Munsee (also known as Munsee Delaware, Delaware, Ontario Delaware) is an
endangered language of the
Eastern Algonquian subgroup of the
Algonquian language family, itself a branch of the
Algic language family. Munsee is one of the two
Delaware languages. It is very closely related to the extinct
Unami Delaware, but the two are sufficiently different that they are considered separate languages. Munsee was spoken aboriginally in the vicinity of the modern
New York City area in the
United States, including western
Long Island,
Manhattan Island,
Staten Island, as well as adjacent areas on the mainland:
southeastern New York State, the northern third of
New Jersey, and northeastern
Pennsylvania.
