My friend, FireSong, sent me this Chinook Dictionary link and it has a lot to offer so I
wanted to share it with you all. She shared that "the Chinook dialect predates English or Spanish inhabitants of the Americas and that the "Chinook
Jargon" was developed with the influence of English and French traders and missionaries. It was the most common language used between Native Americans
and whites on the West Coast from BC down through California in trade, intertribal, fishing and other industry or commerce type situations and eventually
replaced the original "Old Chinook" dialects (of which there were over 100 in the Pacific NW mainly along the Columbia and Willamet Rivers."
