cauliflower (n.)[cauliflower 词源字典]: 1590s, originally cole florye, from Italian cavoli fiori "flowered cabbage," plural of cavolo "cabbage" + fiore "flower" (from Latin flora; see flora).

First element is from Latin caulis "cabbage" (originally "stem, stalk") which was borrowed into Germanic and is the source of cole in cole-slaw and of Scottish kale. The front end of the word was re-Latinized from 18c.; the back end was influenced by flower (n.). The boxer's cauliflower ear is from 1907.[cauliflower etymology, cauliflower origin, 英语词源]
