Casual: friends and people younger than you
뭐야 (mwoya) means "What is it?" or "What?" in casual Korean. As a reaction, it works like "What the...?" or "What's going on?" when something is surprising or annoying.
Where it comes from
뭐 means "what" (short for 무엇), and 야 is a casual ending meaning "is". Together they literally mean "What is (it)?"
How to use 뭐야
Use 뭐야? as a real question, as in 이게 뭐야? (What is this?), or as a reaction to something unexpected.
The tone matters a lot. Said softly it is curious, but said sharply to a person it can sound annoyed or confrontational, like "What's your problem?"
It is casual, so use the polite form 뭐예요? with people you don't know well or who are older than you.
