The Otoe language is a member of the Siouan language family, primarily spoken by the Otoe-Missouria Tribe in the United States. It is considered a critically endangered language, with very few fluent speakers remaining. Efforts are being made to revitalize the language through educational programs and community initiatives. Otoe is closely related to other Siouan languages, such as Missouria and Dakota. The language features unique phonetic and grammatical structures, reflecting the cultural heritage of the Otoe people. Preservation of the Otoe language is vital for maintaining the tribe's identity and traditions.
