Many members of the Oceti Sakowin prefer the ethnonyms Dakota, Nakota, and Lakota because the name "Sioux" is an exonym—a name bestowed by outsiders—that carries negative connotations.12

The term "Sioux" is a shortening of the French nadouessioux, which is derived from an Ojibwe word often translated as "little snakes" or "adders". This name was originally used by traditional rivals of the Oceti Sakowin to describe them as enemies. In contrast, the names Dakota, Nakota, and Lakota are self-designated terms that refer to the three dialects of their language and translate to "friendly" or "ally".314

Despite these preferences, "Sioux" remains in common use for several practical reasons: it serves as a convenient collective referent for the three dialect groups, it is embedded in historical and linguistic terminology (such as Siouan languages), and it promotes ethnic solidarity. Furthermore, because many tribes are legally recognized under the name Sioux, changing official titles is a complex process that can divert resources from other social and political priorities. Consequently, many groups use both names to reflect their heritage and their legal status.1
