see sake (n.2).

Japanese city, named for its situation, from naga "long" + saki "headland, promontory."

central Algonquian people who lived near the upper Mississippi before the 1832 Black Hawk War, 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 Sac country").
