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."
