Etymology: "Oppilation" comes from Latin "oppilatio," a noun built on "oppilare," meaning to stop up or block, from "ob" (against, in the way) and "pilare" (to press, to ram, from "pila," a pillar or pile). The image is literal: something rammed or piled in front of a passage. English took the word with the same sense, so it has always described an obstruction of a channel rather than anything abstract. French preserved a parallel form, "opilation," which carries the same medical and physical sense. The English word is best understood as a learned borrowing that followed the Latin and French route, and it has stayed a specialist term, used mainly in medical writing about blocked ducts, vessels, or passages in the body.
