アルゴンキン語族
The languages of the Algonquian family constitute a group of historically related languages descended from a common source language, Proto-Algonquian, which was descended from Algic. The Algonquian languages are spoken across Canada from the Rocky Mountains to the Atlantic coast; on the American Plains; south of the Great Lakes; and on the Atlantic coast. Many of the Algonquian languages are now sleeping.
