A thesaurus is a reference book or online resource that lists synonyms (words with the same or similar meaning) and sometimes antonyms (words with opposite meanings) for a specific word.
There are many different types of thesauruses, including:
* Printed thesauruses: These are physical books that you can find in libraries and bookstores.
* Online thesauruses: Many websites offer free online thesauruses, such as Merriam-Webster's Thesaurus, Thesaurus.com, and more.
* Integrated thesauruses: Some word processors and online writing tools have integrated thesauruses that you can access directly from the text editor.
