들어오세요 (deureooseyo) — The One Phrase That Calls the Guest at Your Door Inside
들어오세요
들어오세요 (deureooseyo) is a polite way of asking someone who is outside a door — or outside in general — to “please come in.” When someone knocks on your office door, when a guest is standing at the entryway for your housewarming, when the person who’s been waiting their turn in a clinic lobby is called into the exam room — this is a greeting that passes through doorways countless times a day in Korea.
The phrase is the verb 들어오다 (deureooda) with -세요 (-seyo) attached, the polite ending used for commands and invitations. It’s an imperative in form, but in Korean -세요 is gentler than ~하십시오 (~hasipsio) and far more courteous than plain ~해 (~hae), so it comes across as an invitation rather than an instruction. That’s why 들어오세요 doesn’t sound like the blunt 들어와라 (deureowara), “get in here.” It sounds like “you’re welcome to come in, please” — a phrase that lowers the threshold for you.
There’s one thing to watch out for. This expression has the speaker’s own position built into it. 들어오다 is a compound of 들다 (deulda, to head inward) and 오다 (oda, to move toward the speaker), which means you can only use it when you are already inside. If I’m in the room and you’re outside, it’s 들어오세요; if I’m outside and you’re the one who has to go in, it’s 들어가세요 (deureogaseyo). Both get translated as “enter” in English, but in Korean they belong in completely different situations. This is exactly the spot where learners slip up most often.
Let’s see it in a real conversation
Scene: Jun-kyung has just moved into a new place. On the evening of the housewarming, Emily is the first to arrive, carrying a cake box.
Jun-kyung: 어, 왔어? 뭐 하고 서 있어, 얼른 들어와. 신발은 아무 데나 벗어. Oh, you’re here? What are you standing there for—come on in. Just leave your shoes anywhere.
Emily: 잠깐만, 케이크 상자 좀… 됐다. 와, 집 진짜 넓다. Hang on, let me put the cake box down… okay. Wow, this place is huge.
Jun-kyung: (초인종 소리) 네— 문 열려 있어요, 들어오세요! (doorbell) Yes—the door’s open, please come in!
Emily: 야, 나한텐 “들어와”고 저분한텐 “들어오세요”야? Hey, so it’s “deureowa” for me and “deureooseyo” for him?
Jun-kyung: 당연하지. 아랫집 아저씨야. 너한테 “들어오세요” 했으면 우리 십 년 우정 끝난 거고. Obviously. That’s the guy from downstairs. If I’d said “deureooseyo” to you, our ten-year friendship would be over.
Emily: 하긴. 근데 아저씨한테 할 때 목소리 왜 그렇게 상냥해? Fair enough. But why does your voice get so sweet when you say it to him?
The same meaning splits into 들어와 (deureowa) and 들어오세요 (deureooseyo) depending on who you’re speaking to. If you deliberately use 들어오세요 with a close friend, it either reads as a joke or as a genuine signal that you’re putting distance between you. That’s what makes Jun-kyung’s last line funny.
These sound off
✗ (Parting ways late at night) 오늘 고마웠어요. 조심히 들어오세요 (deureooseyo). ✓ 오늘 고마웠어요. 조심히 들어가세요 (deureogaseyo). Thanks for today. Get home safe. → You aren’t at the place the other person is heading to (their home). When someone is heading into a space where you aren’t, the word is 들어가세요. The standard farewell has settled into the fixed phrase 안녕히 들어가세요 (annyeonghi deureogaseyo), so if you say “들어오세요” here, the other person pauses for a beat and wonders, “Wait, are they telling me to come over to their place?”
✗ (To a customer standing at the café door) 손님, 들어오세요 (deureooseyo). ✓ 손님, 어서 오세요 (eoseo oseyo). Welcome! → The grammar is fine, but the setting is wrong. The set greeting for welcoming a customer into a shop is 어서 오세요. Using 들어오세요 in this spot sounds less like a welcome and more like a direction — “please move inside” — which comes off as oddly businesslike from the customer’s side.
Example sentences by situation
1. When you hear a knock on your office door
You’re working inside and there’s a knock. Instead of getting up to open the door, you answer from where you’re sitting. You’ll hear this several times a day in a Korean office.
