Manitou... (can be spelled Man'ito). Known as such, not only by Algonquin's but most tribes either living or originating in the Great Lakes region of the U.S. Because of the early French fur traders, this spelling and pronunciation is most widely used...
hence, in Canada we have the province of Manitoba and Manitoulin Island, the largest island in the world located in a lake; both take their name from Manitou.
