A thesaurus is used to d) Find the synonyms and antonyms of a word.

A thesaurus is a reference work, usually in the form of a book, that provides a group of synonyms for the words of a given language. Some books provide antonyms as well. It is a great assistant to help readers and writers to choose the word that best fits for their idea.

Unlike dictionaries, this type of publication doesn't provide definitions and don't list the words in alphabetical order.
