Step-by-step explanation:
A thesaurus is a reference book that provides synonyms and antonyms for words. It is useful for expanding vocabulary and finding alternative words to use in writing or speech. For example, if you are writing an essay and want to find a different word for 'happy,' you can use a thesaurus to look up synonyms like 'joyful,' 'delighted,' or 'content.'
A glossary is a list of specialized or technical terms with their definitions. It is commonly found at the end of a textbook or a reference book. For instance, in a science book, a glossary may include terms like 'photosynthesis,' 'mitochondria,' or 'gravitational force,' along with their explanations.
