Understanding how to use ‘-다가’ in Korean grammar is essential for expressing transitions or interruptions between actions. This versatile connector helps Korean learners describe real-life situations naturally, like “while doing something” or “when something happened.” In this post, you’ll learn the meaning, structure, common mistakes, and real-life examples of how to use ‘-다가’ effectively in conversation.

1. Definition
‘다가’ connects two clauses to indicate that the first action was interrupted by the second. It often translates to “while doing…, [something else happened]” or “in the middle of…, [another action occurred]”. For example:
공부하다가 전화가 왔어요.
(I was studying when the phone rang.)
2. Form (Structure)
Verb Stem + 다가
- Rule: Remove -다 from the verb stem (e.g., 먹다 → 먹다가) and attach 다가 directly.
- Tense Compatibility: The first clause (before 다가) is typically in the plain form, while the second clause can vary in tense.
3. Meaning & Usage
1. An action is interrupted by another action.
This usage emphasizes that the first action is stopped by an external factor (e.g., a phone call, an accident).
Examples:
- 밥을 먹다가 전화를 받았어요.
(I was eating when I got a phone call.) - 영화를 보다가 잠들었어요.
(I fell asleep while watching a movie.) - 운전하다가 사고가 났어요.
(I had an accident while driving.) - 청소하다가 다쳤어요.
(I got hurt while cleaning.) - 게임을 하다가 전기가 나갔어요.
(The power went out while I was playing a game.)
2. The first action naturally transitions into the second (often unintentionally).
This usage highlights that the first action leads to the second action without intention (e.g., meeting a friend while walking).
Examples:
- 길을 걷다가 친구를 만났어요.
(I met a friend while walking down the street.) - 책을 읽다가 좋은 아이디어가 떠올랐어요.
(I got a good idea while reading a book.) - 텔레비전을 보다가 광고를 봤어요.
(I saw a commercial while watching TV.) - 운동하다가 목이 말라서 물을 마셨어요.
(I drank water because I got thirsty while exercising.) - 쇼핑하다가 예쁜 옷을 발견했어요.
(I found a pretty outfit while shopping.)
4. Key Points to Remember
- Use ‘-다가’ only with present tense stems.
- Indicates interruption or a smooth transition.
- Cannot be used if both actions are completed in sequence.
- Usually implies something unexpected happened.
- Use only one subject for both actions.

7. Common Mistakes and Tips
⚠️ Mistake 1: Using Past Tense Before ‘-다가’
Incorrect: 책을 읽었다가 잠들었어요. ❌
(I had read a book and then fell asleep.)
Correct: 책을 읽다가 잠들었어요. ✅
(I fell asleep while reading a book.)
💡 Tip: Always use the present tense stem with ‘-다가’. Past tense implies sequential actions, not interruptions.
⚠️ Mistake 2: Subject Mismatch
Incorrect: 저는 요리하다가 친구가 왔어요. ❌
(I was cooking and my friend came.)
Correct: 요리하다가 친구가 왔어요. ✅
(While cooking, my friend came.)
💡 Tip: Restructure sentences to avoid dual subjects.
Example:
- 저는 요리하다가 (제가) 전화를 받았어요. ✅
(I answered the phone while cooking.) - 저는 공부하다가 엄마가 전화했어요. ❌
→ 공부하다가 엄마한테 전화를 받았어요. ✅

Incorrect: 집에 가고 비가 왔어요. ❌
(I went home and it rained.)
Correct: 집에 가다가 비가 왔어요. ✅
(It started raining on my way home.)
💡 Tip:
- ‘-고’ → Sequential actions: 밥을 먹고 숙제했어요.
(I ate and then did homework.) - ‘-다가’ → Interrupted actions: 밥을 먹다가 전화했어요.
(I was eating when I made a call.)
⚠️ Mistake 4: Mixing ‘-다가’ with ‘-던 중에’
Incorrect: 공부하던 중에 전화가 왔어요. ❌
(I received a call while in the middle of studying.)
Correct: 공부하다가 전화가 왔어요. ✅

💡 Tip: Use ‘-다가’ for sudden interruptions, ‘-던 중에’ for ongoing actions at a specific moment.
