Ok, thank you. Couple things. First, I'm not so sure your ex. of the the verb hang fits, here. I'm talking about common usage, not "correctness". We don't say, "He hanged the sign on the door", or, "The sign hanged on the door". It hung. He hung it. Or, he did hang it.

Next--thank you for pointing out the transitive/intransitive link. That's the kind of thing I wouldn't think of on my own. Coupled with pay, rise and raise are nouns, interestingly. And with self-, they become adjectives, though they're treated grammatically as verbs...I think.

Hmm...my pay rises, it doesn't raise. Self-r. flour causes bread to rise; it raises the dough while it's baking. Grammatically, it seems more correct to me to say pay rise, and self-rising flour.

Rise and raise can both be nouns, as used here. Maybe we say raise for an increase in salary ("I got a raise".) to differentiate by context from "I got a rise out of him". Funny--I absolutely canNOT stop a sentence at "I got a rise"; I HAVE to add the rest of the phrase.

Maybe we say pay raise to match the transitive "My boss raised my salary". We certainly wouldn't say "My boss rose my salary". Would anyone who would say "I got a pay rise" please post what you would say in place of raised, in "My boss raised my salary"? I'd be really interested to see.
