A type of lettuce that has tightly packed, crunchy leaves and forms a firm head, often light green in color.
I bought a crisphead lettuce to make a fresh salad for dinner.
Crisphead is formed from "crisp" (from Old English "crisp", meaning curled or frizzy) and "head" (from Old English "heafod", meaning the top or leader). The word "crisphead" refers to a type of lettuce with tightly curled leaves that form a compact head.
Think of 'curled' ('crisp') leaves forming a 'top' ('head') — that's why crisphead refers to a type of lettuce with tightly curled leaves.
