Ubykh, an extinct Northwest Caucasian language, has the largest consonant inventory of all documented languages that do not use clicks, and also has the most disproportional ratio of phonemic consonants to vowels.

Ubykh is an extinct Northwest Caucasian language once spoken by the Ubykh people, an ethnic group of Circassian nation who originally inhabited the eastern coast of the Black Sea before being deported en masse to the Ottoman Empire in the Circassian genocide.

There has never been a standard written form of Ubykh, though there was a rich oral literature, some of which has been transcribed using a mixture of the IPA and the Latin alphabet. The Ubykh people themselves have shown interest in relearning their language, which include more consonants then just about any other language and very few vowels.

Ubykh or Ubyx is a language of the Northwestern Caucasian group, spoken by the Ubykh people up until the early 1990s. The word is derived from IPA|/wəbəx/, its name in the Abdzakh Adyghe (Circassian) language.

An IPA rendition of the Ubykh consonant system is available in the Ubykh phonology article. All but three of the 83 consonants are found in native vocabulary. The plain velars [] are found only in loans: crow (from Turkish), slat, batten (from Abdzakh Adyghe), estate, legacy .
