Sometimes people don’t understand things quickly. Maybe they get confused easily or don’t think before they speak. To describe this in a funny or creative way, people often use metaphors. A metaphor is a phrase that compares one thing to another, without using the words “like” or “as.” Instead of saying someone is slow to understand, a metaphor might say, “His brain is a broken light switch.”
These phrases can sound silly, but they are common in everyday talking. They help people explain ideas in a way that’s easy to picture.
