Core Pattern Rule: Doing One Thing for Two Reasons
The pattern -(으)ㄹ 겸 is used to indicate that an action is performed for two or more purposes. It's similar to saying "partly to do A, and partly to do B" or "for the purpose of A as well as B."
Meaning & Usage
Meaning: It attaches to a verb to express a secondary purpose for the main action that follows. It implies you're accomplishing multiple things at once.
When to use: Use it when you want to mention an additional reason for your action. For example, you went to a café. The main reason was to meet a friend, but you also wanted to try a new coffee. You can connect these ideas with -(으)ㄹ 겸.
Formation
This pattern attaches directly to verb stems.
Vowel or ㄹ ending stem + -ㄹ 겸:
보다 (to see) → 볼 겸
만들다 (to make) → 만들 겸
Consonant ending stem + -을 겸:
먹다 (to eat) → 먹을 겸
찾다 (to find) → 찾을 겸
The particle -도 (also, too) is very frequently used with the noun before the verb to emphasize the additional purpose, as in 바람도 쐴 겸.
바람도 쐴 겸 나왔어. / 살도 뺄 겸 걸어가자. / 친구도 볼 겸 밥 먹으러 왔어.
Common Combinations: A 겸 B
While you can state one additional purpose, it's also common to list two or more purposes explicitly before stating the main action.
A-(으)ㄹ 겸 B-(으)ㄹ 겸
This structure lists two distinct purposes for a single action. It makes the multi-purpose nature of the action very clear.
Example: 한국어 공부도 할 겸 친구도 사귈 겸 한국에 왔어요. (I came to Korea to study Korean and also to make friends.)
겸사겸사 (kyum-sa-kyum-sa)
This is a very common standalone adverbial phrase derived from 겸. It means "for this and that reason" or "all in one go." You use it when you have multiple, sometimes unstated, reasons for doing something. It's a great way to sound natural and a bit vague about your full intentions.
Example: 왜 왔어? (Why did you come?) → 응, 겸사겸사. (Oh, for various reasons.)
