Coeur d'Alene: Lake and town in Kootenai County, Idaho; named from a tribe of Indians. French name, meaning "needle hearts" or "awl hearts." Some authorities say that this name was given to these Indians because the expression was used by a chief of the tribe to denote his opinion of the trappers' meanness. Rev. M. Eells says that the name was given to the tribe by members of the Hudson Bay Company, because of their sharpness in trade.
