You already know that synonyms are words with almost the same meaning. A thesaurus is a tool that lists synonyms for a word, so when you are stuck on a tired, overused word, you can look it up and find fresher options.

saidwhisperedshoutedmumbled
A thesaurus entry for 'said' might list whispered, mumbled and shouted. Each one carries a slightly different feeling.
Try it together

Zara wrote 'The dog was big' three times in her story. She looked up 'big' and found large, huge, enormous, and gigantic. For a dog the size of a horse, she picked 'enormous'. For a dog just a bit bigger than normal, 'large' fits better. The right word depends on how big the dog really is.

Do not pick a word just because it sounds impressive. Check its connotation, the feeling it carries, and whether it matches how formal your writing needs to be. A true synonym can still sound wrong in your sentence. Scrawny means very thin, with bones sticking out. Skinny for a person often sounds disapproving. Slim often sounds like a compliment.

A thesaurus gives you choices, but you decide which one truly fits your sentence's meaning, feeling, and tone.
