An abridged edition of the world's bestselling original thesaurus. This completely revised and updated edition contains over 230,000 words, nearly three thousand of which are newly added. The revolutionary achievement of Dr Roget was his development of a brand new principle: the grouping of words according to ideas. If the user cannot find something in a reference book, it is often because of the restriction of searching alphabetically by 'known' headwords. Dr Roget's thesaurus reversed the access to allow the user to find a word from another word, a concept or an idea. This ultimate reference tool – the best–selling thesaurus ever in all its editions – contains over 230,000 words and phrases, nearly 3000 of which are new to this edition, grouped into 1072 numbered categories. Within each category you'll find all the parts of speech, frequent cross–references, commonly used words singled out in boldface, and much more. If you're a writer who needs help organising a thought or mastering the nuance of expression, the International Thesaurus remains the first source to turn to. Read Less
