What tribe speaks the siouan language?

The Siouan language family is spoken by a number of tribes, not just one. Some of the major tribes speaking Siouan languages include:

* Dakota (Lakota and Nakota): Found primarily in the Great Plains region of North America.

* Omaha

* Osage

* Kansa

* Ponca

* Quapaw

* Catawba (Eastern Siouan)

* Tutelo (Eastern Siouan)

It's important to note that the Siouan language family is quite diverse, with a number of different branches and languages within it.

If you are interested in learning more about a specific Siouan tribe or language, I recommend doing some research on the individual tribe's history and culture.
