Korean describes what someone is like by talking about their body. Not their literal body — their eyes, hands, feet, and head stand in for their social instincts, their generosity, their connections, their brains. English does a little of this (she has a good head on her shoulders, he's all thumbs), but Korean has turned it into a single, highly productive grammatical frame that generates dozens of character descriptions. Learn the frame once and you can read them all — and, more importantly, you stop hearing 발이 넓다 as a comment about foot size.
The frame: person as topic, body part as subject
Every idiom on this page follows the same shape:
[사람]은/는 + [신체 부위]이/가 + [형용사] [the person] (topic) + [body part] (subject) + [descriptive verb]
The person is the topic (은/는): "as for him…". The body part is the grammatical subject (이/가). The descriptive verb predicates on that body part. So 그 사람은 발이 넓어요 is literally "as for him, the feet are wide" — and it means "he's well-connected." This is a classic double-subject construction: the sentence has a topic and a subject, and only by taking the whole thing as an idiom does the personality reading fall out. Read the body part literally and you get nonsense; read the frame idiomatically and you get a person.
눈: eyes, for perception and standards
눈치가 빠르다 — "to be quick to read a room, to be socially perceptive" (lit. "one's 눈치 is fast"). 눈치 is a whole cultural concept: the ability to read cues, sense the mood, and know what's expected without being told. Someone with fast 눈치 catches on instantly; its opposite, 눈치가 없다 ("to have no 눈치"), is socially oblivious.
우리 팀 막내가 눈치가 빨라서 분위기를 금방 파악해요.
uri tim mangnaega nunchiga ppallaseo bunwigireul geumbang paakaeyo
Our team's youngest reads the room fast — picks up on the mood right away.
그 사람은 눈치가 없어서 분위기 파악을 잘 못해요.
geu sarameun nunchiga eopseoseo bunwigi paageul jal motaeyo
He's oblivious — he can't read the mood at all.
눈이 높다 — "to have high standards, to be picky" (lit. "the eyes are high"), typically about romantic partners or quality. Its opposite, 눈이 낮다, means undemanding.
우리 언니는 눈이 높아서 아무나 안 만나요.
uri eonnineun nuni nopaseo amuna an mannayo
My older sister has high standards, so she won't date just anyone.
눈이 높은 것도 좋지만, 너무 따지면 결혼 못 해요.
nuni nopeun geotdo jochiman, neomu ttajimyeon gyeolhon mot haeyo
Having standards is fine, but if you're too picky you'll never get married.
손: hands, for generosity and speed
손이 크다 — "to be generous, to do things on a large scale" (lit. "the hand is big"). It describes someone who cooks enormous quantities, gives freely, spends liberally. It says nothing about actual hand size.
어머니는 손이 커서 명절만 되면 음식을 한가득 하세요.
eomeonineun soni keoseo myeongjeolman doemyeon eumsigeul hangadeuk haseyo
Mom cooks in huge quantities — every holiday she makes a mountain of food.
손이 크셔서 늘 필요한 것보다 많이 사세요.
soni keusyeoseo neul piryohan geotboda mani saseyo
She's generous to a fault — always buys more than we need.
손이 빠르다 — "to be quick-handed, to work fast and efficiently" (lit. "the hands are fast"). A prized trait in kitchens and workplaces.
새로 온 직원이 손이 빨라서 일 처리를 아주 신속하게 해요.
saero on jigwoni soni ppallaseo il cheorireul aju sinsokage haeyo
The new hire works fast — handles everything very quickly.
발: feet, for connections
발이 넓다 — "to be well-connected, to know everyone" (lit. "the feet are wide"). The image is of someone whose feet have carried them everywhere, so they know people in every circle. It is a social compliment, not a shoe size.
그 선배는 발이 넓어서 모르는 사람이 없어요.
geu seonbaeneun bari neolbeoseo moreuneun sarami eopseoyo
That senior is so well-connected there's no one he doesn't know.
발이 넓으면 취업할 때도 도움이 많이 돼요.
bari neolbeumyeon chwieopal ttaedo doumi mani dwaeyo
Being well-connected helps a lot when you're job hunting too.
머리: the head, for intelligence
머리가 좋다 — "to be smart" (lit. "the head is good"); 머리가 나쁘다 is its opposite. This one is the most transparent to English speakers, but note it still uses the frame: the head is the subject, the person is the topic.
걔는 머리가 좋아서 뭐든지 금방 배워요.
gyaeneun meoriga joaseo mwodeunji geumbang baewoyo
That kid's smart — picks up anything fast.
