Lakota (also Lakhota, Teton, Teton Sioux) is a Siouan language spoken by the Lakota people of the Sioux tribes. Though generally taught and considered by speakers as a separate language, Lakota is mutually intelligible with the other two languages (cf. Dakota language), and is considered by most linguists one of the three major varieties of the Sioux language. The Lakota language represents one of the largest Native American language speech communities in the United States, with approximately 6,000 speakers living mostly in northern plains states of North Dakota and South Dakota. There is a Lakota language program online available for children to use. There is also a Lakota Language Program with classes for children at Red Cloud Indian School.
