-어 내다
-어 내다: Manage To… — Push Through Until Done
Auxiliary 내다 after -어: the action is carried through by one’s own power, often through difficulty.
How to form it
| When | Form | Example |
|---|---|---|
| Verb + -아/어 내다 | -아/어 내다 | 참아 내다 / 이겨 내다 / 막아 내다 |
| 하다 (hada) verbs | 해 내다 | 해 내다 / 견뎌 내다 |
-어 내다 means manage to… — pushing through until it is done.
Why this is hard
It adds effort and completion colour to the verb. Learners treat it as bare -다 or confuse it with benefactive -어 주다. The 내다 piece is ‘bring it out / see it through.’
What it does
You mark an action completed through difficulty or persistence.

Forms
Verb stem + -아/어 내다.
When not to use it
Do not use it for easy, effortless actions. Do not confuse it with -어 주다 giving. Do not stack it on every verb for emphasis.
Neighbours — and why they differ
| Form | Why it is not this slot |
|---|---|
| -어 주다 | Do for someone — benefactive. |
| -어 버리다 | End up doing — completion with emotion. |
| -고 말다 | End up doing — different path. |
Survival, discovery, and endurance stories love this. Keep a real obstacle in the scene.
Classroom examples should keep the meaning concrete: one clear scene beats three vague glosses. If a neighbour form already says the same thing more lightly, prefer the lighter tool unless register demands this one.
Ask: did someone push through until it was done? If yes, -어 내다. If they did a favour, use -어 주다.
