Omit postpositions in a sentence
Korean grammar shows many kind of postpositions to make sentence.
은,는,이,가,를,을,에,로,도,랑... these help to make clear subject or ob-ject in sentence but Koreans often omit them in common to make sentence shortly and naturally.
For example :
- 나는 책을 읽어. -> Without postposition : (나) 책 읽어.
- 너는 어디에/로 가? -> Without postposition : (너) 어디 가?
- 너는 밥을 먹었어? -> Without postposition : (너) 밥 먹었어?
We can omit postposition as usual but always there are exceptions.
When we don't have to omit it.
1. when we use 니/네(you) ~가 : 니가 해! (O), 니 해!(X)
2. When it means any conjunctions as and, then.. : ~랑, ~도, ~서... - 나랑 너랑, 나도 너도, 밥을 먹어서...
3. When we answer where we are going : 나 집에 가(O), 나 집 가(X)
4. When we emphasize someone/someting ~만 : 너만 그래! only you do so.
