신경 쓰지 마세요 (singyeong sseuji maseyo) — "Don't Go to Any Trouble for Me": The Phrase Koreans Use Most Often to Decline
신경 쓰지 마세요
Let’s say you’ve been invited to a Korean friend’s home for the first time. The moment you sit down, your host starts shuttling between the kitchen and the living room — slicing fruit, brewing coffee, fetching one more floor cushion. As the guest, you feel more and more awkward just sitting there. This is exactly the moment when a Korean is most likely to say 신경 쓰지 마세요 (singyeong sseuji maseyo). 신경 쓰지 마세요 means “you don’t have to spend your mind on that” — in other words, “don’t go to any trouble or worry on my account.” In English it lands somewhere between Don’t worry about it, Don’t go to any trouble, and Never mind.
Take the phrase apart and the picture comes into focus. 신경 (singyeong) comes from the hanja 神經 and refers to the nerves running through your body. Attached to it is 쓰다 (sseuda), meaning “to use up, to spend.” So 신경을 쓰다 (singyeong-eul sseuda) literally means to wear your nerves down — that is, to pour mental and emotional energy into something. Which makes 신경 쓰지 마세요 a vividly literal way of declining: “Please don’t spend your nerves on me.”
It’s used in two main ways. The first is to decline someone’s effort. When someone is preparing something for you or fussing over you, this gently stops them: “I’m fine, you really don’t have to.” The second is to lighten someone’s worry. When the other person is stewing over a small mistake or a minor issue, it lets them off the hook: “You don’t need to hold on to that.” The first is a refusal of care; the second is a release from a burden.
That said, just because it’s in polite speech doesn’t mean it fits anywhere. -지 마세요 (-ji maseyo) is polite only in form — at its core it’s a prohibition. It’s the bare command “하지 마세요 (haji maseyo, don’t do it)” dressed in polite clothing. So if you toss this phrase at a senior who is showing concern for you, it can come across not as gratitude but as cutting off their care. This is where learners slip most often, and we’ll come back to it below.
See It in a Real Conversation
Situation: It’s Emily’s moving day. Boxes are piled up like a mountain in her new living room, and Jun-kyung has come over to help haul things in.
Jun-kyung: 야, 이 박스 어디다 놔? 주방이라고 쓰여 있는데. Hey, where should I put this box? It says “kitchen” on it.
Emily: 그냥 아무 데나 놔. 신경 쓰지 마, 어차피 오늘 밤에 내가 다 다시 풀 거야. Just put it anywhere. Don’t worry about it — I’m going to unpack everything again tonight anyway.
Jun-kyung: 아까 1층에서 집주인 아저씨 마주쳤는데, 사다리차 소리 되게 시끄럽다고 하시더라. I ran into the landlord downstairs — he said the ladder truck was really loud.
Emily: 아, 나도 아침에 죄송하다고 했거든? 근데 “신경 쓰지 마세요, 다들 이사할 때 한 번씩 그래요” 하시더라고. Oh, I apologized this morning too. But he said, “Don’t worry about it, everyone’s like that on moving day.”
Jun-kyung: 다행이네. 근데 너 아침부터 물만 마셨지? 나 밑에 편의점 갔다 올게. That’s a relief. Hey, you’ve only had water since this morning, right? I’ll run down to the convenience store.
Emily: 아니야, 진짜 신경 쓰지 마. 너 짐 옮겨 준 것만으로도 이미 미안해 죽겠어. No, seriously, don’t bother. I already feel bad enough just having you carry boxes.
This Sounds Off
✗ (When your manager asks, “자네 이번 주 야근 많았지? 몸은 괜찮나?” — You’ve been working late a lot this week, haven’t you? Are you holding up okay?) 부장님, 신경 쓰지 마세요. 제가 알아서 하겠습니다. ✓ 부장님, 신경 써 주셔서 감사합니다. 이번 주만 지나면 괜찮습니다. (Sir, thank you for your concern. Once this week is over I’ll be fine.) → No matter how many polite endings you attach, -지 마세요 is a prohibition. Say it to a senior who’s worried about you and it reads as “please stop” — leaving an impression of a line drawn rather than thanks given. A senior’s concern is safer received with gratitude than blocked.
✗ (After a friend has poured out a long story about their parent’s health) 너무 신경 쓰지 마세요. ✓ 많이 걱정되시겠어요. 검사 결과 나오면 꼭 알려 주세요. (That must be so worrying. Please let me know when the test results come in.) → The heavier the other person’s heart, the more this phrase shuts them down instead of comforting them — because it sounds like “stop thinking about that.” 신경 쓰지 마세요 belongs strictly to light matters, things the other person really doesn’t need to spend their mind on.
Example Sentences by Situation
① When a server spills a little water and gets flustered
A server sets down your water glass, splashes some on the table, and keeps apologizing. Here’s the one line that lets you, as the customer, make it no big deal.
괜찮아요, 신경 쓰지 마세요. 안 젖었어요. gwaenchanayo, singyeong sseuji maseyo. an jeojeosseoyo. (괜찮아요, 신경 쓰지 마세요. 안 젖었어요. — It’s fine, don’t worry about it. Nothing got wet.)
