What does it mean word for word?
The phrase is composed of 무슨 (what/what kind of), 일 (matter/work/event) and 이야? (is it?).
Which one should you use?
While 무슨 일이야? is a general way to ask what is wrong, 무슨 일이 있어? uses the verb for existence to shift the nuance toward asking if a specific event or problem is currently occurring.
Is there a formal and an informal way to say it?
The default form 무슨 일이야? is informal and should only be used with friends or people younger than you. To be polite, use 무슨 일이에요? when speaking to someone older than you or someone you are not close with. For formal situations, you may use 무슨 일이 있으셨나요? (What happened?), 어떤 문제가 있으신가요? (What problem do you have?) or 어떤 어려움이 있으신 건가요? (What difficulty are you experiencing?). In informal settings, you can also use 뭐가 문제야? (What is the problem?), 왜 그래? (Why are you like that?) or 무슨 일 있어? (What's up?).
How does it change in a sentence?
Changing the verb to 있어? (to exist/to have) in the phrase 무슨 일이 있어? shifts the nuance slightly toward asking if a specific event or problem is currently occurring.

museun iriya?
Did you know?
- When asking 무슨 일이야?, Koreans often tilt their head slightly or use a soft, rising intonation to signal empathy. Using a sharp or flat tone can make the question sound like a demand for an explanation rather than a caring inquiry.
- In the past, the current standard 무슨 was likely a 'hypercorrection', an accidental change made by speakers trying to follow complex grammatical rules of Middle Korean.
- While 무슨 일이야? asks what is wrong, the word 일 also means 'work' or 'job'. In Korean, the concept of a 'problem' and a 'task' often shares the same vocabulary.
