[Korean Grammar 한국어 문법] - 다가

한국어 문법 : - 다가 / 🇰🇷 Korean Grammar: –다가

( 어떤 행위가 중단되고 다른 행위로 바뀔 때 쓰임 /  Stopping one action and changing to another)

✅ Easy English Explanation

–다가 is used when:

You were doing Action A,
but you stopped and then did Action B.

So the first action does not finish. Something changes in the middle.

Think of it like:

“I was doing A, and then (something happened / I changed to B)”

 

–다가는 어떤 행동을 하던 중에
👉 그 행동이 끝나지 않고 멈춘 뒤
👉 다른 행동이나 사건이 이어질 때 사용해요.

보통 갑작스러운 일, 예상 못 한 상황, 또는 중간에 바뀐 상황을 말할 때 많이 써요.

🚨 Important Feeling of –다가

It often shows:

• An unexpected event
• A sudden change
• Something that happens in the middle of another action

---

❌ Not used for finished actions

If Action A is completely finished, we don’t use –다가.

Wrong idea:
“I ate and then I slept.” (Both actions finished normally)

That situation uses –고, NOT –다가.

✔ 하던 중에 다른 행동으로 바뀜
