Watch enough Korean dramas and you'll start to notice the same lines again and again: in hospital corridors, on rooftops, outside convenience stores at 2 a.m. That's good news for learners, because these are also lines people use in real life. Here are ten of the most common, with what they really mean and when you can use them yourself.

Most of these lines appear in casual speech (반말, banmal), because drama characters are often friends, family or couples. We give the polite version too, so you know which one to use.

1. 괜찮아? – Are you okay?

괜찮아? (Gwaenchana?) is the line that comes right after someone falls, cries or gets bad news. The polite form is 괜찮아요? (Gwaenchanayo?), and for an older person, 괜찮으세요? (Gwaenchaneuseyo?). The classic reply, often unconvincing, is 응, 괜찮아 (Eung, gwaenchana) – "Yeah, I'm fine."

2. 밥 먹었어? – Have you eaten?

밥 먹었어? (Bap meogeosseo?) literally asks whether you've had 밥 (bap) – rice, or a meal. But it's really a way of saying "How are you?" or "I care about you." A parent, an old friend or a love interest says it to show warmth. Politely: 식사하셨어요? (Siksahasyeosseoyo?) – a respectful version you can use with older people or colleagues.

3. 무슨 일 있어? – Is something wrong?

무슨 일 있어? (Museun il isseo?) means "Did something happen?" and is said when a friend looks upset or quiet. The polite form is 무슨 일 있어요? (Museun il isseoyo?). The typical deflecting answer: 아무것도 아니야 (Amugeotdo aniya) – "It's nothing."

4. 잠깐만 – Wait a second

잠깐만 (Jamkkanman) – "Just a moment" – is used to stop someone walking away or to pause a conversation. Add 요 for politeness: 잠깐만요 (Jamkkanmanyo). In real life, 잠깐만요 is also how you say "Excuse me, coming through" in a crowded subway.

5. 가지 마 – Don't go

가지 마 (Gaji ma) comes from 가다 (gada) – to go – plus -지 마 (don't). It's the line for airport goodbyes and dramatic exits. It's casual and emotional; you'd only say it to someone close. The polite version is 가지 마세요 (Gaji maseyo).

6. 보고 싶어 – I miss you

보고 싶어 (Bogo sipeo) literally means "I want to see (you)". In Korean, that's how you say "I miss you." Politely: 보고 싶어요 (Bogo sipeoyo). Grammar note: -고 싶다 means "want to", so you can also say 먹고 싶어 (meokgo sipeo) – I want to eat.

7. 됐어 – Forget it

됐어 (Dwaesseo) literally means "it's done" or "that's enough". Said sharply, it ends an argument: "Forget it" or "Never mind." It can sound cold, so be careful. The polite 됐어요 (Dwaesseoyo) is common in shops to mean "No, that's fine" when declining something, but tone still matters.

8. 왜 이래? – What's wrong with you?

왜 이래? (Wae irae?) means "Why are you acting like this?" It's said when someone behaves strangely, gets too close or overreacts. It can be playful or annoyed. Politely, you'd say 왜 이러세요? (Wae ireoseyo?), which you might hear when someone is bothering a stranger.

9. 정신 차려 – Pull yourself together

정신 차려 (Jeongsin charyeo) means "Get a grip" or "Wake up!" 정신 (jeongsin) is your mind or senses, and 차리다 (charida) means to gather. It's said to someone who has fainted, who is making bad choices, or to yourself: 정신 차리자! (Jeongsin charija!) – "Come on, focus!" It's casual and direct, so keep it for friends.

10. 수고했어 – Good work

수고했어 (Sugohaesseo) recognises someone's effort: "You worked hard" or "Thanks for your hard work." Seniors say it to juniors at the end of a day or project. In polite and formal speech it becomes 수고하셨어요 (Sugohasyeosseoyo) and 수고하셨습니다 (Sugohasyeotseumnida). You'll also hear 수고하세요 (Sugohaseyo) as a goodbye to shop staff, meaning roughly "Keep up the good work."

Which ones can you use?

Most of these work in everyday life, as long as you match the politeness level to the person. With friends your age, the casual forms are natural. With strangers, staff and anyone older, add 요 or use the honorific version. Lines like 됐어 and 왜 이래? can sound rude with the wrong tone, so learn to recognise them first and use them carefully.

Korean you can use

Next time you watch, keep a tally. You may be surprised how many of these ten lines show up in a single episode.
