cole
Word family
Synonym discussion
Sense: noun/1
Cole, brassica, cabbage, and kale all point to plants in the mustard family, but they operate at different levels of precision. Cole is an old word for any leafy brassica grown for food — it is the broadest and most old-fashioned of the four. Brassica is the modern scientific genus name and sounds technical; you would use it in a botany paper, not at the dinner table. Cabbage refers specifically to the tight-headed variety, the round pale-green vegetable found in every supermarket. Kale is a particular brassica with loose, curly leaves that has become popular as a health food. So if a sixteenth-century farmer said 'cole,' he might have meant kale, cabbage, or any leafy green in between — but today a shopper who wants kale will not ask for cole.
Etymology
Cole comes from Old English cāl or cāwel, which was borrowed from Latin caulis meaning 'stem' or 'cabbage.' It is the same root that gave us kale (a northern English form), cauliflower, and kohlrabi. For centuries cole was the ordinary English word for cabbage; it only fell out of everyday use in the 1700s, surviving in compounds like coleslaw (from Dutch koolsla, 'cabbage salad') and colewort.
