시월드 (siwoldeu) — The Country You Enter Without a Passport When You Get Married
시월드 (siwoldeu)
시월드 (siwoldeu) likens the entire web of relationships a married woman takes on with her husband’s family to a single ‘world.’ Her husband’s mother and father, his siblings and relatives, and everything tangled up with them — holidays, ancestral rites, terms of address, seating order, the constant reading of the room in how you speak — all get bundled together under this one name. It’s like a country you enter without a passport or a visa the moment you step out of the wedding hall, and Koreans mark that strangeness by reaching past the plain word 시댁 (sidaek), ‘the in-laws’ house,’ for the exaggeration of 월드 (woldeu), ‘world.’
The places this word comes out are fairly predictable. The meat counter at the supermarket right before a holiday weekend, the lunch hour at work, a KakaoTalk chat with a friend, an anonymous online community. They all have one thing in common: the people being talked about aren’t there. 시월드 isn’t a neutral name for the husband’s family — it’s a way of dressing the exhaustion that comes out of that relationship in the costume of a joke.
The nuance breaks into three parts. First, it’s half a joke and half a sigh. Someone furious to the top of her head doesn’t say 시월드; she just talks about her mother-in-law. 시월드 is for when there’s still enough room left to say it with a smile — or when smiling is the only way to get through it. Second, the speaker is almost always the daughter-in-law. If a husband called his own parents 시월드, the sentence simply wouldn’t work. Third, you never use it in front of the people it refers to. Break even one of these three and the sentence turns awkward, or rude.
Seeing It in a Real Conversation
Setting: two days before the Seollal holiday, evening, at the meat counter of a neighborhood supermarket. Emily is putting her third pack of galbi into her cart.
Jun-kyung: 어? 에밀리 아니야? 갈비를 무슨 세 팩이나 사? Huh? Emily, is that you? Three packs of galbi?
Emily: 아 준경 씨. 나 내일 새벽부터 시월드 출근이잖아. Oh, Jun-kyung. I clock in at the in-law world at dawn tomorrow.
Jun-kyung: 아이고. 올해도 큰집에 다 모여? Oof. Everyone gathering at the eldest uncle’s place again this year?
Emily: 응. 작년엔 전만 부치다 끝났는데, 올해는 갈비찜까지 나한테 넘어왔어. Yeah. Last year I just fried jeon all day, but this year the braised galbi landed on me too.
Jun-kyung: 야, 그건 좀 심하다. 우리 형수도 맨날 그래. 시월드엔 퇴근이 없다고. Hey, that’s too much. My sister-in-law always says the same thing — the in-law world has no clock-out.
Emily: 그러니까. 연휴 끝나면 나 이틀은 앓아누울 듯. Right? After the holiday I’ll be flat on my back for two days.
This Sounds Off
✗ (on the phone with your mother-in-law) 어머님, 저 이번 주말에 시월드 갈게요. ✓ (on the phone with your mother-in-law) 어머님, 저 이번 주말에 찾아뵐게요. → 시월드 is something you say behind their backs, carrying the fatigue that family causes you. Use it directly to one of them and you’re essentially announcing, ‘Your home is a country of labor to me.’ To their faces, use 시댁 (sidaek) or simply 댁 (daek), ‘your place.’
✗ (a husband talking about his wife’s parents’ house) 나도 명절마다 시월드 가느라 힘들어. ✓ (a husband talking about his wife’s parents’ house) 나도 명절마다 처가 (cheoga) 가느라 힘들어. → The prefix 시(媤) attaches only to relatives on the husband’s side. For a man, a 시월드 doesn’t exist at all. If you really want a matching pair, there’s the jokey 처월드 (cheowoldeu), but it’s used far less often.
Example Sentences by Situation
1. A friend three years into marriage talking about her holiday plans this year (casual speech, between friends)
이번 설엔 시월드 안 가고 우리끼리 제주도 가기로 했어. (ibeon seoren siwoldeu an gago urikkiri jejudo gagiro haesseo.) This Seollal we decided to skip the in-law world and go to Jeju, just us.
It means the couple has agreed not to go to the in-laws’ for the holiday. In Korea that decision is a bigger event than it sounds, so a line tossed off this lightly usually has months of persuading and careful timing underneath it. The friend hearing it typically answers with, ‘Wow, how did you pull that off?’
2. A KakaoTalk message to a friend on the day a new group chat appeared (casual speech, text)
시월드 단톡방에 초대됐어. 이제 도망갈 데도 없다. (siwoldeu dantokbange chodaedwaesseo. ije domanggal dedo eopda.) I got added to the in-law world group chat. Now there’s nowhere left to run.
