central Algonquian people who lived near the upper Mississippi before the Black Hawk War of 1832, from French Canadian Saki, probably a shortened borrowing of Ojibwa (Algonquian) /osa:ki:/, literally "person of the outlet" (of the Saginaw River, which itself contains their name, and means literally "in the Sauk country").
