TL;DR 🦄
- -느라고 [-neu-ra-go] means because someone was busy doing X / while doing X, usually leading to a negative or inconvenient result.
- It attaches to action verb stems: 공부하다 → 공부하느라고, 먹다 → 먹느라고, 기다리다 → 기다리느라고.
- Beginner rule: the subject of both parts is usually the same, and the result should be a statement — not a command or suggestion.

🌈 The Big Picture
-느라고 explains a reason by saying someone was occupied with one action, and because of that, another result happened.
The result is often:
- negative 😵
- inconvenient 🫠
- tiring 😴
- something missed or not done ❌
Think:
- I was busy doing X, so Y happened.
- Because I was doing X, I couldn’t do Y.
- While doing X, Y happened.
Examples:
- 숙제하느라고 못 갔어요. [suk-je-ha-neu-ra-go mot ga-sseo-yo] (I couldn’t go because I was doing homework.) ✏️
- 전화하느라고 못 들었어요. [jeon-hwa-ha-neu-ra-go mot deu-reo-sseo-yo] (I didn’t hear because I was on the phone.) 📞
- 늦잠을 자느라고 늦었어요. [neut-ja-meul ja-neu-ra-go neu-jeo-sseo-yo] (I was late because I overslept.) 😴
🎨 The Core Pattern
Attach -느라고 to an action verb stem.
- 공부하다 [gong-bu-ha-da] (to study) → 공부하느라고 [gong-bu-ha-neu-ra-go]
- 일하다 [il-ha-da] (to work) → 일하느라고 [il-ha-neu-ra-go]
- 먹다 [meok-da] (to eat) → 먹느라고 [meong-neu-ra-go]
- 읽다 [ik-da] (to read) → 읽느라고 [ing-neu-ra-go]
- 기다리다 [gi-da-ri-da] (to wait) → 기다리느라고 [gi-da-ri-neu-ra-go]
- 자다 [ja-da] (to sleep) → 자느라고 [ja-neu-ra-go]
Basic formula:
- Action verb stem + 느라고 + result
- 일하느라고 피곤해요. (I’m tired because I was working.) 💼
- 게임하느라고 잠을 못 잤어요. (I couldn’t sleep because I was playing games.) 🎮
🛠️ How It Works in a Sentence
- 시험공부하느라고 친구를 못 만났어요. [si-heom-gong-bu-ha-neu-ra-go chin-gu-reul mot man-na-sseo-yo] (I couldn’t meet my friend because I was studying for an exam.) 📝
- 시험공부하다 = to study for an exam, 친구를 만나다 = to meet a friend, 못 = cannot.
- 요리하느라고 손을 다쳤어요. [yo-ri-ha-neu-ra-go so-neul da-chyeo-sseo-yo] (I hurt my hand while cooking / because I was cooking.) 🍳
- 요리하다 = to cook, 손 = hand, 다치다 = to get hurt.
- 친구를 기다리느라고 늦었어요. [chin-gu-reul gi-da-ri-neu-ra-go neu-jeo-sseo-yo] (I was late because I was waiting for my friend.) ⏰
- 기다리다 = to wait, 늦다 = to be late.
🧩 General Formation Rule
Action verbs
- Dictionary form → remove 다 → add 느라고
- 가다 → 가느라고
- 보다 → 보느라고
- 먹다 → 먹느라고
- 찾다 → 찾느라고
- 공부하다 → 공부하느라고
ㄹ-ending action verbs
Drop ㄹ before 느라고.
- 놀다 → 노느라고 (because someone was playing) 🎮
- 만들다 → 만드느라고 (because someone was making) 🛠️
- 살다 → 사느라고 (because someone was living) 🏠
Use with action verbs, not descriptive adjectives
- ✅ 일하느라고 피곤해요. (I’m tired because I was working.)
- ❌ 피곤하느라고 못 갔어요. (Do not use -느라고 with “being tired” as the action.)
