Regards the 'Geoduc' ( Fisheries Resource spelling) . . .it is not from Chinook jargon, that is, there are no words in the Chinook jargon that are even close to 'Gooey' or 'Kwee' nor are any close to 'Duc' or 'Duck' The Geoduc is not distinct from the Horse Clam in the jargon ( both are large Pacific northwest clams whose shells are quite different but the protruding siphons are similar - Geoduc siphons are 'fringed' while Horse clams are smooth) the word for either of these in Chinook is 'Mamook Smetocks' Only other clam names are 'Mamook ona' ( Razor clam) and 'Mamook lukutchee' ( Littleneck) For those unfamiliar with Chinook jargon, it was/is a 'Lingua Franca' or trade language spoken from Southern Oregon to Alaska . It was comprised of words from the Salish, Kwak'wakawakw ( ex- Kwakiutl) and Nuchalnath ( ex- Nootka) After contact, a number of English and French derived words were added, primarily to cover off things that hadn't existed before. It took the early explorers a relatively long time to figure out that each educated native spoke at least two distinct languages - that of their home village and Chinnok jargon - a sort of early Esperanto. The Chinook people lived around the mouth of the Columbia River and oral tradition has it that they conceived of this system which was named for them and contained a large number of Chinook words. More than you wanted to know, probably! 'Geoduc" is not in Kwak'wala (Kwakiutl Lang.) nor Wakashan (Nootka Lang.) I doubt it is Chinook since it would be in the Chinook jargon if it were. It may be Salish, but it doesn't 'sound' Salish. So where does it come from??? Good question . . .which is not even slightly closer to being answered even after all this log-windedness. I will check on the Salish and report back. Regards from British Columbia!