It means she’s been invited into a group chat containing the entire in-law family. The feeling that the buffer zone she maintained through physical distance has vanished comes out as 도망갈 데도 없다 (domanggal dedo eopda), ‘there’s nowhere left to run.’ It’s also a good illustration of why it’s a 월드 (woldeu), a ‘world,’ in the first place — once you’re in, there’s no logging out.
3. A post title on an anonymous community board (polite speech, to no one in particular)
시월드 스트레스, 다들 어떻게 푸세요? (siwoldeu seuteureseu, dadeul eotteoke puseyo?) In-law world stress — how does everyone deal with it?
Move the same line from casual speech to polite speech and the word itself doesn’t change. What matters is that a post like this shows up on an anonymous board at all — which tells you it’s hard to say under your real name.
Politeness Levels and Similar Expressions
시월드 is a noun, so it has no separate polite and casual forms. What changes isn’t the word but the ending at the end of the sentence — and, above all, whether this is a place where you can bring it up at all. Wrap it in the politest speech you like and you still can’t say it in front of your mother-in-law.
| Expression | Temperature / intensity | Where it’s used |
|---|---|---|
| 시월드 (siwoldeu) | Half joke, half sigh | With peers, friends, anonymous communities. Off-limits in front of the family itself |
| 시댁 (sidaek) | Neutral, respectful | Anywhere. Safe on wedding invitations, in formal conversation, and to their faces |
| 시집살이 (sijipsari) | Heavy, old-fashioned hardship | When the speaker is of an older generation, or telling a life story. No humor in it |
| 처월드 (cheowoldeu) | A joke that mimics 시월드 | When a husband talks about his wife’s family. Rarely used |
It’s especially useful to know the distance from 시집살이 (sijipsari). 시집살이 is an old word for the hard life a daughter-in-law lives in her husband’s family home — it carries the weight of a black-and-white photograph. 시월드 takes that weight and twists it lighter, in the idiom of the internet generation. They point at the same reality, but one is a word for enduring it and the other is a word for laughing it off.
Cultural Background — Seven in the Morning on a Holiday
The word-building is simple. Take 시(媤), the prefix Korean attaches to relatives on the husband’s side — 시어머니 (sieomeoni, mother-in-law), 시아버지 (siabeoji, father-in-law), 시누이 (sinui, husband’s sister), 시동생 (sidongsaeng, husband’s younger sibling), 시댁 (sidaek, the in-laws’ house) — and tack the English ‘world’ straight onto it. It was coined in an era when the ○○월드 pun, borrowed from amusement park names, was spreading online, so a wry humor was baked into the sound of it from the start. A name meant for a world built to be fun, stuck onto a place that is not fun at all.
The moment this word really lands is usually a holiday morning. Daughters-in-law get up before dawn and head for the in-laws’, stand in the kitchen frying jeon, and move back and forth past the living room while the men of the family watch TV. When the holiday ends, the headaches and indigestion and listlessness roll in — and Korea has a separate name for that too: 명절증후군 (myeongjeoljeunghugun), ‘holiday syndrome.’ It isn’t a clinical diagnosis, but it’s widely used in news articles and everyday conversation. 시월드, then, is the name for where that syndrome comes from.
Dramas and webtoons have been working this world for a long time. 《며느라기》 (Myeoneuragi, KakaoTV, 2020), a drama adapted from a webtoon, holds a magnifying glass to the subtle moments a new daughter-in-law goes through at her in-laws’; with no big incidents at all, it builds its conflict out of silences at the dinner table and a single term of address. The scenes viewers reacted to most strongly usually weren’t the ones with shouting — they were the ones where nobody is a villain and yet the daughter-in-law is the only one who keeps getting up from the table.
That said, this world is thinning out little by little. More couples now split the holidays evenly between his family and hers, and plenty of households simply take a trip instead. So these days the word 시월드 carries an extra note of ‘I can’t believe this is still a thing.’ That’s exactly why the word is worth knowing if you’re learning Korean. Learn 시월드 and you don’t just get a word — you get a look at the point a whole society is passing through right now.
Today’s Quiz
Which of the following uses 시월드 (siwoldeu) awkwardly?
- (to a friend) 이번 주말에 또 시월드 가야 해.
- (a husband to his wife) 나도 처가 가는 거 부담돼. 나한테도 시월드가 있다니까.
- (on an anonymous message board) 시월드 명절 스트레스, 어떻게들 견디시나요?
See the answer
The answer is 2. The prefix 시(媤) attaches only to relatives on the husband’s side, so a 시월드 can’t exist for a husband. Here he should say 처가 (cheoga) — or, if he wants to keep the joke alive, 처월드 (cheowoldeu). Both 1 and 3 are natural: each is said to peers with none of the family present.
