Etymology 1

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.

Etymology

From Vulgar Latin *corem m, from Latin cor n.

The Logudorese form reflects the replacement of earlier /-e/ with an echo vowel based on the /o/ of the preceding syllable. (Final echo vowels are common across Sardinian dialects.) The Campidanese form reflects, in addition to that, the dialect's general merger of final unstressed /o/ into /u/.
