Pronunciation[edit]

Etymology 1[edit]

From Middle English core, kore, coor (“apple-core, pith”), of uncertain origin. Possibly of native English origin (compare Old English corn (“seed", also "grain”), or perhaps from Old French cuer (“heart”), from Latin cor (“heart”); or from Old French cors (“body”), from Latin corpus (“body”). Compare also Middle English colk, coke, coll (“the heart or centre of an apple or onion, core”), Dutch kern (“core”), German Kern (“core”). See also heart, corpse.
