The American Heritage Book of English Usage

This book is designed to inform you about current problems in English usage so you can make intelligent decisions when communicating. When confronted with a choice about a usage, you may ask yourself a number of questions: Has this usage been criticized for some reason in the past? If so, are these criticisms substantial? What are the linguistic and social issues involved? Have people frequently applied this usage in the past, and for how long? What do well-respected writers think of the usage today? You will find answers to these and many other questions in this book.
