In the book Harry Potter and the Sorcerer’s Stone Harry is the main character who is very important to the book. He is a brave, humble, and loyal character. Harry will do anything for his friends even if it means risking his life. He is very impulsive but super kind hearted. Harry is interesting because although he has a rough life he always stays happy and I like that about him.
While metonymy replaces a concept or object entirely with a related term, synecdoche takes an element of the object and uses it to refer to the whole, and metaphor uses unlike things to draw an interesting comparison. For example, the wheels are one part of a car.
