many forms of secondary articulation. Ubykh (Ubyx), for example, had both the minimal number of vowels (two), and probably the largest inventory of consonants outside Southern Africa.
Linguistic reconstructions suggest that both the richness of the consonantal systems and the poverty of the vocalic systems may be the result of a historical process, whereby vowel features such as labialisation and palatalisation were reassigned to adjacent consonants. For example, ancestral */ki/ may have become /kʲə/ and */ku/ may have become /kʷə/, losing the old vowels */i/ and */u/ but gaining the new consonants /kʲ/ and /kʷ/. The linguist John Colarusso has further postulated that some instances of this may also be due to the levelling of an old grammatical class prefix system (so */w-ka/ may have become /kʷa/), on the basis of pairs like Ubykh /ɡʲə/ vs. Kabardian and Abkhaz /ɡʷə/ heart. This same process is claimed by some to lie behind the development of labiovelars in Proto-Indo-European which once neighboured Proto-NWC.
Northwest Caucasian languages have rather simple noun systems, manifesting only a handful of cases at the most, coupled with highly agglutinative verbal systems so complex that virtually the entire syntactic structure of the sentence is contained within the verb. All finite verbs are marked for agreement with three arguments: absolutive, ergative and indirect object, and there are also a wide range of applicative constructions. There is a split between "dynamic" and "stative" verbs, with dynamic verbs having an especially complex morphology.
They do not generally permit more than one finite verb in a sentence, which precludes the existence of subordinate clauses in the Indo-European sense; equivalent functions are performed by extensive arrays of nominal and participial non-finite verb forms (although Abkhaz appears to be developing limited subordinate clauses, perhaps under the influence of Russian).
Circassian (or Cherkess) is a cover term for the series of dialects that include the literary languages of Adyghe and Kabardian.
The Adyghe (Adyge, Adyg) language is one of the more widely spoken Northwest Caucasian languages. It has 500,000 speakers spread throughout Russia and the Middle East: 280,000 in Turkey; 125,000 in Russia, where it is official in the Republic of Adygea; 45,000 in Jordan, 25,000 in Syria, 20,000 in Iraq, and 4,000 in Israel. There is even a small community in the United States. Four main dialects are recognised: Temirgoy, Abadzekh, Shapsugh and Bzhedugh, as well as many minor ones such as Hakuchi spoken by the last speakers of Ubykh in Turkey. Adyghe has a large number of consonants: between fifty and sixty consonants in the various Adyghe dialects but it has only three phonemic vowels. Its consonants and consonant clusters are less complex than the Abkhaz–Abaza dialects.
Kabardian has just over one million speakers: 550,000 in Turkey and 450,000 in Russia, where it is an official language of the republics of Kabardino-Balkaria and Karachay–Cherkessia. Kabardian has the least number of consonants of any North-Western Caucasian language, with 48, including some rather unusual ejective fricatives and a small number of vowels. Kabardian itself has several dialects, including Terek, the literary standard, and Besleney, which is intelligible with both Terek and Adyghe. Unlike the Adyghe, Kabardian lost many of the consonants that existed in the Proto-Circassian language, for example the consonants /ʃʷʼ/ /ʐʷ/ /ʂʷ/ /ʐ/ /ʂ/ /tsʷ/ /dzʷ/ became /fʼ/ /v/ /f/ /ʑ/ /ɕ/ /f/ /v/.
The Abkhaz (Abxaz) language has 100,000 speakers in Abkhazia (a de facto independent republic, but a de jure autonomous entity within Georgia), where it is the official language, and an unknown number of speakers in Turkey. It has been a literary language from the beginning of the 20th century. Abkhaz and Abaza may be said to be dialects of the same language, but each preserves phonemes which the other has lost. Abkhaz is characterised by unusual consonant clusters and one of the world's smallest vowel inventories: It has only two distinctive vowels, an open vowel /a/ and a mid vowel /ə/. Next to palatalized or labialized consonants, /a/ is realized as [e] or [o], and /ə/ as [i] or [u]. There are three major dialects: Abzhuy and Bzyp in Abkhazia and Sadz in Turkey.
The Abaza language has some 45,000 speakers, 35,000 in Russia and 10,000 in Turkey. It is a literary language, but nowhere official. It shares with Abkhaz the distinction of having just two phonemic vowels. Abaza is phonologically more complex than Abkhaz, and is characterised by large consonant clusters, similar to those that can be found in Georgian. There are three major dialects, Tapant and Ashkhar. Some are partially intelligible with Abkhaz.
The Ubykh language forms a third branch, despite its parallels with Adyghe and Abkhaz. The population switched to speaking Adyghe, and Ubykh became extinct on October 7, 1992, with the death of Tevfik Esenç. A dialectal division within Ubykh was suspected by Georges Dumézil, but the divergent form he described in 1965 was never investigated further. With eighty-one consonants, Ubykh has one of the largest inventories in the world, and probably the largest outside the Khoisan languages. There are pharyngealised consonants and a four-way place contrast among sibilants. It was the only Northwest Caucasian language never to have a literary form.
A number of factors make the reconstruction of the Northwest Caucasian proto-language problematic:
For these reasons, Proto–Northwest Caucasian is widely accepted as being one of the most difficult proto-languages to deal with, and it is therefore more difficult than most to relate to other families.
Some scholars have seen affinities between the Northwest Caucasian (Circassian) family and the extinct Hattic language. Hattic was spoken in Anatolia (Turkey), in the area around ancient Hattusa (modern Boğazköy), until about 1800 BC, when it was replaced by the Indo-European Hittite language. The name Hetto-Iberian (or Proto-Iberian) was proposed by Georgian historian Simon Janashia for a superfamily comprising the South Caucasian languages, other Caucasian language groups, Hattic and other languages of ancient Anatolia. (The Iberian in the name refers to Caucasian Iberia, a kingdom centered in Eastern Georgia which lasted from the 4th century BC to the 5th century AD; it is not related to the Iberian Peninsula.)
Many Northwest Caucasian (Adygean) family names have prefixes like "Hath" or "Hatti", and one of the well known Adyghe tribes has the name "Hattiqwai" (Adyghe: Хьатыкъуай) (From Хьаты (“Hatti”) + Кхъуэ (“male or son”); meaning “HattiSon”).
It has been conjectured that the North-West Caucasian languages may be genetically related to the Indo-European family, at a time depth of perhaps 12,000 years before the present. This hypothesised proto-language is called Proto-Pontic, but is not widely accepted.
There does at least appear to have been extensive contact between the two proto-languages, and the resemblances may be due to this influence.
Many linguists join the Northwest and Northeast Caucasian languages into a North Caucasian family, sometimes simply called Kavkazian (in opposition to Kartvelian (South Caucasian), which is thought to be unrelated, albeit heavily influenced by their northern neighbours). This hypothesis has perhaps been best illustrated by Sergei A. Starostin and Sergei Nikolayev, who present a set of phonological correspondences and shared morphological structure. However, there is no consensus that the relationship has been demonstrated, and many consider the correspondences to be spurious for the reasons mentioned above. See the article on North Caucasian languages for details, as well as the external links below.
A few linguists have proposed even broader relationships, of which the Dene–Caucasian hypothesis is perhaps the most popular. Dene–Caucasian links the North Caucasian (including Northwest Caucasian), Basque, Burushaski, Yeniseian, Sino-Tibetan, and Na–Dene families. However, this is an even more tentative hypothesis than Nostratic, which attempts to relate Indo-European, Uralic, Kartvelian, Altaic, etc., and which is widely considered to be undemonstrated.
