What is the difference ? Hallo :)) in Korean there are really to many ways to express yourself.!! I stuck and the expression Because. While going through my book they are introducing way to many expression to say because. -아/어/여 + 서 -(으)니까 -(으)므로 -기 때문에 (While using this are we also nominalizing??) What is the difference and when to use what. Thank you ^^

What means > 서 < Hii, I want to know what this -esoe- means in this sentence cant really figure it out: (어떤 사람이) 저기 앉아서 <담배를 피워요. Thank you

The difference between -Verb + -다가- and -Verb + -었다가- Hai, my head is gonna explode if I don´t get this. I was thinking first that one was vor present and the other for past but on the internet site there are some examples which I do not get. : 1. The connective '-다가' : On the way to / And then The ending '-다가' is attached to the Verb directly, and is used to express change or shift of action. 1.1 Verb + -다가 This ending indicates the change of one's action on one's way, that is, interruption or discontinuation of an action. 학교에 오다가 친구를 만났어요. I met my friend when I was going to school. 극장에 가다가 (다시) 왔어요. I came back again when I was going to the theater. 공부하다가 잤어요. As I was studying, I fell asleep. 교실에 들어오다가 넘어졌어요. As I was coming into the class, I fell down. 1.2 Verb + -었다가 This ending indicates the reversal or unexpected consequence after the completion of the first action. In this case, usually, `가다, 오다' are used with some other verb. 극장에 갔다가 송선생님을 만났어요. I went to the theater and met Mr. Song. 학교에 갔다가 오세요. Go to school and then come back. 그분이 어제 집에 왔다가 갔어요. He came home and left. 불을 껐다가 켜세요. Turn on the light and turn it off. 그분이 왔다(가) 갔다(가) 해요. He keeps coming and going. 불을 껐다(가) 켰다(가) 하지 마세요. Don't keep turning it on and off. (There is no past !!) Pls what is the difference between those. They did not explain it clearly. I have searched on Internet but did not find the past one. The only explain Verb+ daga. Thank you
