A "scratch" is a shallow, linear mark or damage on a surface. It's like when you accidentally drag your keys across your phone screen or when a cat's claw leaves a mark on your arm. It's superficial damage that usually doesn't go very deep. Scratches differ from dents, which involve an indentation. Think of a scratch as a surface-level annoyance. Often, it's more of a cosmetic problem than a serious functional one.
