The Word 'Repulse': I hate this word. I believe 'repel' is a perfectly good word, and 'repulsion' is the noun, as well as the title of an excellent Dinosaur Jr. song. A compulsion compels you; an impulse impels you. Nobody ever says 'compulse' or 'impulse' as a verb. So why would you ever say 'repulse'? This word haunts me in my sleep, like a silver dagger dancing before my eyes. Renee looked it up and I was wrong. But I still kind of think I'm right.
