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.
Assiniboine language
The Assiniboine language (also known as Assiniboin, Hohe, or Nakota, Nakoda, Nakon or Nakona, or Stoney) is a Nakotan Siouan language of the Northern Plains. The name Assiniboine comes from the term "Asiniibwaan", from Ojibwe, meaning "Stone Siouans". The reason they were called this was that Assiniboine people used heated stone to boil their food. In Canada, Assiniboine people are known as Stoney Indians, while they called themselves Nakota or Nakoda, meaning "allies""."
