-고 나면
After Doing, Once
-고 나면 is used to express that once an action is completed, a particular situation, state, or another action naturally follows. It translates to 'after doing...' or 'once you do...'.
How It Works
-고 나면 is used to connect two clauses where the second clause is a result or a state that naturally occurs after the action in the first clause is fully completed. It often carries a conditional or hypothetical nuance, similar to 'if/when you finish doing X, then Y happens'.
Key Nuances:
- Completion is Key: It stresses that the first action must be finished for the second part to happen.
- Natural Consequence: The second clause is often an expected or logical outcome. For example, 'After you exercise, you feel refreshed.'
- General Truths & Advice: It's frequently used to state general truths or give advice based on a cause-and-effect relationship.
Comparison with similar patterns:
- -고 나서: This simply indicates a sequence of events ('do A, and then do B'). It's used for specific, one-time actions.
e.g., 어제 숙제를 하고 나서 잤어요. (Yesterday, after doing my homework, I slept.) - -고 나면: This implies a general or recurring consequence. It would be unnatural to use it for a specific past event like the one above.
e.g., 숙제를 다 하고 나면 기분이 좋아요. (Once you finish your homework, you feel good.) - -고 나니까: This is used when the speaker makes a personal discovery or realizes something new after completing an action.
e.g., 약을 먹고 나니까 머리가 안 아파요. (After taking the medicine, I realized my head doesn't hurt anymore.)
The verb before -고 나면 is always in its stem form, without any tense markers. The overall tense of the sentence is determined by the final verb.

Common Mistakes
Using -고 나면 for a simple sequence of past events.
Not Quite어제 영화를 보고 나면 집에 갔어요.Better어제 영화를 보고 나서 집에 갔어요.-고 나면 implies a general consequence or future outcome, not a specific, one-time sequence of actions in the past. For simple sequences, -고 나서 or -ㄴ 다음에/후에 is more appropriate.
Adding past tense to the verb before -고 나면.
Not Quite숙제를 다 했고 나면 놀러 갈 거예요.Better숙제를 다 하고 나면 놀러 갈 거예요.The verb attached to -고 나면 must be in its dictionary stem form. The tense of the entire sentence is indicated by the final verb (갈 거예요).
