Is there anyone Korean here?
this sentence can be translated as many form
1.여기 누구 한국인(=한국사람) 있어요?
2.여기 한국인(=한국사람) 있어요?
actually these two sentence has same meaning
but incase of '1' sentence emphasis anyone
each of sentence can get a litte difference when you change the end word of the sentence
but it is hard grammar so you can ignore this at now
wish u good luck
