This new edition retains the essential features of Michael West's work and brings the text up to date in various ways. It includes a vocabulary of 1,490 words with 24,000 items defined, new headwords defined for this edition, and a pronunciation system based on the International Phonetic Alphabet. Three appendices accompany the dictionary: a list of the defining vocabulary, a list of the nations and languages of the world, and a list of common abbreviations.
