Verb + 러 간다
Let’s take a look at the pattern Verb + 러 간다. We have actually learned this before but we’re going to focus on the nuance of 가다 when conjugated into –ㄴ다 form as in 간다. We attach (으)러 to stem of a verb to express the purpose of going or coming. It is similar to the English phrase I am going to the market (to buy fish). The part to buy fish is (으)러. We say 간다 to express that we’re going to leave someone for now or for a while to do something. For example, you are watching TV with your brother and you suddenly feel sleepy. So you would leave him to go to bed and take a nap. It’s a good way to let someone know the purpose of your leaving.
난 자러 간다.
I am going to bed.
밥 먹으러 간다.
I am going to eat.
I’ll leave you here for now. I’m going to the gym.
Bye for now. I’ve got to study.
I’ve got to take a shower. Will be back.
