Our intention in swearing is to shock and wound, which we do by mentioning something that should be kept secret—usually something to do with the sexual functions. But the strange thing is that when a word is well established as a swear word, it seems to lose its original meaning; that is, it loses the thing that made it into a swear word. A word becomes an oath because it means a certain thing, and, because it has become an oath, it ceases to mean that thing.
