 Pre-contact distribution of Caddoan languages | |
The Caddoan languages are a family of languages native to the Great Plains spoken by tribal groups of the central United States, from present-day North Dakota south to Oklahoma. All Caddoan languages are critically endangered, as the number of speakers has declined markedly due to colonial legacy, lack of support, and other factors.
