Not using those terms, but yes they would (or certainly could):
Jacinda: "I've been doing some research and found there's casters out there who don't need to memorize their spells - they just cast 'em whenever they want until they exhaust themselves and need to rest. I'm'a learn how to do that!"
Falstaff: "You know, after all this time watching Rochelle sneaking around and doing her thing, I'm thinking it might be an idea if I learned at least the basics of what she does - provided she's willing to teach me, that is. Obviously I'll never be as good at it as she is, but if it can help me get into better position before the fighting starts, I'm all for it! That, and if I learn anything about how to climb walls then maybe you lot won't have to keep hauling my ass out of all the pits I fall into."
