Oh, we have the same thing -- sorcerers have innate magical power which they learn to control with practice, as opposed to formalized study to learn how to do that same sort of thing.

To be honest, wizards often look down on sorcerers, out of a belief that what they earned by hard work, sorcerers just possess naturally, which somehow makes the wizard way superior. [The roll of eyes which accompanies this statement ought to make Roy's opinion on the matter perfectly clear.]
