Nouns modified by の? I'm currently learning about adjectives in Japanese and have come to realize that there are two general kinds: there are adjectives made by modifying verbs (い-adjectives), and adjectives made by modifying nouns (な-adjectives). My question is this: I have seen people use の in place of な and was wondering if this is another subcategory of adjective. I've seen nouns classified as の- adjectives; does this mean they must be followed by の? Or, since they're nouns, can they be followed by な as well? Hopefully this isn't too complex of a question. Example: 紫色の葉 vs. 紫色な葉 or 緑の家 vs. 緑な家 どちは合います？よろしく！
