"Rollicking, salty, learned, and intensely informative, John McWhorter's Nine Nasty Words is a grand tour through the history of the profanities we (sometimes) abhor and (sometimes) revel in (and sometimes both), peppered with cameos by everyone from Geoffrey Chaucer and Cole Porter to Tallulah Bankhead and the too-little-known singer-songwriter Lucille Bogan, still making people blush 70-odd years after her death, God bless her. I laughed frequently and learned plenty." (Benjamin Dreyer, New York Times best-selling author of Dreyer's English)

"Nine Nasty Words is a deeply intelligent celebration of language that teaches us how to see English in high definition and love it as it really is, right now and in its myriad incarnations to come." (The New York Times)

"Shakespeare’s Caliban spoke for the human race when he said 'You taught me language, and my profit on’t is, I know how to curse.' Taboo language combines our touchiest social emotions with the poetic and metaphorical powers of language, and no one can explain these more clearly and compellingly than John McWhorter." (Steven Pinker, Johnstone Professor of Psychology, Harvard University; author of The Stuff of Thought: Language as a Window Into Human Nature)