네, 들어오세요 (ne, deureooseyo). Yes, come in.
2. When a guest is standing at your front door
The person you invited over has arrived. You say this as you open the door, and adding 어서 (eoseo) in front makes it much warmer. Following it up with a bit of modesty is the Korean way of greeting.
먼 길 오시느라 고생하셨어요. 어서 들어오세요 (eoseo deureooseyo). 차린 건 없지만요. Thanks for coming all this way. Please, come on in. I haven’t got much prepared, though.
3. When calling the next person in from a waiting room
You’ll hear this anywhere people wait outside and get called in — clinics, hair salons, counseling offices. It comes right after the name or number is called.
김민수 님, 3번 진료실로 들어오세요 (deureooseyo). Kim Min-su, please come into exam room 3.
Polite and casual forms, and related expressions
| Expression | Tone & strength | Where it’s used |
|---|---|---|
| 들어오세요 (deureooseyo) | Polite and gentle | Guests, colleagues, people you’ve just met. The safest default |
| 들어와 (deureowa) | Casual and friendly | Friends, younger siblings, family. Never to someone senior to you |
| 들어와요 (deureowayo) | Polite but less formal | Close seniors and juniors, neighbors close to you in age |
| 들어오시죠 (deureoosijyo) | Formal, slightly stiff | Meeting rooms, job interviews, business settings |
| 어서 오세요 (eoseo oseyo) | A greeting of welcome | Greeting a customer in a shop |
| 들어가세요 (deureogaseyo) | The exact opposite direction | Saying goodbye, seeing someone off |
The two most important rows in the table are the top one and the bottom one. If you’ve memorized 들어오세요, you absolutely have to memorize 들어가세요 as a set with it. Korean is a language that layers the speaker’s position onto its motion verbs, so picking the wrong one between 오다 (oda) and 가다 (gada) throws the whole sentence off.
Cultural background — what happens at the threshold
In Korea, the entryway isn’t just a passage. It’s where you take off your shoes, and it’s the boundary that divides outside from inside. That makes 들어오세요 both a permission — “you may pass through this door” — and a gesture of the heart: “I’m letting you into my space.” The invited guest hesitating for a moment at the entryway, the host repeating “어서 들어오세요” a couple of times, modest phrases like 누추하지만 (nuchuhajiman), “it’s a humble place, but…”, or 차린 건 없지만 (charin geon eopjiman), “I haven’t prepared much, but…”, slipping in between — this brief back-and-forth is the basic scene of Korean hospitality.
Take the expression apart and you can see the culture in it. 들다 (deulda) means to head inward, and 오다 (oda) means to move toward the speaker. Put together, 들어오다 (deureooda) ultimately means “to come toward the inside where I am,” so this one phrase always carries the assumption that the speaker already occupies that space. Conversely, 들어가세요 (deureogaseyo), used when seeing someone off, is a wish that they make it safely back to their own place. That’s also why Koreans often say 들어가세요 rather than 잘 가 (jal ga), “bye,” when parting. It’s a greeting built on the premise that the destination isn’t the road but a home — that there’s a safe inside for you to return to.
Korean dramas set in the alleyways of the 1980s show this scene especially often. The front gate is always open, a neighbor walks right into the yard carrying a dish of side dishes, and the host pokes their head out of the kitchen to shout for them to come inside. Apartment doors today are shut far more firmly than they were back then, but the words that come out the moment the door opens are still the same.
Today’s quiz
It’s eleven at night, and Jun-kyung’s housewarming has wrapped up. Emily is putting her shoes on and heading out the front door, and Jun-kyung sees her off with a parting greeting. Which is the right thing for Jun-kyung to say?
- 오늘 고마웠어. 조심히 들어오세요.
- 오늘 고마웠어. 조심히 들어가세요.
- 오늘 고마웠어. 어서 들어오세요.
The answer is number 2. The place Emily is headed is her own home, and Jun-kyung isn’t there. When the other person is moving into a space where the speaker isn’t, you use 들어가세요 (deureogaseyo). Options 1 and 3 end up meaning “come back inside my place,” which makes no sense coming from someone who has just started walking their guest out. For the record, since these two are friends, the most natural thing in real life would be something like 조심히 들어가 (josimhi deureoga).
