polenta n.

Old English polente, "a kind of barley meal," from Latin pollenta, polenta, literally "peeled barley," related to pollen "powder, fine flour" (see pollen), but the ultimate origin is uncertain. English later reborrowed it 19c. from Italian polenta (from the Latin word) for "porridge made of corn (maize)," a principal food in northern Italy, originally made from chestnut meal.
