한국어로 ""fan"을 어떻게 말 해요? How can I say "fan" in Korean? (한국어로 "fan" 어떻게 말 합니까/하나요? is more polite.) OR 한국어로 "fan"이 뭐에요? What is "fan" in Korean? My Korean friend said that in his opinion (which I believe) that if you want to know only a word, then the "뭐에요?" style sounds better. (more natural) However, for full sentences or phrases, then the "어떻게 말해요?" style is better. The answer by the way: 선풍기 = fan in Korean. ㅋㅋㅋㅋ

What Barry said is technically correct, but more colloquially, we use the ~muo ra go heyo? ending (literally what do you say for ~). How do you say "Korea" in Korean? "Korea" hanguk mallo muo rago heyo "Korea" 한국말로 뭐 라고 해요? I think you'll hear both, but probably hear the example I gave more often. We say "Hanguk" "Hanguk" ireogo heyo 한국 이라고 해요.
