Questions & Answers about bakkeseo keun soriga naseo gongbureul banghaehaeyo.

Why does it use 밖에서 and not 밖에?

밖에서 marks the location where the sound originates/occurs: 밖에서 큰 소리가 나다 = a loud sound happens/comes from outside.
밖에 usually means outside (as a place you’re at/going to) or appears in patterns like 밖에 없다 (there’s only…). For “a sound occurs outside,” -에서 is the natural choice.


What does 소리가 나다 literally mean, and why not 소리를 내다?
  • 소리가 나다 = a sound comes out / is heard (the sound “happens” on its own; focus on the sound occurring).
  • 소리를 내다 = to make a sound (someone actively produces it).

Here the sentence focuses on the fact that a loud noise occurred outside, not on who intentionally made it, so 소리가 나서 is appropriate.


What is -아서/어서 doing in 나서?

나서 is 나다 + -아서/어서, meaning “because/since (a sound) occurs” or “and then” depending on context.
In this sentence it functions as a cause: 큰 소리가 나서 … = Because a loud sound happened…


Can -아/어서 here mean “and then” instead of “because”?

In theory -아/어서 can connect events (“do A and then B”), but with 방해해요 (it interferes), the natural reading is causal: loud noise → it disrupts studying. So most listeners will interpret it as because/since.


Why is 공부를 marked with -를? Isn’t studying the thing being interrupted?

Yes—공부를 is the direct object of 방해하다 (to interrupt/obstruct).
Structure: (큰 소리가) 공부를 방해해요 = The loud noise interferes with studying.


How is 방해해요 formed? What verb is it from?

It comes from the verb 방해하다 (to interfere with, to disturb).
방해하다 → 방해해요 is the present polite style. Many 하다-verbs contract like this:

  • 방해하여요 → 방해해요
  • similarly: 공부하다 → 공부해요

Who/what is the subject of 방해해요? It isn’t explicitly marked.

The implied subject is 큰 소리(가) = “the loud noise.” Korean often omits subject markers when context is clear. Expanded version:

  • 밖에서 큰 소리가 나서 (큰 소리가) 공부를 방해해요.

Why is there no -가/이 after 큰 소리? Shouldn’t it be 큰 소리가 나서?

Both are possible, but 큰 소리가 나서 is more explicit and very common.
Omitting -가 here is casual/natural in speech and writing when the subject is obvious. Adding it makes the sentence a bit clearer for learners:

  • 밖에서 큰 소리가 나서… (with )
  • 밖에서 큰 소리 나서… (without , more colloquial)

Is 큰 소리 “a loud sound” or “loud sounds”? Why no plural?

Korean nouns typically don’t mark plural unless needed. 큰 소리 can mean:

  • a loud noise (one event), or
  • loud noises (repeated/ongoing), depending on context.

If you want to emphasize repeated noises, you could say things like 큰 소리가 계속 나서 (because loud noises keep happening).


What nuance does 밖에서 add compared to 밖에 or 밖으로?
  • 밖에서: at/from outside (location where the sound occurs)
  • 밖에: outside (often destination/location, or “only” pattern)
  • 밖으로: toward/out to the outside (direction/movement)

Since there’s no movement, 밖으로 would be wrong here.


Is 공부를 방해해요 the same as 공부에 방해가 돼요?

They’re similar but not identical:

  • 공부를 방해해요: active verb, “(something) interferes with studying.”
  • 공부에 방해가 돼요: “It becomes an obstacle to studying,” slightly more indirect/description-focused.

Both are natural; 방해해요 is straightforward and common.


Can I replace 방해해요 with 방해돼요?

Yes, 방해돼요 (from 방해되다) means “to be disturbed/interfered with,” focusing on the affected side:

  • 큰 소리 때문에 공부가 방해돼요. = Because of the noise, my studying gets interrupted.

In your sentence, 방해해요 frames the noise as the actor causing the interference.


Why is there no explicit word for “my” in “it interrupts my studying”?

Korean often omits possessives when obvious. 공부를 방해해요 naturally implies “(my/our) studying” in context. If you want to specify:

  • 제 공부를 방해해요 = It disrupts my studying.
  • 공부하는 걸 방해해요 = It disrupts (me) studying.

What’s the role of ? Is it an adjective?

is the attributive (noun-modifying) form of the descriptive verb 크다 (to be big/large).
So 큰 소리 literally means a big sounda loud noise.


Is 소리 always “sound,” or can it be “noise”?

소리 is broadly “sound,” but in context it can mean “noise,” especially with or when it’s disturbing:

  • 큰 소리 often translates naturally as loud noise.

How would I make it more natural to emphasize that the noise is continuous?

Add an adverb like 계속 or 자꾸:

  • 밖에서 큰 소리가 계속 나서 공부를 방해해요. = Because loud noises keep happening outside, it interferes with studying.
  • 밖에서 큰 소리가 자꾸 나서… = Because there’s repeatedly loud noise outside…

Can this sentence describe a one-time loud bang, like a door slam?

Yes. With no extra context, it can refer to either:

  • a single event (a loud bang), or
  • repeated loud sounds.

If you want to make “one-time” clearer, you can add something like 갑자기 (suddenly):

  • 밖에서 갑자기 큰 소리가 나서 공부를 방해해요.

Is the tense correct? Why present 방해해요 instead of past 방해했어요?

방해해요 can describe a current/general situation: “It’s interfering (right now).”
If you’re talking about a completed past event, use past:

  • 밖에서 큰 소리가 나서 공부를 방해했어요. = A loud noise happened outside, so it disrupted my studying.
