Korean -고 있다 vs -아/어 있다: Two Kinds of "Still Happening"

Both look like progressive tense, but one means an action, the other a resulting state. See the rule with real examples — try free at kdiaryai.com.

For Korean learners at beginner to intermediate level

You wrote 앉고 있어요 to say "I'm sitting." A native speaker paused — technically understandable, but 앉아 있어요 is what they'd actually say. Both look like "progressive tense" in your textbook. They're not the same thing.

The Short Answer

-고 있다 describes an action in progress — something you're actively doing right now. -아/어 있다 describes a resulting state — the action already happened, and you're now in the state it left you in.

English collapses both into "-ing." Korean keeps them separate.

The Practical Rule

Use -고 있다 when:

  • The action is ongoing, repeating, or unfinished
  • You could stop mid-action and it would still make sense
  • It's something you keep doing

밥을 먹고 있어요. — I'm eating. (the eating is happening right now)

Use -아/어 있다 when:

  • The action already finished, and its result is what continues
  • It's a state you're in, not an action you're doing
  • Verbs like 앉다, 서다, 눕다, 죽다 almost always take this form when describing "currently in that position"

의자에 앉아 있어요. — I'm sitting (in a chair). (the sitting-down already happened — you're in the resulting state)

Side by Side

문이 열고 있어요. ❌ — sounds like the door is actively opening itself, over and over 문이 열려 있어요. ✅ — The door is open. (it was opened, and now it's in that state)

저는 서고 있어요. ❌ — implies a repeated, ongoing standing-up motion 저는 서 있어요. ✅ — I'm standing. (you already stood up; now you're in that position)

This is why "sit," "stand," "lie down," and "be open/closed" are the verbs learners get wrong most — they describe states, not ongoing actions, even though English uses "-ing" for both.

Why This Matters for Writing

Diary entries are full of these — "I was sitting at a cafe," "the window was open," "she was standing outside." If you default to -고 있다 for all of them, every sentence technically parses but sounds slightly off, in a way spell-check will never flag. It's not a typo; it's a category mistake between "doing" and "being in a state" — and that distinction is exactly what disappears when you proofread your own writing, because both versions feel like they mean the same thing in your head.
