What would you use a Thesaurus for?

A thesaurus is a reference book or website that lists words grouped together according to similarity of meaning. It is used to find synonyms, or words with the same or similar meanings, and antonyms, or words with opposite meanings. A thesaurus can be used to improve vocabulary, find the right word for a specific context, or come up with new ideas for writing. It can also be a fun and educational tool to browse and explore different words and their meanings.
