The Caddoan language family is a group of Native American languages primarily spoken by tribes in the Great Plains region of the United States. This family includes languages such as Caddo, Osage, and Pawnee. These languages share common linguistic features and are believed to have originated from a single ancestral language. Caddoan languages are known for their complex grammatical structures and rich oral traditions. They have been historically significant for the Caddo Nation and other tribes, playing a crucial role in their cultural identity. Efforts are ongoing to preserve and revitalize these languages among younger generations.
