Language fascinates us, and we spend a lot of time playing with it, concocting everything from puns, riddles and secret languages to wonderful prose and poetry. We also worry about it a great deal, looking up and checking words in dictionaries and usageguides, occasionally arguing about definitions. This book celebrates our capacity to play with language, as well as examining the ways we use it: in slang and jargon, swearing, speaking the unspeakable, or concealing unpleasant or inconvenient facts.
