You’ll never again confuse affect and effect!

Have you ever been fazed by the spelling of phased, or fretted over the difference between anxiety and angst, stationery and stationary? If so, you are not alone: the English language is a minefield, full of words that look and sound alike but mean different things in different places.
 
Who’s Whose? is an entertaining and essential A to Z guide to the most commonly confused words in English today, with real examples of good and bad usage to make differences crystal clear. In addition to documenting these verbal confusions, it offers a sympathetic guide to the seriousness of each gaffe (the Embarassment rating), an explanation of why it happens, and some handy hints on how to avoid it in future. With Who’s Whose in your corner, you’ll never again mistake a principle for a principal.
