可以想成：ruffle 的畫面比較像「把平順的表面推出一道一道小皺褶」。手在梳好的頭髮上一撥，風在靜止的水面上一吹，本來平的就變成一波一波。有時候這些皺褶馬上就散掉了。有時候它們被縫住、固定下來，就成了衣服邊上的荷葉邊。連心情也可以這樣看：本來平靜，被一句話撥一下，就起了小波紋。From the word’s history
The supplied source traces ruffle to Middle English ruffelen, perhaps from Old Norse hrufla, to graze or scratch, or Middle Low German ruffelen, to wrinkle or curl, and links it to English ruff. The source itself says the further origin is unknown, so this is a possible route, not a settled one.
手上的來源說 ruffle 來自中古英文 ruffelen，可能跟古北歐語 hrufla（擦、刮）或中古低地德語 ruffelen（起皺、捲）有關，並且跟英文的 ruff（皺領）同一家。來源自己也說再往前就不清楚了，所以這只是一條可能的線，不是定論。
