Hold one scallop shell in your hand. It is flat, it is round, it is two matching halves that shut together, and its edge runs in and out in a row of small curves. Almost everything this word does comes off that one object. The curved edge becomes a shape you can give to cloth and paper, and then an action — to scallop an edge. The hollow half becomes a dish, and a dish baked in it becomes a way of cooking. Only the thin slice of meat comes by a different road, out of the same old word for a shell.
From the word’s history
From Old French escalope, 'shell'; the source records it as a doublet of escalope and as related to scale and shell.
來源記載它來自古法文 escalope，意思就是「殼」，並且跟 escalope（薄肉片）是同一個字的兩條路，也跟 scale（鱗片）、shell（殼）有關。這幾個字共通的畫面都是「薄薄的一片外殼」，正好對上今天手裡那片扇貝。
