We tend to think of swear words as one entity, but they actually serve several distinct functions. Steven Pinker, in The Stuff of Thought, lists five different ways we can swear: “descriptively (Let’s fuck), idiomatically (It’s fucked up), abusively (Fuck you…!), emphatically (This is fucking amazing), and cathartically (Fuck!!!).” None of these functions require swearwords. In Bikol (a language of the Philippines), there’s a special anger vocabulary – many words have alternative words that refer to just the same thing but also mean you’re angry. In Luganda (an African language), you can make a word insulting just by changing its noun class prefix – from a class for persons to a class for certain kinds of objects, for instance. In Japanese, you can insult someone badly just by using an inappropriate form of ‘you’.
