Eskimo
via French Esquimaux, possibly from Spanish esquimao, esquimal, from Montagnais ayas̆kimew ‘person who laces a snowshoe’, probably applied first to the Micmac and later to the Eskimo (see husky2).
wiktionary
Attested since 1584, [1] [2] ultimately from an Old Montagnais term. Ives Goddard's theory, accepted by most linguists today, is that it derives from Montagnais ayaškimew(“snowshoe-netter”). An older theory, defended by John Steckley due to its greater acceptance in Native oral traditions, but discredited [3] by linguists, is that it derives from a term meaning "eater(s) of raw meat".
etymonline
Eskimo (n.)
1580s, from Danish Eskimo or French Esquimaux (plural), both probably from an Algonquian word, such as Abenaki askimo (plural askimoak), Ojibwa ashkimeq, traditionally said to mean literally "eaters of raw meat," from Proto-Algonquian *ask- "raw" + *-imo "eat." Research from 1980s in linguistics of the region suggests this derivation, though widely credited there, might be inaccurate or incomplete, and the word might mean "snowshoe-netter," but there are phonological difficulties with this. See also Innuit. Of language, from 1819. As an adjective by 1744. Eskimo pie "chocolate-coated ice cream bar" was introduced in 1922 and was at first a craze that drove up the price of cocoa beans on the New York market 50 percent in three months [F.L. Allen, "Only Yesterday," 1931].
