A sneaky--charming, consistently engrossing--introduction to linguistics. --New York Times Book Review Everyone swears. Only the rare individual can avoid ever letting slip an expletive. And yet, we ban the words from television and insist that polite people excise them from their vocabularies. That's a fucking shame.

Bergen shows us, the study of it can provide a new window onto how our brains process language. How can patients left otherwise speechless after a stroke still shout out Goddamn ? Why did Pop Francis say fuck in the middle of a speech? When did a cock cease to be a rooster? Why is crap vulgar when poo is just childish? And what are we doing when we give someone the bird? What the F? Let me effing tell you.
