Most body-part idioms are frozen into one meaning — 발이 넓다 always means "well-connected," never literally "wide feet." 배가 아프다 is the fascinating exception: it lives a double life. After a heavy meal it means exactly what it says — "my stomach hurts." But when a friend just landed a great job, the identical string means "I'm jealous." Nothing in the grammar changes; the situation does all the work of switching the meaning. That makes this idiom a perfect little case study in how Korean lets context, not morphology, flip a phrase from literal to figurative.
The literal meaning: an actual stomachache
Start with the plain reading. 배 is "belly/stomach," it takes the subject particle 이/가, and the predicate is 아프다 ("to hurt, to be sick/sore"). 아프다 follows the regular 으-drop pattern: the stem-final ㅡ drops before an ending starting with 아/어, so 아프 + 아요 → 아파요, and the past is 아팠어요. This is the sentence you say at the pharmacy.
어제 매운 걸 많이 먹었더니 아침부터 배가 아파요.
eoje maeun geol mani meogeotdeoni achimbuteo baega apayo
I ate a lot of spicy food yesterday, so my stomach's been hurting since morning.
배가 너무 아파서 병원에 갔어요.
baega neomu apaseo byeong-wone gasseoyo
My stomach hurt so badly that I went to the hospital.
The figurative meaning: petty, begrudging envy
Now the twist. 배가 아프다 also means "to be jealous/envious of someone else's good fortune." It comes from a well-known proverb: 사촌이 땅을 사면 배가 아프다 — "when your cousin buys land, your belly aches." The image is precise and a little unflattering: watching a relative do well doesn't make you happy for them; it gives you a physical, gnawing discomfort. That is the flavor of this idiom — small-minded, begrudging envy, the human pang of why them and not me.
친구가 취직했다는 소식을 듣고 솔직히 좀 배가 아팠어요.
chinguga chwijikaetdaneun sosigeul deutgo soljiki jom baega apasseoyo
Honestly, I felt a twinge of envy when I heard my friend got the job.
나만 빼고 다 승진해서 배 아파 죽겠어.
naman ppaego da seungjinhaeseo bae apa jukgesseo
Everyone but me got promoted — I'm dying of jealousy.
사촌이 땅을 사면 배가 아프다는 속담처럼, 가까운 사람이 잘되면 더 배가 아픈 법이에요.
sachoni ttang-eul samyeon baega apeudaneun sokdamcheoreom, gakkaun sarami jaldoemyeon deo baega apeun beobieyo
As the proverb 'when your cousin buys land, your belly aches' goes, it stings even more when someone close to you does well.
Grammatically the figurative sentence is identical to the literal one: 배 is still the subject, 아프다 is still the predicate, and the experiencer (you) is the topic or simply dropped. 나는 배가 아파 is, on paper, ambiguous between a stomachache and a fit of envy.
How you tell them apart: only the situation
Because the grammar is the same, disambiguation is entirely situational — and native speakers do it effortlessly. Just ate? Literal. Just heard someone's good news? Envy. Speakers even play with the ambiguity for comic effect, pretending to have a stomachache when everyone knows it's jealousy.
배가 아프다더니, 이제 보니 부러워서 그런 거였어?
baega apeudadeoni, ije boni bureowoseo geureon geoyeosseo
You said your stomach hurt — but now I see it was just jealousy, wasn't it?
저 사람 잘나가는 거 보니까 배 아프죠? 솔직히 말해 봐요.
jeo saram jallaganeun geo bonikka bae apeujo? soljiki malhae bwayo
Seeing him do so well makes you a little jealous, right? Be honest.
The tone: self-aware and half-joking
This is not grand, dramatic jealousy. 배가 아프다 is petty and the speaker usually knows it's petty — which is why it carries a light, self-deprecating, half-joking tone. Admitting 나 지금 배 아파 is a way of confessing a small, human, slightly embarrassing feeling, often with a laugh. It is close to English "I'm so jealous!" said with a grin, or "sour grapes," not to a serious accusation.
야, 너 복권 당첨됐다고? 나 지금 완전 배 아파.
ya, neo bokgwon dangcheomdwaetdago? na jigeum wanjeon bae apa
Wait, you won the lottery? I'm so jealous right now.
