A Siouan languages come the Native American language family of North America. A Siouan personal is related to the Catawban languages. When a Lakota, Dakota, and Nakota comprise "the Great Sioux Nation", a language personal is very much wide & includes "the old speakers", a Hocák (Winnebago) and their linguistic full cousin, a Absaroke (Crow). A Siouan personal as well extends back East and down South.

When social migrations own eventually to exist as definitively worked out, linguistic & historical sitings imply the southern origin of Siouan humans, by using migrations on top the thousand years ago from either North Carolina and Virginia to Ohio, then each down the Ohio River to the Mississippi and up to a Missouri, and through Ohio to Illinois, Wisconsin and Minnesota, home of the Dakota. Occasionally linguists associate Siouan languages by using Caddoan and Iroquoian languages in the Macro-Siouan language family.
