This is a dictionary and thesaurus in one. Designed to be a convenient and comprehensive reference work, individual entries contain both dictionary definitions for an accurate and up-to-date guide to the language as well as thesaurus synonyms to increase vocabulary and improve style. Where thesaurus synonyms are slang, derogatory or old-fashioned uses of words, they are labelled to give guidance. This revised edition aims to be useful on many occasions, from writing a letter to solving a crossword puzzle. Also contains a new reverse dictionary supplement, which provides a guide to related words, a vocabulary builder and a puzzle-solver all in one.
