Book excerpt: If you've ever wanted a quick and easy guide to verbs and adverbs, commas and apostrophes, clauses and prepositions, then this is a must-have book for you. Easing readers gently into the study of the structure of English, Grammar: A Pocket Guide covers common questions such as: Is it "10 items or less" or "10 items or fewer"? Should I say "If I were you" or "if I was you"? Can you start a sentence with "And" or "Because"? When do you use "whom"? What is the difference between "lie" and "lay"? Is it "I feel bad" or "I feel badly"? Using examples from everyday speech and writing, this handy book "cracks the code" of off-putting grammatical jargon so that readers can enjoy learning how to think and talk about grammar. With practice exercises, a glossary, and suggestions for further reading, Grammar: A Pocket Guide is the perfect foundation for anyone wanting to improve his or her writing and communication.
