History

Etymology

From Middle English core, kore, coor (“apple-core, pith”), of obscure and uncertain origin. Possibly of native English origin, from Old English *cor, related to Old English *coruc, *corc (diminutive) (> Middle English cork, crok (“core of an apple or other fruit, heart of an onion”)) and Old English corn (“seed", also "grain”); or alternatively 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. Compare typologically Russian серде́чник (serdéčnik), сердцеви́на (serdcevína)) (akin to се́рдце (sérdce), cognate with heart, Latin cor).

Learned borrowing from Ancient Greek κόρη (kórē, “maiden”).

From French Coré.

See corps.

See chore.

From Biblical Hebrew כֹּר (kōr).

Possibly an acronym for cash on return.

From -core, ultimately from Etymology 1.
