The Ubykh language is a Northwest Caucasian language that was historically spoken by the Ubykh people in the region of Abkhazia, now part of Georgia. It is known for its complex consonant system, featuring 84 distinct consonants, making it one of the languages with the highest consonant-to-vowel ratio in the world. Ubykh became extinct in 1992 with the death of its last fluent speaker, Tevfik Esenç. The language is notable for its rich oral tradition and has been the subject of linguistic studies due to its unique phonetic characteristics and grammatical structure.
