The Chinookan languages are a family of Native American languages spoken by the Chinook and other tribes in the Pacific Northwest region of the United States. This language family includes several dialects, such as Chinook Jargon, which served as a trade language among various tribes and European settlers. Chinookan languages are known for their unique phonetic features and complex grammar. They have been influenced by contact with other languages, including English and French. Today, efforts are being made to revitalize these languages, as many speakers have diminished over the years.
