위의/위에 and 입니다/습니다 difference+plural form Hello, I've been learning Korean for some months and lately I started learning from Rosetta Stone and somethings made me confused so much. I have a few questions: 1. R.Stone teaches "a child on/under/in a plane" as "비행이 위의/아래의/안의 아이", "의" pronounced as itself. However on the other sites like TTMIK, it's "위에/아래에/안에". Which is the right one? Plus,I translated 위의/아래의/안의 on Naver and the particle "의" pronounced "에". 2. I actually know the difference between 입니다 and 습니다 but I noticed that colour names like red,blue yellow takes 습니다 but pink takes 입니다? :I :I (자동차가 노랗습니다 / 자동차가 분홍색입니다) 3. I know the plural form is 들 and Rosetta stone teaches the same but there is an example made me confused. A picture of an eye is described as "한쪽 눈" and 2 eyes as "두 눈". They are translated as "eye" and "eyes" in English. Shouldn't it be "눈" and "눈들"? Thank you so much !!
