The Chukotko-Kamchatkan language family consists of languages spoken primarily in the northeastern regions of Russia, particularly in Chukotka and the Kamchatka Peninsula. This family includes two main branches: Chukchi, spoken by the Chukchi people, and Koryak, spoken by the Koryak people. These languages are known for their complex grammatical structures and rich vocabulary related to the environment. Chukotko-Kamchatkan languages are considered endangered, with a declining number of speakers due to cultural and social changes. Efforts are being made to preserve these languages through education and documentation, highlighting their importance to the cultural heritage of the indigenous peoples of Siberia.
