Why are collard greens called collard greens?

Collard greens are named after the Word "colewort," which refers to the wild cabbage plant from which they descend. The term "cole" is derived from the Latin "caulis," meaning "stem" or "cabbage," while "wort" refers to a plant or herb. Over time, "colewort" evolved into "collard," specifically designating this leafy green vegetable. Their name reflects their close relationship to other members of the Brassica family, such as cabbage and kale.
