使變白；把顏色褪掉
核心畫面
One picture holds this word together: colour draining out of something until what is left is white. Sun pulls it out of cloth, years pull it out of hair, soil over a stem keeps it from ever arriving. Boiling water does it to the surface of an almond or a piece of meat, which is how the cooking sense got the name. And does it to a face, when the blood leaves and the person goes white in a second. In every case, something has gone out of the thing, and the paleness is what you see.

這個字可以用一個畫面串起來：顏色從東西裡退掉，剩下白。太陽把布上的顏色曬掉，歲月把頭髮的顏色帶走，堆在莖上的土則讓顏色一開始就進不來。滾水也做同樣的事，杏仁和肉的表面一燙就泛白，廚房裡的用法就是這樣得名的。受驚嚇的臉也一樣，血色一退，人一下子就白了。每一次都是有什麼東西離開了，而你看到的就是那片白。From the word’s history
Wiktionary traces this verb through Middle English blaunchen and Old French blanchir to blanc, meaning white. The word started out meaning simply to make white, which is why the cooking sense, the garden sense and the frightened face all sit under one picture. Wiktionary also records a second, separate blanch, a variant of blench meaning to evade or turn aside; that is a different route and none of the senses written here belong to it.
依 Wiktionary，這個動詞經中古英語 blaunchen、古法文 blanchir，回到 blanc（白）。它一開始的意思就只是「使變白」，所以廚房裡的汆燙、園藝的遮光、驚嚇時的臉色發白，才能共用同一個畫面。另外 Wiktionary 還記了一個同形但不同源的 blanch，是 blench 的變體，意思是「閃避、迴避」。那是另一條路線，這裡寫的三個意思都不屬於它。
