뭐 means ‘what’ in Korean. 뭐예요 question uses ‘뭐’ as an object and native Koreans use 뭐예요 question when the subject is not identified or they really don’t know what the hell it is. You have to use 뭐예요 question especially with pronouns such as ‘this, ‘that’, ‘it’.

무엇 vs 뭐

무엇 and 뭐 are a same word. 뭐 is a shortened form of 무어 which means imperative ‘what’. 무엇 is more formal. 뭐 is more informal and native Koreans use it usually in a daily conversation.

 

Sometimes 뭐 sounds like a bit bitching because replying someone else ‘what’ can be rude in Korean. It’s similar to ‘Why’ can sound rude sometimes in English (but replying why isn’t rude much in Korean)

 

What Questions with 이다 Verb

무엇 + 이다 question means ‘What is something?’. However, it can also mean ‘which one is something’ too. Sometimes it sounds aggressive so it would be better to use 뭐예요 question for what question in Korean.
