Learn Hardcore Korean: geosil byeoge geurimeul georeo nohasseoyo. - I hung a picture on the living room wall.

거실 벽에 literally means “on the living room wall.” The particle 에 marks a specific location where an action takes place or where something exists. Without 에, you wouldn’t indicate the correct locative meaning.

Why is 그림을 marked with the particle 을?

그림 is the direct object of the verb 걸다 (“to hang”), so it takes the object marker 을. This shows that the picture is what’s being hung.

What’s the nuance of 걸어 놓았어요 compared to simply 걸었어요?

걸어 놓았어요 uses the construction -아/어 놓다, which emphasizes that the action was completed and its result remains (the picture is now hanging and stays that way). 걸었어요 just states the past action of hanging, without highlighting the continued result.

Can you explain how the grammar pattern -아/어 놓다 works?

Attach -아/어 to a verb stem, then add 놓다. It conveys:

The action was done deliberately,
The resulting state is kept.
In this sentence, 걸어 놓았어요 means “I hung it up (and left it hanging).”

Why is there no subject in this sentence?

Korean often drops the subject when it’s clear from context. Here, “I” is implied, so there’s no need to say 제가. If you wanted to specify, you could say 제가 거실 벽에 그림을 걸어 놓았어요.

Could I use 걸어 두었어요 instead of 걸어 놓았어요?

Yes. 걸어 두었어요 (using 두다 instead of 놓다) carries almost the same meaning—“hung something up and left it there.” Both 놓다 and 두다 express leaving the result of an action in place.

Are there other verbs for “to hang” in Korean?

매달다: to suspend or hang (often used for decorations or plants).
걸다: most common for pictures, clocks, coats, etc.
붙이다: to attach or stick (use when you tape or glue something to the wall rather than hanging it).
