your post Dr bill, made me think of cowl- a hood, especialy on a monks robe, or a type of neckline on a womans garment..
cowl, according to Bartleby's, comes from
Middle English coule, from Old English cugele, from Late Latin cuculla, from Latin cucullus, hood. --

you'd think it would come from a word for head!

weird isn't it how cape (which doesn't cover your head) come from the latin root word for head, but cowl, which does cover you head doesn't?
