The Cheyenne language (Tsėhesenėstsestȯtse, [tse̥hésene̥stsesto̥tse], informal spelling Tsisinstsistots) is the Native American language spoken by the Cheyenne people, predominantly in present-day Montana and Oklahoma, in the United States. It is part of the Algonquian language family. Like all other Algonquian languages, it has complex agglutinative polysynthetic morphology. This language is considered endangered, at different levels, in both states.
