It's a tricky one because it can have a few different meanings depending on the context:
* To crush: This is the meaning we're looking for - to press something with great force, causing it to break or become flat. (Example: "The car crushed the tin can.")
* To have a crush on: This is a completely different meaning, referring to romantic infatuation. (Example: "She has a crush on her classmate.")
So, "crush" can be both a verb meaning to crush something physically, and a noun meaning a strong feeling of romantic attraction.
