One of the terms used to refer to some sort of creating force by the Natives of the Lower Columbia River basin. Usually translated, by white folklorists and amateurs earlier this century, as the "Great Spirit." While this rendering is pretty accurate, since Tyee does indeed mean 'great, big, large' and Sahale does mean something like 'spirit, soul, ghost' it does not address the larger issues regarding underlying nuance. As it stands, "Great Spirit" sounds like something out a 1950s Western, which is probably the wrong implication. And, indeed, whether this term is a relatively late coinage (after contact with white missionaries) or much earlier is something that is, as far as I know, unresolved.
