Quoted from http://www.talktomeinkorean.com/lessons/l6l14/ 겸 When you want to say “breakfast/lunch” or “singer/actor”, you use the word 겸. Examples 1. 아침 겸 점심 = breakfast/lunch, brunch 2. 가수 겸 배우 = singer and actor, singer/actor 3. 화가 겸 작곡가 = painter/composer, painter and composer -(으)ㄹ 겸 When you want to talk about an action that has two or more purposes, you can list them using -(으)ㄹ 겸. When you just mention one purpose using -(으)ㄹ 겸 in a sentence, the other purpose has to be understood from the context. And since -(으)ㄹ 겸 usually has the nuance of “both at the same time”, you often use the particle -도 (meaning “also”) after the noun that comes before “Verb + -(으)ㄹ 겸”. Examples 1. 바람 좀 쐴 겸 밖에 나왔어요. = (There’s another reason/purpose, too, but) I came outside to get some fresh air. 2. 영어 공부도 할 겸, 영어로 된 소설을 읽고 있어요. = (I’m doing it because it’s fun, too, but) I’m reading a novel written in English to study English as well. 3. 친구 생일 선물도 살 겸, 제 옷도 볼 겸, 백화점에 갈 거예요. = I’m going to go to the department store to buy a present for my friend’s birthday and, at the same time, look at some clothes for myself. 4. 산책도 할 겸, 사진도 찍을 겸, 남산에 갔어요. = I went to Namsan to take a walk and also to take some photos.
