Mrs. Malaprop is a famous figure of fun in Richard Brinsley Sheridan's classic eighteenth-century comedy, The Rivals, because she always uses words incorrectly. Students who always use words incorrectly are likely to get bad grades—and that isn't very funny. Here's a book that will set them straight, offer fast, on-the-spot advice, develop their word power, and improve their grades. It will help many others too, including business people who need to write clear and succinct letters, memos, and reports, and ESL students who need to improve their command of English. Anyone who needs to think twice about the difference between adapt and adopt or immunity and impunity will profit from this easy-to-understand book. It defines and discusses approximately 1,500 tricky and often-confused words and phrases, and shows how to use them all correctly.
