Here's why:
* Thesaurus is a separate reference tool: A thesaurus is a dictionary of synonyms and antonyms, meant to expand vocabulary and provide alternative words.
* Books have their own dictionaries: Some books, especially academic or technical ones, may have a glossary of terms specific to the book's content. This is not a thesaurus but a dictionary for understanding the book's unique vocabulary.
Where to find a thesaurus:
* Online: Many free online thesauruses are available, such as Merriam-Webster, Thesaurus.com, and Dictionary.com.
* Printed: Physical thesauruses can be found in bookstores or libraries.