② When someone you’re visiting in the hospital keeps trying to get up
You’ve gone to see someone who’s been admitted, and the patient keeps trying to sit up to look after you. It also works the other way around — the patient saying it to the visitor.
저는 신경 쓰지 마시고 편하게 앉아 계세요. jeoneun singyeong sseuji masigo pyeonhage anja gyeseyo. (저는 신경 쓰지 마시고 편하게 앉아 계세요. — Don’t mind me, just sit comfortably.)
Connecting it with -지 마시고 (-ji masigo) noticeably softens the edge of the command. The sentence doesn’t stop there — it flows on into the invitation “편하게 앉아 계세요 (pyeonhage anja gyeseyo, please stay seated and relax).”
③ When there’s noise at home during a video call
You’re in a meeting while working from home, and a child crying or construction noise leaks in from the next room. This is the line that lets you apologize and get the meeting rolling again.
죄송합니다, 신경 쓰지 마시고 계속 진행해 주세요. joesonghamnida, singyeong sseuji masigo gyesok jinhaenghae juseyo. (죄송합니다, 신경 쓰지 마시고 계속 진행해 주세요. — Sorry, please ignore that and go ahead.)
Polite and Casual Forms, and Similar Expressions
| Expression | Tone & Force | Where It Fits |
|---|---|---|
| 신경 쓰지 마세요 (singyeong sseuji maseyo) | Polite, but a command in form | Shop staff, neighbors, business contacts — mostly equals, juniors, or strangers. Careful with seniors |
| 신경 안 쓰셔도 돼요 (singyeong an sseusyeodo dwaeyo) | The softest option | Safe even with seniors. It’s framed as “permission,” not prohibition, so it has no edge |
| 신경 쓰지 마 (singyeong sseuji ma) | Casual and close | Friends, younger siblings, partners. Never with someone older or above you |
| 마음 쓰지 마세요 (maeum sseuji maseyo) | Warm and formal | For moments where real care has been given: gifts, condolences, hospital visits |
| 괜찮아요 (gwaenchanayo) | Neutral, the widest net | Works anywhere. But it stops at “no problem” — it can’t reach “please stop” |
| 됐어요 (dwaesseoyo) | Curt and cold | Reads as a refusal rather than a polite decline. Even a slightly sharp tone makes it rude |
The key one is 신경 안 쓰셔도 돼요 (singyeong an sseusyeodo dwaeyo). Same meaning, but the frame of the sentence shifts from “don’t do it (prohibition)” to “you don’t have to (permission),” which leaves the choice in the other person’s hands. If you’re hesitating over what to say in front of someone senior, pick this one and you’ll almost never go wrong.
Cultural Background — Not Wanting to Be a Burden
Korean has a phrase that comes up constantly: 폐를 끼치다 (pye-reul kkichida, to inconvenience someone). It names the discomfort of making someone else burn their time and effort on you — and 신경 쓰지 마세요 is that feeling hardened into a sentence. “Don’t wear your nerves down on my account” — it’s a form of consideration that recognizes the cost the other person is paying for you and hands it back.
Which is why, in real life, this phrase is usually not accepted the first time. The guest says “신경 쓰지 마세요” and the host keeps slicing fruit anyway; the host says “신경 쓰지 마세요” and the guest ends up helping with the dishes anyway. Only after the declining and insisting have gone back and forth two or three times does everyone settle. That back-and-forth is the greeting — dropping your hands at the first word isn’t the polite move. This is what foreign learners most often miss when they’re invited to a Korean home.
In K-dramas, too, this line usually shows up in the gap between what someone says and what they actually feel. The character who cares enormously but turns away saying “신경 쓰지 마세요”; the character who feels hurt when the other person takes it at face value and genuinely stops caring — Korean melodrama has been replaying this scene for decades. Taken literally it’s a polite decline, but depending on the situation it can flip into the exact opposite: “please, care a little.”
One more thing. The similar-looking 신경 쓰여요 (singyeong sseuyeoyo) means something different. This one means your mind keeps drifting there whether you want it to or not. You’d use it like “아까 그 말이 계속 신경 쓰여요 (What you said earlier keeps bugging me).” If 신경 쓰다 (singyeong sseuda) is active, 신경 쓰이다 (singyeong sseuida) is passive. One syllable separates “I put my mind into it” from “my mind keeps getting pulled there.”
Today’s Quiz
Your manager asks: “자네 이번 주 야근 많았지? 몸은 좀 괜찮나?” (You’ve been working late a lot this week, haven’t you? Are you holding up okay?) Which of the following is the most natural reply?
- 부장님, 신경 쓰지 마세요.
- 신경 쓰지 마.
- 신경 써 주셔서 감사합니다. 이번 주만 지나면 괜찮습니다.
- 됐어요, 저는 신경 쓰지 마세요.
Answer: 3
Number 1 is polite in form, but it’s ultimately the prohibition “please stop” — it comes across as cutting off a senior who’s worried about you. Number 2 is casual speech, so it’s out of the question. Number 4 piles on 됐어요 (dwaesseoyo), adding the chill of outright refusal. A senior’s concern is not something to block but something to receive with thanks. If you really do want to decline, “신경 안 쓰셔도 됩니다 (singyeong an sseusyeodo doemnida)” is as far as you can safely go.
