How do you formally greet someone in Korean?
I know that, Anneyeonghasseo, or Anneyeong means hello in Korean, but to formally greet someone, do you say Jon-Dae-Mal? Which one is more respectful? Thank you! :3

Question

Answer

Jondaemmal or 존댓말 is the word for respectful and formal language.
Panmal is the word for casual and intimate language.

안녕하세요 (annyeonghaseyo) is formal and respectful.  It's 존댓말 (Jon-dae-mal).
안녕 (annyeong) is casual language.  It's 반말 (panmal)
