Because of [Unexpected]

This pattern, -는 바람에, is used to connect a cause to its result, similar to "because of..." or "as a result of...". However, it has a very specific nuance.

Meaning & Usage

Meaning: It indicates that an unexpected, often sudden event (the clause before -는 바람에) directly caused an undesirable or negative outcome (the clause after).

When to use: It's most commonly used to give excuses or explain why something went wrong. The cause is typically something outside the speaker's direct control.

Formation

This pattern attaches directly to the stem of an action verb in the present tense form.

Verb stem + -는 바람에

자다 (to sleep) → 자는 바람에

오다 (to come) → 오는 바람에

놓치다 (to miss) → 놓치는 바람에

서두르다 (to hurry) → 서두르는 바람에

늦잠 자는 바람에 지각했어. / 비가 오는 바람에 취소됐어. / 서두르는 바람에 지갑을 두고 왔어.

While both -는 바람에 and -아/어서 can translate to "because," they have different nuances and are not interchangeable.

-는 바람에

Nuance: The cause is an unexpected event that leads to a negative result. It's the classic grammar for making an excuse.

Example: 버스를 놓치는 바람에 늦었어요. (Because I [unexpectedly] missed the bus, I was late.)

-아/어서

Nuance: This is a general and neutral reason. It shows a logical, direct link between cause and effect, which can be positive, negative, or neutral.

Example: 버스를 놓쳐서 늦었어요. (Because I missed the bus, I was late.) This is also correct, but it sounds more like a simple statement of fact than an excuse for an unfortunate event.

Key Difference: You cannot use -는 바람에 for positive outcomes. For instance, *날씨가 좋은 바람에 소풍 갔어요 is incorrect. You must use 날씨가 좋아서 소풍 갔어요.

커피를 쏟는 바람에 옷을 버렸어. / 휴대폰을 떨어뜨리는 바람에 액정이 깨졌어. / 감기 걸리는 바람에 못 갔어.

To use -는 바람에 naturally, keep these two critical constraints in mind.

Negative Results Only

This is the most important rule. The clause that follows -는 바람에 must describe a negative, unintended, or problematic outcome. It cannot be used for positive or neutral results.

Correct: 계획이 바뀌는 바람에 헷갈려요. (I'm confused because the plans changed.)

Incorrect: *열심히 공부하는 바람에 시험에 합격했어요. (Studying hard is intentional and the result is positive. Use 열심히 공부해서... instead.)

No Commands or Suggestions

Because this pattern explains a past event or a resulting state, you cannot use it with imperative (-(으)세요) or propositive (-자/-(으)ㅂ시다) endings.

Correct: 비가 오는 바람에 경기가 취소됐어요. (The game was canceled because it rained.)

Incorrect: *비가 오는 바람에 우산을 쓰세요. (Use 비가 오니까 우산을 쓰세요. instead.)

알람이 울리는 바람에 깼어. / 계획이 바뀌는 바람에 헷갈려요. / 물이 쏟아지는 바람에 다 젖었어.

The pattern -는 바람에 itself does not change for politeness. The formality of your sentence is determined by the final verb ending.

Casual Language (반말)

Use casual endings like -했어, -됐어, or -잖아 when speaking to close friends, family, or people younger than you.

Example: 넘어지는 바람에 다쳤어. (I got hurt because I fell.)

Polite Language (해요체)

Use standard polite endings like -했어요, -됐어요, or -잖아요 in most everyday situations with colleagues, acquaintances, or elders.

Example: 넘어지는 바람에 다쳤어요. (I got hurt because I fell.)

Notice how only the final verb changes, not the -는 바람에 part.

차가 막히는 바람에 늦었어. / 차가 막히는 바람에 늦었어요. / 네가 떠드는 바람에 놓쳤잖아. / 호리 씨가 떠드는 바람에 놓쳤잖아요.
