How to Address Others in Korean

호칭 • 이름 부르기

Question today comes from Mark in Canada:

I heard Koreans do not call older people by their names. Then how do you address each other? How about in professional relationship such as colleagues or your clients?

Location Marker: ~에 vs ~에서

Question today comes from onlypenpal about the location marker, "에" vs. "에서"

질문 하나 여쭤봐도 되죠. 왜 "~에서 살고 계세요"나 "~에서 사세요"를 사용하지 않아요? 여러분들 다 " ~에 살고 계세요"나 "~에 사세요"를 사용하니까. 궁금합니다.

Answer:
@onlypenpal: I will reply in English for those whose Korean language skill is not fluent enough and wants to learn too.

"~에" is grammatically correct. "~에" is associated with verbs that do not have "movements."

Examples:
서울에 살아요. I live in Seoul
집에 있어요. I am home.

If Korean natives use "~에서" in place of "~에":

1. It's just a careless mistake.
2. This mistake is made usually by the uneducated and/or young people. So to soften up the conversation or tone of voice (such as a girl trying to sound cute or business meeting that needs to be toned down a bit), adults may make this mistake on purpose or unconsciously.

"~에서" is "from" or "at" to mean the place of occurrence. Naturally, associated verbs usually involve some kind of movement or action.

Examples:
대만에서 태어났어요. I was born in Taiwan = I am *from* Taiwan.
집에서 일해요. I work at home.
미국에서 왔어요. I am from America.

Which Tone of Speech Should I Learn First?

Question today comes from Junil Jung in Chicago, Illinois in U.S.A.

I am studying to go to Yonsei Korean Language Program in summer. I took a look at their textbooks, and they were teaching -니다 form. I read your note and understand the difference between -니다 and 아/어요 form. My question is, which one should I have learned first?

Question today comes from Johanne from Austria:

My teacher taught me -요 form. But when I talk to Korean people, they keep on correcting me and ask me to use -다/까 form. I am confused. What's the difference?
