-아/어 놓다: Doing Something and Leaving the Result

놓다 by itself means "put down, place, set down" — you 놓다 a cup on the table. As an auxiliary on a main verb's 아/어 form (열어 놓다, 켜 놓다, 써 놓다), it keeps that "set it down and leave it" flavor and turns it into a grammatical idea: you perform an action and leave its result standing. The spotlight is not on the action itself but on the state it leaves behind — a state you deliberately created and that now persists.

The point is the lingering result

Compare 창문을 열었어요 ("I opened the window") with 창문을 열어 놓았어요. The first just reports the act of opening. The second says: I opened it and it's now sitting open — the open state is the point. -아/어 놓다 is about producing a condition and letting it stand, ready and waiting.

That word 미리 ("in advance, ahead of time") is a frequent partner, because a huge slice of what 놓다 does is preparation: you set something up now so the result is standing there when it's needed later. 표를 사 놓다 (buy the tickets and have them ready), 예약해 놓다 (make the reservation and have it in place), 청소해 놓다 (clean and leave it clean).

Why English needs a whole clause for this

Here's the source-language gap. To translate 열어 놓았어요 faithfully, English has to spell out the persistence: "I've left it open," "it's already been done," "I opened it and it's still open." Korean packs all of that — the action, the completion, and the result standing — into one auxiliary. So attaching 놓다 rather than using plain past is a meaningful choice: it tells your listener "and that state is now in place; count on it."

The colloquial contraction is worth learning immediately, because you'll hear it far more than the full form: 놓아요 → 놔요, 놓았어요 → 놨어요.

How it differs from -아 있다 and -고 있다

Korean has several ways to talk about ongoing states, and -아/어 놓다 needs to be sorted from two neighbors covered in the aspect module.

• -고 있다 is the progressive: 창문을 열고 있어요 = "I am (in the middle of) opening the window" — the action is in progress. See -고 있다: progressive.
• -아/어 있다 is a stative result, typically with intransitive verbs, and crucially does not name an agent: 창문이 열려 있어요 = "the window is (in a state of being) open" — it just is open, no one credited. See -아/어 있다: resultant state.
• -아/어 놓다 also gives a resulting state, but it's transitive and agent-centered: you did the opening and left it that way. 창문을 열어 놨어요 = "I opened it and it's open (because I left it so)."

So the three answer different questions: 열고 있다 = what are you doing? (opening it, right now); 열려 있다 = what state is it in? (open, agentlessly); 열어 놓다 = what did you set up? (you opened it and left it open on purpose).

Here 켜 놓고 shows another common move: chaining 놓다 with 고 to say "having set up X (and left it), then Y." The AC was switched on and left running while the next thing happened.

Almost anything transitive takes it

Most transitive action verbs accept 놓다 comfortably — 열다, 켜다, 쓰다, 만들다, 사다, 준비하다, 걸다, 붙이다, and so on. The test is whether the action produces a stable result worth leaving in place. Verbs whose result vanishes instantly (like 먹다 — once eaten, there's no standing state) don't naturally take 놓다 in the preparation sense.

놓다 vs 두다: a close cousin

The auxiliary nearest to 놓다 in meaning is -아/어 두다 ("do and keep/leave"), and they're often interchangeable: 사 놓다 ≈ 사 두다. The rough intuition is that 놓다 stresses the result standing there (you set it and it's in place), while 두다 leans toward deliberately keeping it that way for later, often over a longer stretch. The two are close enough that the distinction gets its own page — see 놓다 vs 두다 and the standalone -아/어 두다.

Common Mistakes

1. Using plain past when the persisting-result nuance matters. If the point is that the state is now standing, 놓다 carries information plain past drops.

2. Confusing it with the progressive -고 있다. 열어 놓다 (opened-and-left-open) is not 열고 있다 (in the act of opening).

3. Dropping the 아/어 connective. 놓다 rides the 아/어 form — 열어 놓다, not ×열 놓다.

4. Misspelling the contraction. 놓았어요 contracts to 놨어요, not ×놨서요 or ×놧어요. The ㅎ of 놓 is what makes it 놓았 → 놨.

Key Takeaways

• -아/어 놓다 = perform an action and leave its result standing — the lingering, prepared state is the point.
• Pairs constantly with 미리 for advance preparation (사 놓다, 예약해 놓다).
• English usually needs a full clause ("I've left it open") for what Korean does in one auxiliary.
• Contrast the trio: -고 있다 (in progress) / -아 있다 (agentless state) / -아/어 놓다 (agent-created, standing state).
• Colloquial contraction 놓았어요 → 놨어요; close cousin -아/어 두다 gets its own comparison page.
