Common forms
| Register | Hangul | Romanization | Note |
|---|---|---|---|
| casual | 잘 자 | jal ja | Between close friends, romantic partners, or younger people — the everyday night-time send-off. Very warm and natural. Often paired with 내일 봐 (naeil bwa, see you tomorrow). |
| polite | 잘 자요 | jal jayo | Polite form — safe with people slightly above your age or anyone you're not super close to. Warm but properly respectful. |
| formal (to elders) | 안녕히 주무세요 | annyeonghi jumuseyo | Honorific form used for parents, grandparents, and seniors — shows real respect. Not using this with elders and saying just 잘 자 can come across as disrespectful. |
| sweet / romantic | 꿈에서 봐 | kkume-seo bwa | Literally 'see you in my dreams' — a tender romantic way to say good night to a partner. Very popular in K-drama phone calls and late-night texts. |
How it changes by relationship
잘 자! 내일 봐!
Jal ja! Naeil bwa!
to a close friend: The most natural pairing — good night + see you tomorrow. Common in KakaoTalk messages and after late-night phone calls.
잘 자, 꿈에서 봐.
Jal ja, kkume-seo bwa.
to a romantic partner: Very sweet and common in K-drama texts and bedtime calls. 꿈에서 봐 adds a romantic touch without being over-the-top.
안녕히 주무세요.
Annyeonghi jumuseyo.
to a parent or elder: Respectful and expected in Korean households — this is the required form when saying good night to parents or any elder. Skipping it in favor of 잘 자 would feel very informal.
굿밤 ✨
gut bam
in a text (casual): 굿밤 (gut bam) is a loanword-style shorthand for 'good night' used in casual texts — sounds almost English but is widely used among younger Koreans.
Examples
잘 자, 내일 봐!
Jal ja, naeil bwa!
Good night, see you tomorrow!
안녕히 주무세요, 어머니.
Annyeonghi jumuseyo, eomeoni.
Good night, mom.
꿈에서 봐.
Kkume-seo bwa.
See you in my dreams.
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.
