I have been self-teaching myself Korean and today I learned the adjectives this and that. I practiced making some sentences using these adjectives. These are what I came up with:
저는 이 샌드위치를 먹고 싶어요. - I want to eat this sandwich.
저는 저것 모자를 사고 싶어요. - I want to buy that hat over there.
So I asked someone for help and they gave me the correction for the second sentence. This is what they gave me:
(저는) 저기에 있는 모자를 사고 싶어요
So I wanted to clarify why 있는 had to be used. And also can you tell me if the first sentence is correct also?
