The incredible complexity of the Caucasus's hidden linguistic treasures

In short: While English relies on a modest set of sounds, some Northeast Caucasian languages boast up to 70 distinct consonants. These languages, spoken across the Russian republics of Dagestan, Chechnya, and Ingushetia, hide a sophisticated architecture of grammar and sound that challenges our understanding of human speech.

The Northeast Caucasian language family—also known as East Caucasian or Nakh-Daghestanian—is a masterclass in phonological density. While researchers once believed these languages had smaller sound inventories than their Northwest Caucasian neighbors, recent studies have revealed a much richer reality. Some languages in this group contain as many as 70 consonants, utilizing complex features like ejective, tense, and pharyngeal sounds. While many of these languages have relatively few vowels, Chechen stands out as an exception, possessing at least twenty-eight vowels, diphthongs, and triphthongs.

The grammar of these languages is equally intricate, characterized by strong suffixal agglutination and a system of noun classes ranging from two to eight. Many exhibit an ergative-absolutive morphology, a system where the subject of an intransitive sentence is treated the same as the object of a transitive one. This complexity extends to 'external agreement,' a rare phenomenon where agreement markers appear on unexpected parts of speech, such as adverbs or even case-marked pronouns.

The origins of this family remain a subject of intense scholarly debate. Some linguists, including Igor M. Diakonoff and Sergei Starostin, have proposed genealogical links to the extinct Hurrian and Urartian languages, which were spoken in the Fertile Crescent and around Lake Van between the 3rd millennium BC and 585 BC. Furthermore, the presence of reconstructed terms for yokes, apples, and pears suggests that the ancestors of these speakers may have been early participants in the development of agriculture in the Fertile Crescent before migrating north to the Caucasus.