머리는 좋은데 노력을 안 해요.
meorineun joeunde noryeogeul an haeyo
He's smart, but he doesn't put in the effort.
입 and 귀: mouths and ears
The frame extends freely. 입이 무겁다 ("the mouth is heavy") = discreet, good at keeping secrets; 입이 가볍다 ("the mouth is light") = a blabbermouth. 귀가 얇다 ("the ears are thin") = easily swayed, gullible about what people tell you.
그 친구는 입이 무거워서 비밀을 말해도 안심이 돼요.
geu chinguneun ibi mugeowoseo bimireul malhaedo ansimi dwaeyo
That friend keeps secrets well, so I feel safe telling her things.
걔는 입이 가벼워서 소문이 금방 퍼져요.
gyaeneun ibi gabyeowoseo somuni geumbang peojeoyo
She's got a loose mouth — rumors spread fast through her.
우리 아빠는 귀가 얇아서 광고만 보면 다 사요.
uri appaneun gwiga yalbaseo gwanggoman bomyeon da sayo
My dad's easily swayed — he buys anything he sees advertised.
Because they all share the frame, you can stack several to paint a full portrait, keeping the person as the single topic and each body part as its own subject:
그 사람은 발이 넓고 눈치도 빨라서 사회생활을 참 잘해요.
geu sarameun bari neolgo nunchido ppallaseo sahoesaenghwareul cham jalhaeyo
He's well-connected and quick on the uptake, so he's great at navigating people.
Common Mistakes
1. Reading the idiom literally. The single biggest error is hearing 발이 넓다 as a description of feet or 손이 크다 as big hands. These are frozen character descriptions. If the sentence is about a person's personality, the body part is figurative.
✅ 그 사람은 발이 넓어요.
geu sarameun bari neolbeoyo
He's well-connected. (figurative — never a comment on actual foot size)
2. Putting the trait on the wrong subject. The body part is the 이/가-subject and the person is the topic. Learners sometimes force the person to be the only subject and drop the body-part subject, which breaks the idiom. The natural frame keeps both.
❌ 그 사람이 넓어요.
Incorrect — dropping the body part breaks the idiom; '그 사람이 넓어요' just means the person is physically wide, not that they're well-connected.
✅ 그 사람은 발이 넓어요.
geu sarameun bari neolbeoyo
He's well-connected.
3. Using 이/가 on the person where 은/는 is natural. These sentences topicalize the person: 그 사람은 발이 넓어요. Marking the person with 이/가 instead (그 사람이 발이 넓어요) is grammatical but shifts the nuance to "he's the one who's well-connected," which is rarely what you mean.
4. Confusing perception idioms with literal senses. 눈이 높다 is about standards, not eyesight; 귀가 얇다 is about being gullible, not ear thickness. Keep the metaphor in view.
Key Takeaways
- The frame is [사람]은 + [신체 부위]이/가 + [형용사] — a double-subject idiom where the body part describes character.
- 눈치가 빠르다 (perceptive) · 눈이 높다 (picky) · 손이 크다 (generous) · 손이 빠르다 (fast worker) · 발이 넓다 (well-connected) · 머리가 좋다 (smart) · 입이 무겁다/가볍다 (discreet/gossipy) · 귀가 얇다 (easily swayed).
- Always read the body part figuratively when it sits in this frame.
- One idiom, 배가 아프다, breaks the pattern by flipping between literal ("my stomach hurts") and figurative ("I'm jealous") — see 배가 아프다.

- 배가 아프다: When 'My Stomach Hurts' Means JealousTOPIK 3 — The same string 배가 아프다 means both 'my stomach hurts' and 'I'm green with envy' — and only the situation, not the grammar, tells you which; a lesson in how context switches a body collocation from literal to figurative.
- 마음 · 기분 · 속: The Three 'Hearts' and Their VerbsTOPIK 2 — Korean splits the English 'heart/feelings' into three inner-state nouns — 마음 (durable heart/mind), 기분 (passing mood), and 속 (guts, where hurt lives) — each locked to its own verb and particle.
- Double-Subject Constructions (코끼리는 코가 길다)TOPIK 3 — One Korean clause can carry two subject-like nominals — 코끼리는 코가 길다, 'as for elephants, the trunk is long' — where the first names the whole or possessor and the second is what the predicate actually describes.
- The Subject Particle 이/가TOPIK 1 — 이/가 marks the grammatical subject — the doer or experiencer — and presents it as new, noticed, or specifically selected, which is exactly why it is not interchangeable with the topic particle 은/는.
