Sahaptian is a language family encompassing several distinct languages, including Nez Perce, Umatilla, and Walla Walla. The Yakama dialect is closely related to the Klickitat dialect spoken by the Klickitat tribe.
It's important to note that while Sahaptian languages were historically spoken by a wide range of tribes in the Pacific Northwest, their use has significantly declined in recent decades due to various factors like forced assimilation, cultural suppression, and intermarriage.
However, there are ongoing efforts to revitalize and preserve these languages, including language immersion programs and community-based initiatives.
