Siouan languages
Siouan languages can be grouped into the Western Siouan languages and Catawban languages. The Western Siouan languages can be divided into Missouri River languages (such as Crow and Hidatsa), Mandan, Mississippi River languages (such as Dakotan, Chiwere-Winnebago, and Dhegihan languages), and Ohio Valley Siouan branches. The Catawban languages consist only of Catawban and Woccon.
Waccamaw
Very little remains of the Waccamaw's ancestral Woccon language today, it was one of the two Catawban branches of the Siouan language family. The language was lost due to devastating population losses and social disruptions during the eighteenth and nineteenth centuries. It is attested today in a vocabulary of 143 words, printed in 1709.
