매튜의 한국어 연습 블로그

I like this grammar point and kind of wish English had something similar. <동사>는 길 is the equivalent of "On my way to I'll " Between Point A and point B there's an easy-to-access Point C that is no problem to drop by. Any example would be a spouse calling the other and asking to:
"Buy some milk on your way home" 
집에 가는 길에 우유를 사주세요. 


To complete the sentence structure of "picking up something on the way" or "dropping by somewhere" we need a new verb that is hard for me to pronounce. The verb to drop by something on one's way is 들르다, as in "집에 가는 길에 우체국에 들러서 우표를 사주세요" (Pick up some stamps at the post office on your way home).

More examples:

A: 지금 어딘데? Where are you?
B: 집에 가는 길이야. 왜? I'm on my way home. Why?
