Welcome to English in a Minute, where we teach you all about idioms in American English.

Have you ever heard someone say: what's up? what's up? what's up? what's up?

Let's take a look at this conversation:

Man: Hey,what's up?

Women: What's up? How are you?

Man: I'm doing fine, thanks.

This phrase is a casual expression and is normally used when you're talking to friends, family, or colleagues.
You would not want to use it in a formal or business situation.

"What's up?" is a greeting. It's a different way of saying "What's happening?"

When you ask someone "What's up?" in a conversation, it's another way to say: hello, ask how things are going, how the person is feeling. It's a common greeting used by just about everybody in America!

And that's English in a Minute.