시험 잘 봤다고 자랑하니까 친구들이 다 배 아파했어요.
siheom jal bwatdago jaranghanikka chingudeuri da bae apahaesseoyo
When I bragged about acing the exam, all my friends were green with envy.
동생이 새 휴대폰을 사서 좀 배가 아팠는데, 금방 잊어버렸어요.
dongsaeng-i sae hyudaeponeul saseo jom baega apanneunde, geumbang ijeobeoryeosseoyo
I was a little envious when my brother got a new phone, but I got over it fast.
To describe someone else's envy, use the verb form 배 아파하다 ("to feel/show envy"), just as you'd turn any adjective into an outward-behavior verb with -아/어하다.
남 잘되는 걸 보고 배 아파하지 말고, 너도 열심히 하면 되잖아.
nam jaldoeneun geol bogo bae apahaji malgo, neodo yeolsimhi hamyeon doejana
Instead of begrudging others' success, just work hard yourself.
Not all envy is 배가 아프다: 부럽다 and 질투하다
This is where English speakers most need steering, because English uses "jealous" and "envious" loosely. Korean draws sharper lines:
- 부럽다 — clean, open, often admiring envy: "I wish I had that." No pettiness implied. It's the polite, honest thing to say to someone's face.
- 배가 아프다 — begrudging, petty envy you'd rather not admit. Said about yourself with a rueful laugh, rarely as a compliment.
- 질투하다 / 질투가 나다 — jealousy in the possessive, romantic sense: fearing you'll lose someone's attention. This is emotionally different and is never 배가 아프다.
나는 네가 부러워. 나도 그렇게 여행 많이 다니고 싶어.
naneun nega bureowo. nado geureoke yeohaeng mani danigo sipeo
I envy you. I wish I could travel that much too.
친구가 부러운 건 자연스러운 감정이에요.
chinguga bureoun geon jayeonseureoun gamjeong-ieyo
Envying a friend is a perfectly natural feeling.
남자친구가 다른 여자랑 얘기하면 질투가 나요.
namjachinguga dareun yeojarang yaegihamyeon jiltuga nayo
I get jealous when my boyfriend talks to other women.
Common Mistakes
1. Always taking it literally. Beginners hear 배 아파 after good news and picture a stomachache, missing the joke entirely. When the trigger is someone else's success, it's envy.
✅ 나 좀 배 아프다.
na jom bae apeuda
(after a friend passed) I'm a little jealous.
2. Using 배가 아프다 for romantic jealousy. Possessive, romantic jealousy is 질투가 나다 / 질투하다, never 배가 아프다. Say 질투가 나요, not ×배가 아파요, when you mean you're jealous of a partner's attention.
❌ 남자친구 때문에 배가 아파요.
Wrong sense (intended: romantic jealousy) — 배가 아프다 is envy of good fortune, not romantic jealousy; use 질투가 나요.
✅ 남자친구 때문에 질투가 나요.
namjachingu ttaemune jiltuga nayo
I feel jealous because of my boyfriend.
3. Using it for grand, admiring envy. If you genuinely, warmly admire what someone has and want to say so to their face, use 부럽다. 배가 아프다 is the petty version and can sound sarcastic or ungenerous if aimed at them directly.
❌ 선생님, 정말 대단하세요. 배가 아파요.
Off-key — sounds petty/sarcastic to someone's face; use 부럽습니다 for sincere admiration.
✅ 선생님, 정말 대단하세요. 부럽습니다.
seonsaengnim, jeongmal daedanhaseyo. bureopseumnida
You're amazing — I really admire you. (formal)
Key Takeaways
- 배가 아프다 = literally "my stomach hurts," figuratively "I'm (pettily) jealous of someone's good fortune."
- The grammar is identical either way; only the situation disambiguates — a meal → literal, someone's good news → envy.
- The envy sense is petty and self-aware, usually said about oneself half-jokingly (나 배 아파).
- Keep three "jealous" words apart: 부럽다 (open, admiring envy), 배가 아프다 (petty, begrudging envy), 질투하다 (romantic/possessive jealousy). For how such sayings are quoted, see 속담 vs 사자성어.
