•
Chukchi, spoken mostly within
Chukotka Autonomous Okrug. •
Koryak, also called Nymylan, spoken in
Koryak Okrug of
Kamchatka Krai. The main dialect is known as Chavchuven Koryak. •
Alyutor (Alutor, Aliutor), also spoken in Koryakia. •
Kerek, spoken along the southern coast of Chukotka. In 1997 two elderly speakers remained, but now the language is extinct, with the ethnic group assimilated into the Chukchi (Fortescue 2005: 1). Traditionally, Chukotkan was considered to be two languages, Chukchi and Koryak, due to a sharp ethnic division between the
Chukchi and
Koryak people. However, the Kerek and Alyutor dialects, spoken by ethnic Chukchi and Koryak, are as different from those varieties as they are from each other. Thus Chukotkan is currently generally classified as four languages, but it could as easily be considered one language with significant dialectal variation. ==Further reading==