- ✅ 피곤해서 못 갔어요. or 피곤하기 때문에 못 갔어요. (I couldn’t go because I was tired.)
No past/future marker before -느라고
For beginner Korean, do not put -았/었- or -겠- before 느라고.
- ❌ 공부했느라고 피곤해요.
- ✅ 공부하느라고 피곤해요.
- ✅ 공부했기 때문에 피곤해요.
🧭 Important Usage Limits
-느라고 has stricter rules than -기 때문에.
1. Same subject
Usually, the person doing the first action is also connected to the result.
- ✅ 제가 숙제하느라고 못 갔어요. (I couldn’t go because I was doing homework.)
- ❌ 동생이 자느라고 제가 못 잤어요. (Different subjects: younger sibling slept, I couldn’t sleep.)
- ✅ 동생이 잤기 때문에 제가 못 잤어요. (Because my younger sibling slept, I couldn’t sleep.)
2. Result is usually negative or inconvenient
Natural results:
- 못 갔어요 (couldn’t go)
- 늦었어요 (was late)
- 피곤해요 (am tired)
- 못 들었어요 (didn’t hear)
- 실수했어요 (made a mistake)
3. Do not use commands or suggestions after -느라고
- ❌ 숙제하느라고 일찍 잡시다.
- ✅ 숙제해야 하니까 일찍 잡시다. (Because we have to do homework, let’s sleep early.)
- ✅ 숙제하느라고 못 잤어요. (I couldn’t sleep because I was doing homework.)
🧭 -느라고 vs -기 때문에
Both can explain reasons, but they behave differently.
-느라고
- action-activity reason
- same subject
- often negative/inconvenient result
- no command/suggestion in the result
- no past/future marker before it
Example:
- 전화하느라고 못 들었어요. (I didn’t hear because I was on the phone.) 📞
-기 때문에
- more general and flexible
- can use different subjects
- can use past tense
- can appear with commands/suggestions more freely
Example:
- 전화했기 때문에 못 들었어요. (Because I made/was on a call, I didn’t hear.) 📞
- 동생이 전화했기 때문에 제가 못 들었어요. (Because my younger sibling called, I didn’t hear.) 📞
Tiny feeling note: -느라고 often sounds like “I was caught up doing X,” so it is great for explaining excuses or inconveniences.
📚 Cross-check note
The constraints of -느라고 — same subject, no command/suggestion in the following clause, and no past/future marker before it — plus its contrast with -기 때문에, were cross-checked against korean.go.kr. ✅
🪞 Synonym Alert
These all explain reasons, but they are not identical:
- -느라고 [-neu-ra-go] → because/while doing; action took time/attention and caused a result 🏃
- -기 때문에 [-gi ttae-mu-ne] → because; strong and flexible reason 💪
- 아서/어서 [a-seo/eo-seo] → because/so; smooth reason-result bridge 🌉
- -(으)니까 [-(eu)-ni-kka] → because/since; useful for requests and suggestions 🧭
⚠️ Pitfalls to Dodge
- ❌ 공부했느라고 피곤해요. → ✅ 공부하느라고 피곤해요. (Do not use past marker before 느라고.) 📝
- ❌ 먹으느라고 늦었어요. → ✅ 먹느라고 늦었어요. (No extra 으 for consonant stems.) 🍚
- ❌ 노느라고? → ✅ Yes, 놀다 drops ㄹ: 노느라고. 🎮
- ❌ 바쁘느라고 못 갔어요. → ✅ 바빠서 못 갔어요. or 바쁘기 때문에 못 갔어요. (Use -느라고 with action verbs.) 📅
- ❌ 숙제하느라고 빨리 가세요. → ✅ 숙제해야 하니까 빨리 가세요. (Do not use -느라고 before commands.) 🧭
Now you can explain why something went wrong, got delayed, or couldn’t happen: -느라고 shows the action that swallowed your time and attention. 🏃✨
