This series is designed to help anyone who needs to "get to grips" with the rules and conventions of written English, whether for study, business or general self-improvement and confidence. Each volume offers a guide to a particular aspect of English usage, this book looking at vocabulary, while together the four titles form a comprehensive source of learning and reference. The material has been arranged in a way that allows systematic, progressive study and/or "dip-in" referral at need.
