Languages of the Caucasus

The Caucasian languages are a large and extremely varied array of languages spoken by more than ten million people in and around the Caucasus Mountains, which lie between the Black Sea and the Caspian Sea.

Linguistic comparison allows these languages to be classified into several language families, with little or no discernible affinity to each other. However, the languages of the Caucasus are sometimes mistakenly referred to as a family of languages.

Three of these families have no current members outside the Caucasus, and are considered indigenous to the area. The term Caucasian languages is generally restricted to these families, which are spoken by about 11.2 million people.

It is commonly believed that all Caucasian languages have a large number of consonants. While this is certainly true for most members of the Northeast and Northwest Caucasian families (inventories range up to the 80–84 consonants of Ubykh), the consonant inventories of the South Caucasian languages are not nearly as extensive, ranging from 28 (Georgian) to 30 (Laz) – comparable to languages like Arabic (28 consonants), Western European languages (20–21), and Russian (35–37 consonants).

The autochthonous languages of the Caucasus share some areal features, such as the presence of ejective consonants and a highly agglutinative structure, and, with the sole exception of Mingrelian, all of them exhibit a greater or lesser degree of ergativity. Many of these features are shared with other languages that have been in the Caucasus for a long time, such as Ossetian (which has ejective sounds but no ergativity).

Since the birth of comparative linguistics in the 19th century, the riddle of the apparently isolated Caucasian language families has attracted the attention of many scholars, who have endeavored to relate them to each other or to languages outside the Caucasus region. The most promising proposals are connections between the Northeast and Northwest Caucasian families and each other or with languages formerly spoken in Anatolia and northern Mesopotamia.
