ok, words ending with -ch most likely have a negative connotation. grinch, pinch, bitch, wench. cinch is kind of sleazy ("hey! that was a cinch!" read: i blatantly cheated), and winch connotes (to me at least) the feeling of crushing one's fingers with a large metal object. i'm not sure about bench. or finch. damnit, there goes my elaborately constructed analysis of the english language. i'm going to go to bed now.
