Common Mistakes to Avoid

  • Using 안녕 with someone older or a stranger — always default to 안녕하세요 unless you're sure it's appropriate to be casual
  • Thinking 안녕하세요 is too formal for everyday use — it's actually the standard greeting for most situations in Korea
  • Using 안녕 as a formal goodbye — the polite goodbye forms are 안녕히 가세요 (to someone leaving) and 안녕히 계세요 (to someone staying)
  • Forgetting that 안녕 works as both hello AND goodbye in casual Korean
