What does, good morning,good afternoon and good evening in Korean?? ^____^V

Question

Answer

You can say "좋은 아침" which means "good morning" :D

Answer

안녕하세요 - Can mean Good Morning, Good Afternoon, Good Evening. But literally it means "Are you at peace."

That's why often you will hear Koreans say it as a question for example. 
A. 안녕하세요?  (Are you at peace?)
B. 네, 안녕하세요~?. (Yes, How about you?)

좋은 아침 = Good morning. 
좋다 - to  be good
아참 - morning

You could also use Konglish and say "굿모닝" like this as well. : )

Your best bet is just to use 안녕하세요~  though. ^_^

Answer

All at once " 안녕하세요 " :)
