One Greeting Covers Most of the Day
Here's something that surprises most learners: Korean doesn't slice the day into greeting segments the way English does. There's no direct equivalent of "good morning," "good afternoon," or "good evening" as separate phrases.
Instead, 안녕하세요 (annyeonghaseyo) covers it all. Morning, noon, evening -- this single greeting works any time you encounter someone. It literally means "are you at peace?" and functions as the universal Korean hello.
That said, Korean does have time-specific phrases that come up in certain contexts. Here's the full picture.
Morning Greetings
| Korean | Romanization | English | Formality | |--------|-------------|---------|-----------| | 안녕하세요 | annyeonghaseyo | Hello (any time) | Polite | | 안녕 | annyeong | Hi (any time) | Casual | | 좋은 아침이에요 | joeun achimieyo | Good morning | Polite | | 좋은 아침 | joeun achim | Good morning | Casual |
좋은 아침이에요 has become more common in workplaces and group chats, though some native speakers consider it a loan-phrase influenced by English. Either way, people understand it and use it, especially in text messages. If you want to play it safe and sound naturally Korean, stick with 안녕하세요 in the morning.
Afternoon and Evening
| Korean | Romanization | English | Formality | |--------|-------------|---------|-----------| | 안녕하세요 | annyeonghaseyo | Hello | Polite | | 안녕 | annyeong | Hi | Casual | | 식사하셨어요? | siksahaseyosseoyo? | Have you eaten? | Polite | | 밥 먹었어? | bap meogeosseo? | Did you eat? | Casual |
Yes, "have you eaten?" is a genuine Korean greeting, not just a literal question about food. 식사하셨어요? (or its casual form 밥 먹었어?) shows concern for someone's wellbeing. It's especially common around mealtimes and among older generations. You don't need to give a detailed answer -- a simple 네 (ne, "yes") works fine.
There's no standard "good afternoon" or "good evening" in Korean. 안녕하세요 continues to do the heavy lifting through the entire day.
Nighttime and Goodbye
| Korean | Romanization | English | Formality | |--------|-------------|---------|-----------| | 안녕히 주무세요 | annyeonghi jumuseyo | Goodnight (sleep well) | Polite | | 잘 자 | jal ja | Goodnight (sleep well) | Casual | | 안녕히 가세요 | annyeonghi gaseyo | Goodbye (to someone leaving) | Polite | | 안녕히 계세요 | annyeonghi gyeseyo | Goodbye (to someone staying) | Polite | | 잘 가 | jal ga | Bye (to someone leaving) | Casual |
A detail K-drama fans will recognize: Korean has two different goodbyes depending on who is leaving. If you're the one staying and the other person is going, you say 안녕히 가세요. If you're the one leaving and the other person stays, you say 안녕히 계세요. If both of you are leaving, you both say 안녕히 가세요.
잘 자 (jal ja) is the go-to casual goodnight. You'll hear it constantly in K-dramas between couples and close friends, and it's one of the most common phrases in Korean texting.
The Formality Rule
The pattern across all of these greetings is consistent: the polite forms (안녕하세요, 안녕히 주무세요, 안녕히 가세요) are your defaults. Use them with anyone you don't know well, anyone older, and any professional setting.
The casual forms (안녕, 잘 자, 잘 가) are reserved for close friends, people younger than you, or people who've explicitly shifted the relationship to informal speech.
When in doubt, go polite. You will never offend someone by being too formal. You can definitely offend someone by being too casual.

These greetings are high-frequency phrases -- you'll use them every single day in Korean. That makes them ideal candidates for spaced repetition practice.
