SIMULTANEOUS ACTIONS WITH -으면서
In Korean, the grammar structure -(으)면서 is used to indicate that two actions occur at the same time. It is equivalent to “while” in English.
This structure is useful for describing actions that happen simultaneously, whether they are performed by the same subject or within the same time frame.

INTRODUCTION OF -(으)면서
The structure -(으)면서 is attached to the verb stem and follows these rules:
- If the verb stem ends in a vowel → Attach -면서
- Example: 가다 (to go) → 가면서 (while going)
- If the verb stem ends in a consonant → Attach -으면서
- Example: 먹다 (to eat) → 먹으면서 (while eating)
PATTERN
Verb stem + -(으)면서
Exceptions
- The structure cannot be used with adjectives. Instead, -고 or -게 structures are preferred.
- Example: 행복하면서 (incorrect) → 행복하고 (correct) (while being happy)
HOW TO USE -(으)면서
