Etymology

It is inherited from Middle English enemi,[2][3] borrowed from Old French enemi (“enemy, adversary, foe; demon, the Devil”) (modern French ennemi), earlier inimi,[4][3] from Latin inimīcus (“an enemy”), literally “an unfriend”, a noun use of the adjective “hostile”,[4] from in- (“not”) and amīcus (“friend”),[4][5][6] which is related to amāre (“to love”).[4] Italian nemico and Spanish enemigo have the same source.[4] It is related to inimical, amicable and amiable.[6][2]

Earliest recorded meaning

Semantic evolution

From about 1300 it meant an adversary of God, an unbeliever; in the late 14th century it also meant the Devil, and a member of an armed hostile force in a war or feud;[4] of the opposing military forces as a whole it is from about 1600.[4] The adjective is from the mid-14th century.[4] Something that works against something else, as an enemy of good health, is from 1398.[7] Nobody's enemy but one's own is from 1592,[7] and death as the last enemy, after 1 Corinthians, from 1885.[7] In Scots and Shropshire dialect, the enemy was a name for the Devil.[8]
