Book excerpt: Do you know what "quatrefoil" and "impolitic" mean? What about "halcyon" or "narcolepsy"? This book is a handy, easy-to-read reference guide to the proper parlance for any situation. In this book you will find: Words You Absolutely Should Know (covert, exonerate, perimeter); Words You Should Know But Probably Don't (dour, incendiary, scintilla); Words Most People Don't Know (schlimazel, thaumaturgy, epergne); Words You Should Know to Sound Overeducated (ad infinitum, nugatory, garrulity); Words You Probably Shouldn't Know (priapic, damnatory, labia majora); and more. Whether writing an essay, studying for a test, or trying to impress friends, family, and fellow cocktail party guests with their prolixity, you will achieve magniloquence, ebullience, and flights of rhetorical brilliance.
