Unami is an Algonquian language spoken by Lenape people in what was then the lower Hudson Valley area and New York Harbor area, New Jersey, Pennsylvania and Delaware, but later in Ontario and Oklahoma. It is one of the two Delaware languages, the other being Munsee. The last fluent speaker in the United States, Edward Thompson, of the Delaware Tribe of Indians, died on 31 August 2002. His sister Nora Thompson Dean (1907–1984) provided valuable information about the language to linguists and other scholars.
