생기다 · 들다 · 걸리다: Verbs That Live in Fixed Collocations

Some Korean verbs barely carry meaning on their own. 걸리다, 들다, and 생기다 are three of the most common of these: their everyday sense lives in the collocation, in the specific noun they pair with, not in the verb alone. That is good news and bad news. Bad, because you cannot deduce 감기에 걸리다 ("to catch a cold") from a dictionary gloss of 걸리다. Good, because once you memorize the noun-plus-verb unit — and the particle welded to it — you own a whole family of natural phrases at once. This page pins down all three verbs, their imagery, and the particle each demands.

걸리다 — "to get caught / hung on / snagged"

걸리다 is the passive of 걸다 ("to hang"), and that origin explains everything. To be 걸리다 is to be hooked, hung up, snagged on something — and that image runs through all its collocations.

A cold hooks onto you, so the illness takes the locative 에: 감기에 걸리다. Any illness works this way — 병에 걸리다, 독감에 걸리다. The other big use of 걸리다 is elapsed time: how long something takes.

Here the duration is the thing that "hangs" — the process snags you for a stretch — and it is the subject, so it takes 이/가: 시간이 걸리다. The present 걸려요 and past 걸렸어요 come from 걸리 + 어요 / 었어요.

들다 — "to enter / go in / be required"

들다 has a core sense of going in, and its collocations are about resources — money, time, effort, even affection — that go into something.

돈이 들다 is the standard way to say to cost money: the money goes into the project. The same frame handles effort — 힘이 들다 ("to be tough / take a toll") — and, beautifully, attachment: 정이 들다, "affection enters," is how Korean says you grow fond of a person or place over time.

The past 들었어요 is 들 + 었어요 → 드러써요. (A cold can also be described with 감기가 들다 / 감기 들었어요 in casual speech, alongside the standard 감기에 걸리다 — good to recognize, but 걸리다 is the safe default.)

생기다 — "to come into being / form / arise"

생기다 turns nothing into something. Whatever did not exist a moment ago and now does — a problem, a plan, a relationship, some cash — 생기다 is the verb.

여자친구가 생기다 does not mean a girlfriend exists — it means one came into your life, out of a previous state of not having one. The subject takes 이/가. The past 생겼어요 is 생기 + 었어요 → 생겨써요.

Two more everyday uses you'll hear constantly

Because 들다 is "to enter," it also gives Korean its main verb for liking an object: 마음에 들다 — literally "to enter one's heart." Something you find pleasing enters your heart, so it takes the locative 에. This is how you say you like a thing (as opposed to 좋아하다 for people and activities).

And 걸리다 keeps its "snagged / hooked" image in a second big sense: to get caught. You get caught at a red light, caught cheating, caught by the teacher — hooked by something you didn't want to be hooked by.

The near-synonym trap: 걸리다 vs 들다 for "take / cost"

English uses "take" and "cost" loosely, so learners swap 걸리다 and 들다 at random. Korean keeps them separate along a clean line:

So duration is 걸리다, but money is 들다 — never the reverse. 돈이 걸려요 and 시간이 드는 데 두 시간… are the classic swaps. The mnemonic: 걸리다 is time hanging over you (a clock running), 들다 is a resource going into the pot (money poured in).

Why English speakers get this wrong

Three transfer errors dominate. First, "I have a cold" tempts 감기가 있어요 or ×감기를 해요 — but Korean conceptualizes catching a cold as getting hooked by it: 감기에 걸리다. Second, "it takes/costs" collapses 걸리다 and 들다; keep duration on 걸리다 and money/effort on 들다. Third, "I got a girlfriend / a problem came up" tempts 있다 ("to exist"), but 있다 states a static fact, while 생기다 marks the coming-into-being — the change from not-having to having. 여자친구가 있어요 means "I have a girlfriend (right now)"; 여자친구가 생겼어요 means "I've gotten one (just now)."

Common Mistakes

Lock the noun, particle, and verb together as one unit and these fade. For the closely related spontaneous/caused pair, see 나다 vs 내다; for the 하다-based light verbs, 하다 light-verb collocations; and for the 있다/없다 existence contrast that 생기다 plays against, 있다 · 없다: existence vs adjective.
