Nez Perce people
The word "Sahaptin/Shahaptin" is not the one used by the tribes that speak it, but from the Columbia Salish name, Sħáptənəxw / S-háptinoxw, which means "stranger in the land". This is the name the Wenatchi (in Sahaptin: Winátshapam) and Kawaxchinláma (who speak Columbia Salish) traditionally call the Nez Perce people. Early white explorers mistakenly applied the name to all the various Sahaptin speaking people, as well as to the Nez Perce. Sahaptin is spoken by various tribes of the Washington Reservations; Yakama, Warm Springs, Umatilla; and also spoken in many smaller communities such as Celilo, Oregon.
