Cheyenne people
The Cheyenne (/ʃaɪˈæn/ shy-AN) are a people of the Great Plains. The language they use, the Cheyenne language, is part of the Algonquian language group. Now, the Cheyenne people are broken into two nations seen by the government: the Southern Cheyenne, who are part of the Cheyenne and Arapaho Tribes in Oklahoma, and the Northern Cheyenne, who represent the Northern Cheyenne Tribe of the Northern Cheyenne Indian Reservation in Montana. The Cheyenne comprise two Native American tribes, the Só'taeo'o or Só'taétaneo'o (usually spelled as Suhtai or Sutaio) and the Tsétsêhéstâhese (also spelled as Tsitsistas, like [t͡sɪt͡shɪstʰɑs]). The tribes connected in the early 19th century.
