The Siouan Language Family is a group of Native American languages primarily spoken in the central United States. This family includes languages such as Lakota, Dakota, and Osage. These languages are known for their complex grammatical structures and rich oral traditions. Siouan languages are historically significant and are associated with various Indigenous tribes. The family is divided into several branches, with some languages still actively spoken today, while others are endangered. Efforts are ongoing to revitalize and preserve these languages, reflecting the cultural heritage of the Sioux and other tribes.
