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.)
겸사겸사 하는 거지. / 겸사겸사 하는 거죠. / 기분 전환도 할 겸 쇼핑도 할 겸 백화점에 갔어요.
Native Nuance: Stated vs. Implied Purpose
The choice of -(으)ㄹ 겸 over other 'purpose' patterns like -(으)러 or -(으)려고 adds a specific nuance. It often introduces a secondary, sometimes more socially acceptable or casual, reason for an action, while the main reason might be different or simply implied.
Softening Your Intention
인사도 할 겸 연락했어요. (I contacted you to say hello, too.)
The primary reason might be to ask for a favor, but leading with a friendly reason like "saying hello" makes the request feel less abrupt.
Justifying an Action
기분 전환도 할 겸 쇼핑했어. (I went shopping to refresh my mood as well.)
This gives a nice-sounding reason for what might just be impulsive shopping. It frames the action as serving a positive purpose.
In short, -(으)ㄹ 겸 makes your motivations sound more layered and often more casual than stating a single, direct purpose.
얼굴도 볼 겸 들렀어. / 소식도 들을 겸 만났어요. / 도와줄 겸 일찍 갔어.
Politeness & Formality
The -(으)ㄹ 겸 pattern itself is neutral. The overall politeness of your sentence is determined by the final verb ending.
The script lines provide clear examples of switching between casual and polite speech.
Casual Speech (반말)
Used with friends, family, or people younger than you. The sentence ends with forms like -어/아/었어/았어 or -자.
얼굴도 볼 겸 들렀어. (I stopped by to see your face, too.)
Polite Speech (해요체)
Used in most everyday situations with colleagues, acquaintances, or elders. The sentence ends with -어요/아요/었어요/았어요 or -아요/어요 for suggestions.
얼굴도 볼 겸 들렀어요. (I stopped by to see your face, too.)
운동도 할 겸 걸어왔어. / 운동도 할 겸 걸어왔어요. / 살도 뺄 겸 걸어가자. / 살도 뺄 겸 걸어가요.
