그래서 vs 그러니까

reason. 그러니까 result (suggestion/command)
reason. 그래서 result(suggestionX/commandX)

그러니까 and 그래서 both mean ‘therefore’ or ‘thus’, however they are very different. When we use 그래서, we cannot use suggestion and command sentence on a result sentence. If we want to suggest/command someone, we use 그러니까. For example,

비가 와요. 그래서 우산을 가지고 갈 거예요. It is raining, so I am going to take an umbrella.

비가 와요. 그러니까 우산을 가지고 가세요. It is raining, so please take an umbrella.
비가 와요. 그래서 우산을 가지고 가세요. (X)

Let’s look at more examples with -아어서 and -(으)니까 forms. If you haven’t learned these sentence endings, please click here -아/어서 and 으니까
1) -아/어/여서 can’t be used for suggesting, requesting or ordering, whereas -(으)니까 can.   For example,

  • 날씨가 좋아서 공원에 같이 가요. (X) => 날씨가 좋으니까 공원에 같이 가요. (O) : 같이 가요 => suggestion ; therefore you can’t use -아서
  • 비가 와서 우산을 가져 가세요. (X)  => 비가 오니까 우산을 가져 가세요. (O) : -(으)세요 is an imperative verb ending; therefore you can’t use -아서
    • verb endings for suggesting are ‘-는 게 어때요?’, -(으)ㄹ까요?, ‘-(으)ㅂ시다’, ‘-자’, ‘같이 -아/어/여요’ etc and verb endings for requesting or ordering are  ‘-(으)세요’, ‘-(으)십시오’ etc.

2) You can’t use the past tense in front of -아/어/여서, while you can put the past tense in front of -(으)니까.  For example,

  • 어제 공부 많이 했어서 피곤해요. (X)    => 어제 공부 많이 해서 피곤해요. (O)
  • 어제 제가 이 영화를 봤으니까 오늘은 다른 영화를 봅시다. (O)

3) often used for general statements or emotion verbs=> -아/어/여서. For example,

  • 만나서 반갑습니다.  Glad to meet you! ( I am happy because I meet you.)
    도와 주셔서 감사합니다.  Thanks for your help! (I appreciate because you helped me.)
  • 늦어서 죄송합니다.  Sorry for being late. ( I am sorry because I am late.)
  • 배가 아파서 학교에 안 갔어요. ( I didn’t go to school because my stomach hurt.)
