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.
Shakori
The Shakori were associated with other Siouan tribes of the Piedmont, such as the Sissipahaw and Eno, and they all are believed to have spoken the same Siouan language. Scholars debate whether the Shakori, Eno, and Sissipahaw were different tribes or bands of the same tribe. This distinction became moot as the tribes merged with one another as their numbers decreased. Although they merged into remnants of other tribes and the larger Catawba, their Siouan dialect survived as late as 1743 among the Eno. They resisted Catawba assimilation the longest.
