i'm quite certain this is going to come out exactly as garbled as it is in my mind, but i'll attempt this query:

In the case of 'chagrined' as a verb, as in atomica's example, 'He was chagrined at the poor sales of his book', we label 'chagrined' a verb. this suggests that if we were to replace 'chagrined' with disappointed, mortified, saddened, elated, pleased, etc., they would all be considered verbs. If we said, then, that "He was happy with his book sales", what part of speech would happy be? i'm sure this is basic grammar to most of you, but i'm at a loss. Furthermore, what part of speech is "was"? i was thinking it would be a transitive verb, but a google search suggests that i'm wrong. Also, what part of speech, specifically, would 'chagrined' be in the example cited above? a verbal object of some sort?

TIA
