[pacerier]

ok i'll take it slowly, but learning the kanji actually makes it easier for me to remember the word because some of the meanings of the character correspond to that of chinese, which is my mother tongue.

regarding the structure of the の（ん）, does it only apply for [Adj]+の（ん） or is it usuable like this as well [Noun]+の（ん）: それはパソコンのです


i grabbed this from somewhere: 彼女はいつも自分の部屋をきれいしておく
is the sentence valid? i'd thought きれい is an adjective, what does きれいしておく means?
