One way to hold this branch: a plant that arrived from far away. Above the ground, broad leaves and thick red stems; under the ground, a short brown-yellow root. The stems are sour and are cooked with sugar. The root is bitter and is dried for medicine. One plant, two parts, two uses.

這一支可以想成：一株從遠方運來的植物。地上是寬大的葉子和紅色的粗莖，地下是一截棕黃色的根。莖是酸的，加糖煮成甜點；根是苦的，曬乾當藥。同一株植物，兩個部位，兩種用途——英文都叫 rhubarb，只能靠上下文分辨。From the word’s history
The name probably comes from Greek rhêon barbarikón, the rhubarb of foreign lands, because the plant reached Europe from far away along the trade routes.
這個名字很可能來自希臘文 rhêon barbarikón，字面是「外邦的大黃」，因為它是沿著貿易路線從遠方運到歐洲的。這也解釋了為什麼「藥材」那一面比「甜點」那一面更早。

這一支可以想成：舞台後排的演員低聲反覆念著同一個字，rhubarb、rhubarb、rhubarb。子音不硬，母音不清，一群人一起念就糊成一片。這整支意思都從那個畫面長出來——聽得到，卻聽不懂。From the word’s history
This branch is traced to the London stage around 1852, where Charles Kean's company had actors repeat the word to imitate indistinct conversation; the word was chosen because it has no harsh consonants and no clear vowels.
這一支的來源記載在一八五○年代的倫敦劇場：Charles Kean 的劇團讓演員反覆念 rhubarb 來模仿聽不清的談話聲，挑這個字正是因為它沒有刺耳的子音，也沒有清楚的母音。
