The term "Chinookan" refers to a group of Indigenous peoples and their languages primarily located in the Pacific Northwest region of the United States. This group includes tribes such as the Chinook, Clatsop, and Wasco, who historically lived along the Columbia River and its tributaries. The Chinookan languages are part of the larger Penutian language family, characterized by their unique phonetic and grammatical structures. Chinookan culture is rich in traditions, including fishing, hunting, and gathering, which were essential for their sustenance.
