Eskimo is an exonym, although within Alaska, the term is used by both indigenous and non-indigenous Alaskans. The most widely accepted academic etymology for the term posits an original meaning of "to net snowshoes."[2][3] Within Canada, the term is considered derogatory, and "Inuit" is preferred. The terms "Yup'ik", "Yupik", and "Inupiaq" are also used in Alaska to refer to these respective groups.
The Eskimo language family is divided into the Inuit and Yup'ik groups. The proper place of Sirenik within the Eskimo-Aleut language family is debated. Some linguists list it as a branch of Yupik[4], while others list it as a distinct branch of the language family[5].
According to Joseph Greenberg's highly controversial classification of the languages of Native North America, Eskimo-Aleut is one of the three main groups of Native languages spoken in the Americas, and represents a distinct wave of migration from Asia to the Americas. The other two are Na-Dené (which includes Athabaskan and a small number of related tongues) and Amerind (Greenberg's most controversial classification, which includes every language native to the Americas that is not Eskimo-Aleut or Na-Dené).
