The Siouan languages are a family of Native American languages primarily spoken in the central United States. This language family includes several languages, such as Lakota, Dakota, and Crow. These languages are known for their complex grammatical structures and rich oral traditions, reflecting the cultures of the tribes that speak them. Siouan languages are part of a larger linguistic classification that connects various indigenous groups. They are primarily spoken by tribes in regions like the Great Plains and the Southeastern United States. Efforts are ongoing to preserve and revitalize these languages, as many are endangered due to declining numbers of speakers.
