Because of [Action]

This pattern is used to connect an action with its consequence, where the consequence is typically negative, unintended, or involves some kind of cost (like being tired or late).

Meaning & Usage

Meaning: It indicates that the action in the first clause is the direct reason for the result in the second clause. It implies that the subject was so occupied with the first action that it led to the second outcome.

When to use: It's perfect for making excuses or explaining why you couldn't do something else. For example, I couldn't do my homework because I was playing (노느라고 숙제 못 했어).

Formation

Verb Stem + -느라고: Simply attach -느라고 to the stem of an action verb, regardless of whether it ends in a vowel or a consonant.

자다 (to sleep) → 자 + 느라고 → 자느라고

먹다 (to eat) → 먹 + 느라고 → 먹느라고

공부하다 (to study) → 공부하 + 느라고 → 공부하느라고

Key Constraints

Action Verbs Only: This pattern cannot be used with descriptive verbs (adjectives) like 아프다 (to be sick) or 예쁘다 (to be pretty).

Same Subject: The subject of both the reason clause and the result clause must be the same.

Simultaneous Action: The action in the -느라고 clause and the result happen at the same time or in close succession.

자느라고 전화 못 받았어. / 공부하느라고 밤샜어. / 준비하느라고 늦었어. / 영화 보느라고 버스를 놓쳤어.

Learners often confuse -느라고 with -아/어서, another common pattern for expressing reasons. However, they have distinct uses.

-느라고

Focus: An action that requires time and effort, leading to a negative or unintended consequence.

Simultaneity: The two events happen at the same time.

Example: 게임하느라고 숙제를 못 했어요. (I couldn't do my homework because I was playing games.)

Nuance: The act of playing games prevented me from doing homework during that same time.

-아/어서

Focus: A general, neutral reason for a result (can be positive or negative).

Sequence: The reason happens before the result.

Example: 늦게 일어나서 학교에 늦었어요. (I was late for school because I woke up late.)

Nuance: Waking up late happened first, and as a result, I was late for school.

Key takeaway: Use -느라고 when you want to emphasize being occupied with one action caused you to miss out on or fail at another. Use -아/어서 for more general, sequential cause-and-effect.

이야기하느라고 못 들었어요. / 늦게 와서 못 들었어요. / 우느라고 눈이 부었어요. / 많이 울어서 눈이 부었어요.

To use -느라고 naturally, avoid these common mistakes.

Don't use with positive outcomes.

Using -느라고 for a positive result sounds awkward. The pattern implies a trade-off or a cost.

Incorrect: 열심히 공부하느라고 시험에 합격했어요. (Because I studied hard, I passed the test.)

Correct: 열심히 공부해서 시험에 합격했어요.

Don't use with adjectives (descriptive verbs).

-느라고 only attaches to action verbs.

Incorrect: 피곤하느라고 일찍 잤어요. (Because I was tired, I slept early.)

Correct: 피곤해서 일찍 잤어요.

Don't use with commands or suggestions.

You cannot use imperative (-(으)세요) or propositive (-(으)ㅂ시다, -을까요?) endings with -느라고.

Incorrect: 운전하느라고 전화 받지 마세요. (Don't answer the phone because you're driving.)

Correct: 운전하니까 전화 받지 마세요.

도와주느라고 바빴어요. / 청소하느라고 힘들었어요. / *바쁘느라고 못 갔어요. (Incorrect) -> 바빠서 못 갔어요. (Correct)

The -느라고 pattern itself does not change for politeness. The formality of your sentence is determined entirely by the verb ending in the main (second) clause.

Casual Language (반말)

Use casual endings like -아/어 for friends, family, or people younger than you.

청소하느라고 힘들었어. (I got tired from cleaning.)

웃느라고 배가 아파. (My stomach hurts from laughing.)

Polite Language (해요체)

Use polite endings like -아요/어요 for general situations, colleagues, or people you don't know well.

청소하느라고 힘들었어요. (I got tired from cleaning.)

웃느라고 배가 아파요. (My stomach hurts from laughing.)

일하느라고 못 갔어. / 일하느라고 못 갔어요. / 돈 버느라고 바빠. / 돈 버느라고 바빠요.
