History

The Alaska Native Language Center believes that the common ancestral language of the Eskimoan languages and of Aleut divided into the Eskimoan and Aleut branches at least 4,000 years ago. The Eskimoan language family split into the Yupik and Inuit branches around 1,000 years ago.

The Eskaleut languages are among the native languages of the Americas. This is a geographical category, not a genealogical one. The Eskaleut languages are not demonstrably related to the other language families of North America and are believed to represent a separate, and the last, prehistoric migration of people from Asia.

Alexander Vovin (2015) notes that northern Tungusic languages, which are spoken in eastern Siberia and northeastern China, have Eskaleut loanwords that are not found in Southern Tungusic, implying that Eskaleut was once much more widely spoken in eastern Siberia. Vovin (2015) estimates that the Eskaleut loanwords in Northern Tungusic had been borrowed no more than 2,000 years ago, which was when Tungusic was spreading northwards from its homeland in the middle reaches of the Amur River. Vovin (2015) considers the homeland (Urheimat) of Proto-Eskaleut to be in Siberia rather than in Alaska.
