折上來的那一塊布
最看得見、最好摸得到的那個用法：動作留在布上，結果就是褲腳那一折。
noun · B2
The bottom edge of a trouser leg that has been folded up on the outside, either to make the trousers shorter or because the style is meant to look that way.
褲腳的翻折
核心畫面
Start with one small movement: something is turned upward. Hold the picture of a hand taking the end of a trouser leg and folding it back up — the piece that ends up facing you is the turn-up. Now keep the same movement but change what is being turned. Turn a card up off the pack and the face that was hidden is suddenly showing. Turn-up names the thing that has come up into view: sometimes a fold of cloth, sometimes a card, sometimes an event nobody knew was there.

可以想成一個很小的動作：有東西被往上翻起來。先看褲腳：一隻手把褲管的末端往上折回去，折起來朝著你的那一塊，就是 turn-up。接著把動作留著，換一個被翻的東西。把牌從牌堆上翻起來，原本藏著的那一面就露出來了。turn-up 命名的，就是「被翻上來、因此看得見」的那個東西——有時候是一折布，有時候是一張牌，有時候是一件沒人知道會發生的事。From the word’s history
The source records turn-up as a deverbal noun formed from the phrasal verb turn up, which is why every use still carries the movement of the verb.
資料記載 turn-up 是從動詞片語 turn up 變來的名詞。這正好對上核心畫面：每一個用法裡，那個「往上翻」的動作都還在。

翻上來、被看見的東西
跟上一個家族共用同一個動作，只是被翻的東西不再是布。布翻上來，你摸得到那一折；牌或事情翻上來，你看到的是原本藏著的那一面。
