TOPIK II · LEVEL 5

-아/어 내다

-아/어 내다 shows that someone gets through something hard and carries it through to the end by their own effort or endurance.

시제·상Tense & aspect

Han: Eating an ordinary lunch takes no special effort, so -아/어 내다 does not fit; it is not a general 'did/finished' ending but implies overcoming difficulty.

Examples

그 어려운 시기를 버텨 낸 덕분에 지금의 회사가 있는 거예요.The company exists today because we held out through those hard times.
그는 힘든 수술을 견뎌 내고 다시 무대에 섰다.He got through a difficult surgery and stood on the stage again.
경찰은 오랜 수사 끝에 범인을 찾아냈다.After a long investigation, the police finally tracked down the culprit.
아이가 주사를 맞으면서도 울지 않고 끝까지 참아 냈어요.The child didn't cry and endured the injection to the end.

Don’t mix up

-아/어 내다vs-고 말다-고 말다 usually reports an outcome you could not prevent, while -아/어 내다 reports a success you fought for: 결국 울고 말았다 (couldn't help crying) vs 끝까지 참아 냈다 (managed not to cry).-아/어 내다vs-아/어 버리다-아/어 버리다 stresses that something is completely finished, often with relief or regret, with no idea of effort; -아/어 내다 stresses the struggle: 일을 다 끝내 버렸다 vs 힘든 일을 끝까지 해냈다.
-아/어 내다vs-(으)ㄹ 수 있었다-(으)ㄹ 수 있었다 only says it was possible, while -아/어 내다 adds that it was hard and you actually completed it: 문제를 풀 수 있었다 vs 어려운 문제를 끝까지 풀어 냈다.

How to build it

V+아/어 내다

견디다 → 견뎌 내다 → 견뎌 냈어요

  1. Use it only when the action is difficult or needs effort; with everyday, effortless actions (eating lunch, drinking coffee) it sounds strange.
  2. It attaches to action verbs, not adjectives, and the subject is usually a person or group that makes the effort, not something that happens by itself (비가 그쳐 냈다 is wrong).
  3. It is most often used in the past to report an achievement, but it also works with intentions and wishes: 꼭 이겨 낼 거예요.
  4. Some combinations have become single words and are written without a space: 해내다, 찾아내다, 밝혀내다.

Classic mistake

Wrong: 점심에 김밥을 먹어 냈어요.

Right: 점심에 김밥을 먹었어요.
