Ideal for all those who wish to perform more successfully in the workplace or in study, this book will tell you all you need to know about words and develop or improve your word building and vocabulary. In two parts, the first part gives advice on using active rather than passive vocabulary, how to use dictionaries and word reference books effectively as well as electronic and online reference materials, and which word to use when faced with a choice. The second gives information about word classes, word structure, and contains a detailed glossary.
