The Eskaleut languages, also known as the Eskimo-Aleut or Inuit-Yupik-Unangan, denotes a family of languages spoken in Greenland, the arctic region of North America, and in the far eastern regions of Russia. Linguists count two main branches of the family, Eskimoan and Aleut, which split about 4000 years ago. The former is further divided into two groups: the Inuit and the Yupik languages. The latter contains just one language – Aleut, or Unangam Tunuu, spoken on the Aleutian Islands. The Inuit languages are spoken on Greenland and in the arctic regions of North-America, while the Yupik languages span across the Bering strait – spoken in Alaska and in the far-eastern regions of Russia.
