-느라고
Because I was busy doing…
Connect an activity with its consequences. Learn the form, compare familiar reason patterns, and check your understanding with six practice questions.

A situation you already know
Someone called while you were in a meeting. You want to explain why you could not answer:
I couldn’t answer the phone because I was in a meeting.
V-느라고 connects an activity that occupied someone’s time or attention with a difficulty, missed action, or tiring result. A useful English guide is “because I was busy doing…” or “I was doing…, so I couldn’t…”. The activity itself need not be bad.
Build the form
만들다 → 만들- → 만드- → 만드느라고
Remove 다 → drop ㄹ if present → attach 느라고.
- Remove 다 and attach 느라고: 하다 → 하느라고; 먹다 → 먹느라고; 찾다 → 찾느라고.
- Drop final ㄹ: 만들다 → 만드느라고; 놀다 → 노느라고. Do not add 으.
- Keep other stems before this consonant: 듣다 → 듣느라고; 돕다 → 돕느라고.
- Use an action verb. For a state such as 바쁘다, use 바빠서, not 바쁘느라고.
- Do not put 았/었 or 겠 directly before 느라고 in this pattern. 어제 일하느라고 못 갔어요 describes the past through 어제 and 못 갔어요.
Think in Korean, not word-for-word English
English because introduces a whole clause: “I couldn’t answer because I was working.” Korean attaches 느라고 to the first verb and normally puts the cause before the result: 일하느라고 + 전화를 못 받았어요. You do not need a separate word for “busy”; the construction already presents the activity as occupying time or attention.
English can put a different subject in each because-clause. In the core -느라고 pattern, keep the same person doing the activity and experiencing the result. That person may be I, you, or someone else: this is not a first-person-only rule.
Six examples in context
I couldn’t answer the phone because I was in a meeting.
I didn’t get enough sleep yesterday because I was studying for an exam.
I was late meeting my friend because I was working overtime.
I missed lunch because I was looking for the materials.
I missed the announcement because I was talking with a friend.
Minsu couldn’t rest over the weekend because he was moving.
-느라고 vs -아/어서: what changes?
-아/어서
회의를 해서 전화를 못 받았어요.“I couldn’t answer because I had a meeting.” This presents the meeting as the reason. The context may still imply that it occupied me, but the ending itself is a broader cause connector.
-느라고
회의를 하느라고 전화를 못 받았어요.“I was tied up in a meeting, so I couldn’t answer.” Time or attention was occupied by the meeting. This is a natural choice when explaining a missed call.
Where substitution fails: 아파서 못 갔어요 (“I couldn’t go because I was sick”) describes a state, not an activity: ✗ 아프느라고. 비가 와서 늦었어요 describes an external event: ✗ 비가 오느라고. 열심히 공부해서 합격했어요 presents a welcome result; -느라고 is not the ordinary connector for that meaning.
Beginner review · related patterns
-(으)니까
지금 회의 중이니까 나중에 전화해 주세요.Since I’m in a meeting, please call later. The reason supports a request; it does not describe an activity preventing another one.
-기 때문에
회의 중이었기 때문에 전화를 못 받았어요.Because I was in a meeting, I couldn’t answer. An explicit cause statement, without requiring the time-and-attention reading.
-(으)면서
음악을 들으면서 공부했어요.I studied while listening to music. Two activities happen together; no failed outcome is implied.
-는 동안
제가 회의하는 동안 동료가 전화를 받았어요.My colleague answered the phone while I was in a meeting. This gives a time window and allows different subjects.
Intermediate connections · cause and outcome
Preview these contrasts as you continue the intermediate course. They are related by function, not interchangeable endings.
-는 바람에
회의가 갑자기 길어지는 바람에 막차를 놓쳤어요.The meeting unexpectedly ran long, so I missed the last train. Focus: an unwelcome event. Unlike -느라고, the cause need not be my own activity.
-(으)ㄴ/는 탓에
밤늦게까지 게임을 한 탓에 아침에 늦게 일어났어요.I woke up late because I had played games late into the night. This assigns the unwanted result to a cause and often sounds more blaming or self-critical. It does not require simultaneous competition between activities.
-(으)ㄴ 덕분에
친구가 도와준 덕분에 일을 일찍 끝냈어요.Thanks to my friend’s help, I finished early. This positively evaluates the cause. Use it for helpful causes, not as a synonym for the core negative-result -느라고 pattern.
With 탓에 and 덕분에, a completed action often takes -(으)ㄴ: 한 탓에, 도와준 덕분에. A current or ongoing action can take -는. 덕분에 can also be used ironically, but that is not the neutral use practiced here.
Common mistakes and useful limits
- ✗ 일했느라고 → ✓ 일하느라고. Put past time in the final predicate: 일하느라고 늦었어요.
- ✗ 바쁘느라고 못 갔어요 → ✓ 바빠서 못 갔어요. Or specify the activity: 일하느라고 못 갔어요.
- ✗ 비가 오느라고 늦었어요 → ✓ 비가 와서 늦었어요.
- To say “I was late because my child was crying,” use 아이가 울어서 제가 늦었어요. To use -느라고 with your own activity: 아이를 달래느라고 늦었어요, “I was late because I was soothing my child.”
- Do not treat -느라고 as the ordinary connector for a welcome achievement. 공부를 열심히 해서 시험에 합격했어요 naturally says “I passed the exam because I studied hard.”
Use it considerately
못 받아서 죄송해요. 회의하느라고 전화를 못 받았어요. — “Sorry I missed your call. I was in a meeting.” The ending explains circumstances; it does not by itself express an apology. In repeated excuses, an explanation alone may sound defensive.
Mini practice
- Join with -느라고: 자료를 찾다 + 전화를 못 받았어요.
- Correct the verb form: 친구와 놀느라고 숙제를 못 했어요.
- Choose a cause connector: 비가 (오느라고 / 와서) 늦었어요.
- Translate: “Minsu couldn’t rest because he was moving.”
- For a request, choose: 지금 일하고 (있느라고 / 있으니까) 나중에 전화해 주세요.
- Write one sentence about an activity that kept you from doing something. Check the subject and the result.
Answers and explanations
- 자료를 찾느라고 전화를 못 받았어요. 찾- + 느라고.
- 친구와 노느라고 숙제를 못 했어요. 놀- loses ㄹ.
- 와서. Rain is an external cause, not the subject’s activity.
- 민수 씨는 이사하느라고 쉬지 못했어요. The same person moves and cannot rest.
- 있으니까. The reason supports a request.
- Example: 보고서를 쓰느라고 점심을 못 먹었어요. “I missed lunch because I was writing a report.” Other natural answers are possible.
Today’s key point
Activity taking time or attention → difficulty or missed action. Use V-느라고, keep the subject consistent, and mark past time at the end. Start with this core use, then recognize the broader effort-focused expressions.
