Athesaurus is a book thats useful for finding?

A thesaurus is a book that is useful for finding synonyms, or words with the same or similar meanings. A thesaurus may also list antonyms, which are words with opposite meaning. A thesaurus is set up in a similar manner to that of a dictionary, which lists words alphabetically. However, instead of giving a definition like a dictionary, a thesaurus gives synonyms to help diversify your writing and intrigue the reader.

Hope this helps!
