英語の語源
entire
entire: [14] Entire and integrity [15] have the same source – Latin integer. This meant ‘whole, complete’, and was formed from the prefix in- ‘in’ and *tag-, the base which produced Latin tangere ‘touch’, source of English tactile and tangible (and indeed of intact [15], a parallel formation to entire and integrity).
English borrowed integer [16] itself as a mathematical term denoting a ‘whole’ number, and several of its Latin derivatives – not just integrity but also integral [16], from late Latin integrālis, and integrate [17], from Latin integrāre ‘make whole’. As its difference in form suggests, however, entire came via a different route.
The Latin accusative form integrum produced Vulgar Latin *integro, which passed into Old French as entier – hence English entire. => intact, integrity, tactile, tangible
entire (adj.)
late 14c., from Old French entier "whole, unbroken, intact, complete," from Latin integrum "completeness" (nominative integer; see integer). Related: Entireness.
