core

core: [14] The origins of core are a mystery, over which etymologists disagree. Several candidates have been put forward, including Old French cor ‘horn’, on the grounds that two of core’s earliest applications were to the horny central part of apples and pears and to corns on the foot, and Latin cor ‘heart’, on the grounds that an apple’s core is its ‘heart’.

core (n.)

late 14c., probably from Old French coeur "core of fruit, heart of lettuce," literally "heart," from Latin cor "heart," from PIE root *kerd- (1) "heart" (see heart (n.)). Nuclear reactor sense is from 1949.

core (v.)

mid-15c., from core (n.). Related: Cored; coring.
