Smart as hell and funny as f***, this book explains why we can't stop swearing and what it tells us about our language and brains. 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 f***ing shame. Not only is swearing colorful, fun, and often powerfully apt, as linguist and cognitive scientist Benjamin K. Bergen shows us, the study of it can provide a new window onto how our brains process language.
