In 1978, Douglas R. Parks, David S. Rood, and Raymond J. DeMallie engaged in systematic linguistic research at the Sioux and Assiniboine reservations to establish the precise dialectology of the Sioux language. They ascertained that both the Santee and the Yankton/Yanktonai referred (and refer) to themselves by the autonym "Dakota." The name of "Nakota" (or "Nakoda") was (and is) exclusive usage of the Assiniboine and of their Canadian relatives, the Stoney. The subsequent academic literature, however, especially if it is not produced by linguistic specialists, has seldom reflected Parks and DeMallie's work.
