Usage note

There is no single Korean phrase that maps exactly to 'good night' as a farewell — 잘 자 literally means 'sleep well,' so it's used when someone is actually heading to bed, not as a general evening goodbye. If you're leaving a gathering in the evening but people aren't going to sleep yet, 잘 가요 (take care, go well) or 안녕히 가세요 is more appropriate. The honorific form 안녕히 주무세요 is not optional with elders — Korean households have a clear etiquette around this bedtime expression that younger speakers are expected to follow.
