This authoritative survey of English usage, grammar, and style offers guidance on almost any writing problem imaginable. Arranged in a single, easy-to-use A-Z list, the guide's entries include examples and quotations that show not only correct and incorrect usage but also the relative effectiveness of different expressions in context. This book confronts traditional bugbears, such as disinterested and lay vs. lie, along with a variety of new challenges, such as seeking closure and begging the question. Commonly confused words, such as impinge and infringe, are teased apart. Notes on science terms explain the difference between popular and technical uses of words like relativity and exponential growth. Rulings are given for tough calls on grammatical controversies, redundancy, and parallelism, and sensible guidance is provided on punctuation, capitalization, and other conventions of style. Both readable and well researched, this book is an eminently sensible source of advice on how to use words effectively.
