Siouan languages
Authors who call the entire family "Siouan" distinguish the two branches as "Western Siouan" and "Eastern Siouan" or as "Siouan-proper" and "Catawban". Others restrict the name "Siouan" to the western branch and use the name "Siouan–Catawban" for the entire family. Generally, however, the name "Siouan" is used without distinction.
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.
