Steve Pemberton's The Times & Life of Lucifer Jones describes the distinction thus: "The difference between a wizard and a sorcerer is comparable to that between, say, a lion and a tiger, but wizards are acutely status-conscious, and to them, it's more like the difference between a lion and a dead kitten." – Wikipedia (http://en.wikipedia.org/wiki/Wizard_(fantasy)#Names_and_terminology)
