-느라고 vs -는 바람에: Two Ways to Say 'Because' in Korean
Written and reviewed by Jun and Jin, native Korean speakers
Published · How we write & review
After this page, you can choose between -느라고, -는 바람에, and -아/어서 when explaining why something (usually bad) happened.
10-second answer
The short answer
-아/어서 (-a/eoseo) is the neutral "because" and works almost anywhere. -느라고 (-neurago) means "because I was busy doing X" — the cause is an activity that took up your time or energy, and the result is usually negative. -는 바람에 (-neun barame) means "because X suddenly happened" — an unexpected event knocked things off course, again with a bad result. Pick -느라고 when you were doing the cause; pick -는 바람에 when the cause happened to you.
Quick check — did that land?
1. "I couldn't answer because I was driving." Which connector fits best?
공부하느라고 늦었어요! 비가 오는 바람에 늦었어요! The first is being busy doing something. What about the second?
Side by Side
| Connector | Cause is… | Result is… | Same subject? | Past tense before it? |
|---|---|---|---|---|
| -아/어서 | anything | anything (neutral) | either | no (never -았어서) |
| -느라고 | an activity you were doing | negative — no time, tired, late, forgot | yes, always | no |
| -는 바람에 | a sudden, unexpected event | negative — plans fell through | either | no (use present -는) |
The one-line test
If you can naturally add "…so I didn't have time to / didn't get to…" it's -느라고. If you can add "…out of nowhere…" it's -는 바람에. If neither fits, use -아/어서.

Quick Examples
시험 공부하느라고 밤을 새웠어요.
siheom gongbuhaneurago bameul saewosseoyo.
I stayed up all night because I was studying for the exam.
-느라고: the studying consumed the night. Same subject does both halves.
전화 받느라고 못 들었어요.
jeonhwa banneurago mot deureosseoyo.
I didn't hear it because I was on the phone.
Classic -느라고 shape: doing X, so couldn't do Y. Note 받다 → 받느라고 with no past tense marker.
지하철이 고장 나는 바람에 지각했어요.
jihacheori gojang naneun barame jigakaesseoyo.
I was late because the subway broke down.
-는 바람에: the breakdown happened to me. The subject of the cause (지하철) is different from the result (I).
갑자기 손님이 오는 바람에 약속을 취소했어요.
gapjagi sonnimi oneun barame yaksogeul chwisohaesseoyo.
I cancelled the plan because a guest showed up unexpectedly.
갑자기 (suddenly) pairs naturally with -는 바람에 — the ending already carries that 'out of nowhere' feeling.
비가 와서 집에 있었어요.
biga waseo jibe isseosseoyo.
I stayed home because it rained.
Neutral -아/어서 — no blame, no surprise. Compare 비가 오는 바람에 못 갔어요, which stresses that rain ruined the plan.
Rules Each Connector Breaks
-느라고 has two hard restrictions. First, the verb before it must be an action you actively do (공부하다, 일하다, 준비하다) — never an adjective or a passive state, so 아프느라고 ✗. Second, the subject of both clauses must be the same person: you can't say 동생이 노느라고 제가 못 잤어요; that needs -아/어서 or -는 바람에. It also never takes past tense: 공부했느라고 ✗ → 공부하느라고 ✓, because the timing is understood from the main verb.
-는 바람에 is looser about subjects but strict about tone: the result has to be something that went wrong. 비가 오는 바람에 시원했어요 ("thanks to the rain it was cool") sounds odd — for a good outcome use -아/어서 or the gratitude connector -(으)ㄴ 덕분에 (비가 온 덕분에 시원했어요). Structurally it's just the present modifier -는 plus the noun 바람 ("gust, effect") and the particle 에, which is why the verb before it stays in present tense even for past events.
-아/어서 is the safe default, but remember it can't carry a past-tense marker (갔어서 ✗ → 가서 ✓) and it can't be followed by a command or suggestion — for those, switch to -(으)니까 (see an vs mot for another pair where the ending changes what you're allowed to say next).
Another pair with its own subject rules is -(으)면서 vs -는 동안, two ways to say "while."
Common Mistakes
Mistake #1 — -느라고 with an adjective
바쁘느라고 ✗. Adjectives describe a state, not an activity — say 바빠서 instead.
Mistake #2 — Different subjects around -느라고
아이가 우느라고 저는 못 잤어요 ✗ → 아이가 우는 바람에 저는 못 잤어요 ✓. When someone else's action caused your problem, that's -는 바람에.
Mistake #3 — -는 바람에 for a happy result
친구가 도와주는 바람에 잘 끝났어요 ✗ → 친구가 도와준 덕분에 잘 끝났어요 ✓. 바람에 blames; 덕분에 thanks.
