Updated and expanded from one of the most popular grammar sites on the web, this book provides a modern guide to English usage for the 21st century. With topics arranged alphabetically and written in an enjoyable and readable tone, The English A User’s Guide will help students and writers understand the nature of the language, explaining the 'why' of the rules as well as what constitutes good grammar and style. Going beyond the prescriptive wrong /right examples, Jack Lynch includes examples of weak/strong, good/better, disputed/preferred, and informal/formal usage.
As far are grammar and composition books go, this is pretty useful. It reads quickly and is arraigned alphabetically so things are easily found to reference. Worth the money if you are a blogger or academic writer.
