The Caucasian languages represent one of the most complex and fascinating linguistic groupings in the world. Spoken in and around the Caucasus region—situated between the Black Sea and the Caspian Sea—these languages are not only diverse in number but also extraordinary in their phonology, morphology, and syntax. Linguists generally divide Caucasian languages into three major families: South Caucasian (Kartvelian), Northwest Caucasian (Abkhazo-Adyghian), and Northeast Caucasian (Nakho-Dagestanian). Together, they are spoken by close to 12 million people, making them a significant yet often overlooked part of the world’s linguistic heritage.

Overall Total
All Caucasian languages combined: approximately 11.5–12 million speakers, concentrated in the Caucasus region with significant diaspora communities, especially in Turkey, the Middle East, and Europe.
The South Caucasian (Kartvelian) Language Family
The South Caucasian, or Kartvelian, language family consists of four closely related languages spoken by approximately five million people. These languages are Georgian, Svan, Mingrelian (Megrel), and Laz (Chan). Unlike the other Caucasian families, Kartvelian languages are found almost entirely south of the Caucasus mountain range.
Georgian: The Dominant Kartvelian Language
Among all Caucasian languages, Georgian stands out as the most widely spoken and culturally influential. It is the official language of Georgia and is used by the vast majority of the country’s population, with small Georgian-speaking communities in neighboring Turkey and Azerbaijan. Georgian is unique not only because of its number of speakers but also because it possesses an ancient written tradition, dating back more than 1,500 years. This makes it the only Caucasian language with a long-standing literary history.
Svan, Mingrelian, and Laz
The other Kartvelian languages are more regionally confined:
- Svan is spoken in the mountainous Svaneti region in northern Georgia.
- Mingrelian is found primarily in western Georgia’s lowland areas.
- Laz is spoken in northeastern Turkey, along a narrow strip of land bordering the southeastern coast of the Black Sea.
Although these languages are closely related to Georgian, they are not mutually intelligible with it and are often considered endangered due to their limited number of speakers and lack of standardized writing systems.
The Northwest Caucasian (Abkhazo-Adyghian) Language Family
The Northwest Caucasian, or Abkhazo-Adyghian, family includes four living languages spoken by around 2.3 million people, along with one extinct language. These languages are known for their extremely complex consonant systems and minimal vowel inventories.
Languages and Geographic Distribution
The major languages in this family are:
- Abkhaz, spoken south of the Caucasus range in Abkhazia
- Abaza, spoken in Karachay-Cherkessia
- Adyghe, spoken in Adygea
- Kabardian, spoken in Kabardino-Balkaria
All except Abkhaz are spoken primarily north of the Caucasus mountains.
The Extinct Ubykh Language
A notable member of this family is Ubykh, which became extinct in the late 20th century with the death of its last speaker. Ubykh is famous among linguists for having one of the largest consonant inventories ever recorded, with around 80 consonants and only a handful of vowels.
The Northeast Caucasian (Nakho-Dagestanian) Language Family
The Northeast Caucasian, also known as Nakho-Dagestanian, family is the largest and most internally diverse of the Caucasian language families. It is divided into two main subfamilies: Nakh and Dagestanian.
The Nakh Subfamily
The Nakh languages include Chechen, Ingush, and Bats, spoken by about 1.8 million people:
- Chechen is predominant in Chechnya
- Ingush is spoken mainly in Ingushetia
- Bats is confined to a single village in northeastern Georgia
Chechen and Ingush are closely related and share many grammatical features, while Bats is much smaller and highly endangered.
The Dagestanian Subfamily
The Dagestanian languages are spoken mainly in Dagestan and neighboring parts of Azerbaijan. They are further divided into three major groups:
- Avaro-Ando-Tsezic
Spoken in central and western Dagestan and northwestern Azerbaijan, this group includes Avar, the dominant language, along with many smaller languages such as Andi, Tsez (Dido), Hunzib, and Beztha. Most of these have fewer than 50,000 speakers each. - Lako-Dargwa
This group includes Lak and Dargwa, spoken by nearly 700,000 people in central Dagestan. - Lezgic
The Lezgic group is spoken by around one million people, mainly in southern Dagestan and northern Azerbaijan. Lezgi is the most widely spoken, followed by languages such as Tabasaran, Rutul, Tsakhur, and Aghul. Smaller languages like Udi, Archi, and Khinalugh have fewer than 10,000 speakers each.
Speakers and Language Status
Altogether, Caucasian languages are spoken by nearly 12 million people. However, many of these languages—especially smaller ones—are unwritten and endangered. Urbanization, migration, and the dominance of national languages such as Russian and Georgian have placed increasing pressure on minority languages.
Among all Caucasian languages, Georgian holds a unique position due to its official status, standardized writing system, and extensive literary tradition.
Main Linguistic Features of Caucasian Languages
Phonology
One of the most striking features of Caucasian languages is their rich consonant systems. Across all three families, stops and affricates typically show a three-way contrast:
- voiced
- voiceless aspirated
- voiceless glottalized (ejective)
In general, languages with very large consonant inventories tend to have small vowel systems, and vice versa.
- Abkhazo-Adyghian languages have extremely few vowels—often just a and schwa—but massive consonant inventories. Abkhaz and Adyghe have around 70 consonants, while Ubykh had about 80.
- Nakho-Dagestanian languages display more complex vowel systems, including long, nasalized, pharyngealized, and labialized vowels, alongside substantial consonant inventories.
- Kartvelian languages have a simpler five-vowel system (a, e, i, o, u). Svan is an exception, with additional front vowels and vowel length contrasts.
Morphology
The three families differ greatly in grammatical structure:
- Abkhazo-Adyghian languages have minimal or nonexistent case systems but extremely complex, polysynthetic verbs.
- Nakho-Dagestanian languages show the opposite pattern, with elaborate case systems and multiple grammatical genders, paired with relatively simple verbs.
- Kartvelian languages occupy a middle ground, with moderate case systems and richly inflected verbs that mark person, number, tense, aspect, mood, and voice.
Syntax
Despite their differences, Caucasian languages share several syntactic traits:
- Subject–Object–Verb (SOV) word order
- Ergative constructions
- The use of postpositions instead of prepositions
In Kartvelian and Nakh-Dagestanian languages, adjectives and genitives typically precede the noun, while in Abkhazo-Adyghian languages, adjectives usually follow the noun.

Lexicon and External Influences
Although much of the original vocabulary has been preserved, Caucasian languages have absorbed numerous loanwords over the centuries. Arabic, Persian, and Turkic languages have had significant influence, while Russian has contributed many technical and administrative terms in the north. In the south, Greek has played a similar role.
