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.
Nakota
Recently the Assiniboine and, especially, the Stoney have begun to minimize the historic separation from the Dakota. They have claimed some identity with the Sioux nation, although such a centralized unit no longer exists. Historically, the Siouan tribes were quite decentralized as well and operated independently in bands. The tendency can be seen on Alberta's Stoney official Internet sites, for example, in the self-designation of the "Alexis Nakota "Sioux" First Nation", or in the claim of the "Nakoda First Nation" to their Sioux ancestry and the value of their native language:
"As descendants of the great Sioux nations, the Stoney tribal members of today prefer to conduct their conversation and tribal business in the Siouan mother tongue". Saskatchewan's Assiniboine and Stoney tribes also claim identification with the Sioux tradition.
