How to Say Goodbye in Korean: 안녕히 가세요 vs 안녕히 계세요
Goodbye in Korean depends on who's leaving. If you're staying and the other person is heading out, say 안녕히 가세요 (annyeonghi gaseyo). If you're the one leaving, say 안녕히 계세요 (annyeonghi gyeseyo) to the person who stays. Casual friends swap in 잘 가 or 안녕, and phone calls end with 끊을게요 — Koreans announce the hang-up instead of just cutting off.
English has one word for goodbye. Korean has a small flowchart, and the first fork is: who's actually going anywhere?
Get this part wrong and nothing terrible happens — Koreans will understand you either way. But get it right and you sound like someone who noticed how the language actually works, not someone reciting a phrasebook line at the wrong person.
The stay/go split: 안녕히 가세요 vs 안녕히 계세요
안녕히 가세요
an-nyeong-hi ga-se-yo
Goodbye (to the person leaving)
Said BY the one staying put, TO the one walking out the door.
안녕히 계세요
an-nyeong-hi gye-se-yo
Goodbye (to the person staying)
Said BY the one leaving, TO the one who remains.
Here's the mnemonic, and it's genuinely foolproof once it clicks: the verb matches what the person you're talking to is about to do, not what you're about to do. They're leaving? You say 가세요 ("go"). They're staying? You say 계세요 ("stay"). Your own plans are irrelevant to the word choice — only the listener's next move matters.
This is why the two phrases almost never get swapped in real life even by beginners who haven't memorized the rule: you're describing the other person's immediate future, and that's usually obvious. Leave a café and the barista who's staying behind says 안녕히 가세요 to you; you, walking out, say 안녕히 계세요 back to them. Textbooks bury this logic under grammar tables when it's really just paying attention to who's moving.
Casual goodbyes: 잘 가, 안녕, 또 봐, 들어가
| Phrase | Literal meaning | When to use it |
|---|---|---|
| 잘 가 (jal ga) | "Go well" | Default casual goodbye to a friend or younger person who's leaving |
| 안녕 (an-nyeong) | "Peace" — doubles as hello | Kids, close friends, texts — context (not the word) tells you which direction it's going |
| 또 봐 (tto bwa) | "See you again" | When you'll genuinely cross paths again soon, not a polite fiction |
| 들어가 (deu-reo-ga) | "Go on in" | Doorsteps, and — oddly — the end of phone calls |
That last one trips people up. 들어가 literally means "go inside," and it started as exactly that: something you say when walking a friend to their door and sending them in safely. But it's drifted into a fixed sign-off for phone calls too, even when the other person has been home for hours. Koreans say it out of habit the way English speakers say "get home safe" to someone already at their kitchen table. Don't overthink the literal geography — it's a warmth marker now, not a location report.
Phone endings: 끊을게요
Western calls tend to just stop — a "bye," maybe a click. Korean calls almost always get a formal exit announcement: 끊을게요 (kkeu-neul-ge-yo, polite) or 끊을게 (kkeu-neul-ge, casual), literally "I'm going to cut it/hang up." Hanging up without saying it reads as abrupt, even rude, the same way walking away from someone mid-sentence would. If you only learn one phone phrase, make it this one — it single-handedly makes your calls sound less like a foreigner reading a script and more like a person who knows the call has to end somehow.
여보세요?
yeo-bo-se-yo?
Hello?
나야. 잠깐 통화 돼?
na-ya. jam-kkan tong-hwa dwae?
It's me. Got a sec to talk?
어, 말해.
eo, mal-hae.
Yeah, go ahead.
그냥… 목소리 듣고 싶어서. 이제 끊을게, 잘 자.
geu-nyang… mok-so-ri deut-go si-peo-seo. i-je kkeu-neul-ge, jal ja.
Just… wanted to hear your voice. I'll hang up now, goodnight.
어, 들어가. 잘 자.
eo, deu-reo-ga. jal ja.
Okay, go on in. Goodnight.
Long-term goodbyes: 잘 지내요, 연락할게요
안녕히 가세요 and 잘 가 are for right now — you'll likely see this person again soon, maybe tomorrow. A different vocabulary kicks in when the goodbye has weight: someone's moving abroad, a couple is separating for military service, a drama character is leaving on a one-way flight while string music swells. That's when you get the see you later family's older, heavier cousins.
- 잘 지내요 (jal ji-nae-yo) — "stay well"; the default for goodbyes with no fixed return date.
- 연락할게요 (yeol-lak-hal-ge-yo) — "I'll keep in touch"; often more hope than plan, exactly like its English equivalent.
- 보고 싶을 거야 (bo-go si-peul geo-ya) — "I'll miss you"; the line that starts the tears in every airport scene.
- 몸 조심해 (mom jo-sim-hae) — "take care of your body"; Korean affection routed through worry about health rather than the word "love."
Frequently asked questions
What's the difference between 안녕히 가세요 and 안녕히 계세요?
Both mean "goodbye" politely, but the choice depends on the listener, not you. Say 안녕히 가세요 to someone who is leaving. Say 안녕히 계세요 to someone who is staying behind while you leave. The verb tracks the other person's next move.
Is it rude to say 안녕 to someone older than you?
Yes, on its own. 안녕 is casual banmal, appropriate for close friends, people younger than you, or kids. To an elder, stranger, or anyone you'd normally speak politely with, use 안녕히 가세요/계세요 instead — 안녕 alone can come off overly familiar.
How do Koreans usually end a phone call?
With an announcement, not a silent hang-up: 끊을게요 (polite) or 끊을게 (casual), meaning "I'll hang up now." It's often paired with a warm closer like 들어가 (go on in) or 잘 자 (goodnight) depending on the time and relationship.
What do Koreans say at the airport when someone's leaving the country?
Common lines include 조심히 가 (travel safe), 잘 지내 (stay well), 연락할게 (I'll keep in touch), and 보고 싶을 거야 (I'll miss you). These are reserved for real long-term farewells, not everyday partings — using them for a quick goodbye would sound oddly dramatic.
Can I just say 바이 (bye) in Korean?
You'll hear it — 바이 is a casual English loanword used mostly in texting and among younger speakers, similar to how Koreans also text "ㅂㅂ." It's fine informally with friends but skips the stay/go logic entirely, so it won't work in any situation calling for politeness.
