The Khoisan languages are a number of African languages once classified together, originally by Joseph Greenberg. Khoisan is defined as those languages that have click consonants and do not belong to other African language families. For much of the 20th century, they were thought to be genealogically related to each other, but this is no longer accepted. They are now held to comprise three distinct language families and two language isolates.
The term Ibero-Caucasian was proposed by Georgian linguist Arnold Chikobava for the union of the three language families that are specific to the Caucasus mountains region of Eurasia.
The Northwest Caucasian languages, also called West Caucasian, Abkhazo-Adyghean, Abkhazo-Circassian, Circassic, or sometimes Pontic languages, is a family of languages spoken in the northwestern Caucasus region, chiefly in three Russian republics, the disputed territory of Abkhazia, Georgia, and Turkey, with smaller communities scattered throughout the Middle East.
The Northeast Caucasian languages, also called East Caucasian, Nakh-Daghestani or Vainakh-Daghestani, or sometimes Caspian languages, is a family of languages spoken in the Russian republics of Dagestan, Chechnya and Ingushetia and in Northern Azerbaijan as well as in Georgia and diaspora populations in Western Europe and the Middle East. According to Glottolog, there are currently 36 Nakh-Dagestanian languages.
The Nakh languages are a group of languages within the Northeast Caucasian family, spoken chiefly by the Chechens and Ingush in the North Caucasus.
A sprachbund, also known as a linguistic area, area of linguistic convergence, or diffusion area, is a group of languages that share areal features resulting from geographical proximity and language contact. The languages may be genetically unrelated, or only distantly related, but the sprachbund characteristics might give a false appearance of relatedness.
Ubykh is an extinct Northwest Caucasian language once spoken by the Ubykh people, a subgroup of Circassians who originally inhabited the eastern coast of the Black Sea before being deported en masse to the Ottoman Empire in the Circassian genocide.
Abkhaz, also known as Abkhazian, is a Northwest Caucasian language most closely related to Abaza. It is spoken mostly by the Abkhaz people. It is one of the official languages of Abkhazia, where around 190,000 people speak it. Furthermore, it is spoken by thousands of members of the Abkhazian diaspora in Turkey, Georgia's autonomous republic of Adjara, Syria, Jordan, and several Western countries. 27 October is the day of the Abkhazian language in Georgia.
The North Caucasian languages, sometimes called simply Caucasic, is a proposed language family consisting of a pair of well established language families spoken in the Caucasus, predominantly in the north, consisting of the Northwest Caucasian family and the Northeast Caucasian family. There are some 34 to 38 distinct North Caucasian languages.
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives.
Na-Dene is a family of Native American languages that includes at least the Athabaskan languages, Eyak, and Tlingit languages. Haida was formerly included but is now considered doubtful. By far the most widely spoken Na-Dene language today is Navajo, also the most spoken indigenous language north of Mexico.
The Alarodian languages are a proposed language family that encompasses the Northeast Caucasian (Nakh–Dagestanian) languages and the extinct Hurro-Urartian languages.
The Yeniseian languages are a family of languages that are spoken by the Yeniseian people in the Yenisei River region of central Siberia. As part of the proposed Dené–Yeniseian language family, the Yeniseian languages have been argued to be part of "the first demonstration of a genealogical link between Old World and New World language families that meets the standards of traditional comparative-historical linguistics". The only surviving language of the group today is Ket.
Hurro-Urartian is an extinct language family of the Ancient Near East, comprising only two known languages: Hurrian and Urartian.
Svan is a Kartvelian language spoken in the western Georgian region of Svaneti primarily by the Svan people. With its speakers variously estimated to be between 30,000 and 80,000, the UNESCO designates Svan as a "definitely endangered language". It is of particular interest because it has retained many features that have been lost in the other Kartvelian languages.
Bats, also known as Batsbi, Batsi, Batsb, Batsaw, or Tsova-Tush) is the endangered language of the Bats people, a North Caucasian minority group living in the Republic of Georgia. Batsbi is part of the Nakh branch of Northeast Caucasian languages. It had 2,500 to 3,000 speakers in 1975, with only one dialect. Batsbi is only used for spoken communication, as Bats people tend to use Georgian when writing.
Dené–Caucasian is a discredited language family proposal that includes widely-separated language groups spoken in the Northern Hemisphere: Sino-Tibetan languages, Yeniseian languages and Burushaski in Asia; Na-Dené languages in North America; as well as Vasconic languages and North Caucasian languages from Europe.
Abkhaz is a language of the Northwest Caucasian family which, like the other Northwest Caucasian languages, is very rich in consonants. Abkhaz has a large consonantal inventory that contrasts 58 consonants in the literary Abzhywa dialect, coupled with just two phonemic vowels.
The Kartvelian languages are a language family indigenous to the South Caucasus and spoken primarily in Georgia. There are approximately 5 million Georgian language speakers worldwide, with large groups in Russia, Iran, the United States, the European Union, Israel, and northeastern Turkey. The Kartvelian family has no known relation to any other language family, making it one of the world's primary language families.
Chamalal is an Andic language of the Northeast Caucasian language family spoken in southwestern Dagestan, Russia by approximately 5,100 ethnic Chamalals. It has three quite distinct dialects, Gadyri, Gakvari, and Gigatl.
