My Characters Don’t Give a Damn
And why should they? Most of them don’t live in universes where damnation is a possibility. What? You didn’t think that swearing, cursing, or slang had just as much to do with world-building as how your characters speak in general?
Does everyone know the bi-lingual pun that’s in The Princess Bride? It’s the part in the film where they’re rounding up everyone in the Thieves’ Forest and the guard says to Iñigo, “Ho there!” and Iñigo replies, “Get away with your ‘HO there.'” Now, if you know that the f-word in Spanish is “joder,” pronounced HOthere, this is a pretty funny bit. If you don’t… well, you do now.
Aside from the comedy potential, William Goldman (who wrote both the novel and the screenplay) is underscoring the point that Iñigo is Spanish – which in itself underscores that The Princess Bride is set in a recognizable version of the primary world.
For our purposes, Iñigo’s example illustrates one of the prime sources for swear words: sexual acts. Anyone who pays attention is familiar with the other sources: religion, family relations, body parts, and bodily functions. Yes, sexual acts are bodily functions, at least in part. But eating, for example, doesn’t usually give rise to swear words – unless there’s something taboo involved, which gives you another clue as to the origin of a lot of profanity.
Take a moment to consider the origin of the word profanity (just in case you think religion is no big deal).
