垂褶的布
核心畫面

可以想成：一塊布被放開，順著自己的重量垂下來，自然堆出一道一道的褶。沒有拉平，也沒有繃緊，就是往下掛著。drapery 的每個意思都圍著這塊布轉：垂下來的樣子、掛在窗前那幾片厚布、還有店裡一匹一匹拿去賣的布。From the word’s history
The word comes through Middle English draperie from Old French draperie, built on drap, which simply means cloth. The root is the cloth itself, which is why the word can point at how cloth hangs and at cloth as goods.
這個字經過中古英文 draperie，來自古法文 draperie，字根 drap 就是「布」。因為根就是布本身，所以這個字既能講布垂下來的樣子，也能講當成商品的布。
