The Komi-Yazva language (коми-ёдз көл, komi-jodz kål) is a Permic language closely related to Komi-Zyrian and Permyak, and spoken mostly in Krasnovishersky District of Perm Krai in Russia, in the basin of the Yazva (Yodz) River.

[2] About two thousand speakers densely live in Krasnovishersky District.Availability[clarification needed] of the particular vowels together with features of phonetics and stress system led Finnish linguist Arvid Genetz in 1889 to consider Komi-Yazva as a separate dialect.

[citation needed] Later, this decision was confirmed by the famous Finno-Ugricist Vasily Lytkin, who studied the Komi-Yazva idiom in depth from 1949 until 1953.

[citation needed] In the early 1960s, about 2,000 speakers lived compactly on the territory of Krasnovishersky District of Perm Krai (Antipinskaya, Parshakovskaya, Bychinskaya and Verkh-Yazvinskaya village administrations).

[3] The presence of special vowel sounds, specific phonetics and accent system allowed first Finnish linguist Arvid Genetz, who studied the people in 1889, and then the Finno-Ugric philologist Vasily Lytkin, who visited the Komi-Yazvinians three times between 1949 and 1953, to identify the Komi-Yazvinians as a separate dialect.
