The Synonym Finder by J.I. Rodale

With a simple alphabetical arrangement this book has been expanded to include thousands of new words and expressions that have entered the language in recent years, and includes clearly labelled slang and informal words and expressions.

The Synonym Finder contains more words than any book of its kind more than 1,500,000. Sometimes, it will be consulted to find a word that will lend variety to the user's language; other times it will be consulted to remind the user of the temporarily lost word or expression that was "right on the tip of his tongue." In either case, it should be used with understanding.
