Doing Two Things at Once: -(으)면서
Learn Doing Two Things at Once: -(으)면서 with form rules, natural examples, common mistakes, romanization, and six practice questions with answers.
Introduction / Review
Use -(으)면서 when one person performs two actions at the same time. One action often provides the background while the other is the main activity.
N = noun; V = action verb; A = descriptive verb. Romanization is a reading aid.
Today’s Grammar / Explanation
- Vowel or final ㄹ + 면서: 가다 → 가면서; 만들다 → 만들면서. Other consonants + 으면서: 먹다 → 먹으면서.
- Irregulars: 듣다 → 들으면서; 걷다 → 걸으면서. The ㄹ of these changed forms remains.
- In the simultaneous-action use taught here, both clauses normally share a subject. Put tense on the final predicate: 들으면서 공부했어요.
Examples
음악을 들으면서 공부해요.
eumageul deureumyeonseo gongbuhaeyo
I study while listening to music.
커피를 마시면서 책을 읽어요.
keopireul masimyeonseo chaegeul ilgeoyo
I read while drinking coffee.
친구와 걸으면서 이야기해요.
chinguwa georeumyeonseo iyagihaeyo

Look ahead: Lesson 67 →| Pattern | Same subject? | Meaning | Example |
|---|---|---|---|
| -(으)면서 | Yes | at the same time | 걸으면서 전화해요 |
| -는 동안 | Not necessarily | during | 제가 자는 동안 비가 왔어요 |
| -고 | Usually | one after another | 씻고 자요 |
| -다가 | Yes | interrupted, switched | 걷다가 넘어졌어요 |
Common mistakes
If one person cooks while another cleans, -는 동안 is the clear beginner pattern. -(으)면서 has additional contrastive uses, but today’s practice is about simultaneous actions by the same person.
ㄷ-irregular: 듣다 → 들으면서.
-(으)면서 needs the same subject. For two people, use -는 동안.
No past tense before -(으)면서. The last verb shows the time.
ㄹ-stems add 면서 directly: 놀면서.
