Forms

inimigo m (plural inimigos, feminine inimiga, feminine plural inimigas)[1] The medieval language had many forms: ẽemigo, eemigo, emigo, enemigo, enmijgo, imigo, iimigo, ymigo and inimigo.[2][3][4] Imigo was still usual in the 16th century: a letter of 1561 has Imigos.[5]

Etymology

It is inherited from Latin inimīcus (“unfriendly; enemy”), whose regular outcome in the oldest texts is Old Galician-Portuguese ẽemigo.[2][1] The modern form was refashioned on the Latin word, a semi-learned form that replaced the popular ones.[6][7][1]

The same Latin word is Spanish enemigo, Catalan enemic, French ennemi and Italian nemico.[8][1] García de Diego gives the old Portuguese forms Old Galician-Portuguese eimigo and Old Galician-Portuguese iimigo beside the old Galician one.[9]

The Latin word is made of in- (“not”) and amīcus (“friend”).[4][1] The DHLF notes that it first meant a personal enemy, as opposed to hostis (“public enemy”), and that in Christian Latin it also named the Devil.[8]

Earliest recorded meaning

The Cantigas de Santa Maria speak of seu ẽemigo “his enemy” and of en poder do ẽemigo “in the power of the enemy”.[2] A legal text of 1209 printed among the Portugaliae Monumenta Historica already has meu inimigo he “he is my enemy”.[10]

Semantic evolution

The medieval texts use the word for a personal or military enemy, the enemies of the faith (aos enmijgos da nossa fe, 1317) and, as in Latin, the Devil (o demo que he sempre eemigo dos homẽs “the devil, who is ever the enemy of men”).[2] The sense “the Devil” survives in informal speech.[4][11]

Houaiss's first date, 1188–1230, is for the feminine form nimjga.[4] The word is both an adjective, “hostile; belonging to the opposing side” (tropas inimigas), and a noun;[4][12] Vieira quotes Diogo do Couto's Décadas for the enemy in war (a Armada inimiga).[4][12] A thing can also be the enemy of another: a pressa é inimiga da perfeição “haste is the enemy of perfection”.[4]

Timeline

  • 1188–1230 – nimjga, the first date Houaiss gives.[4]
  • 1209 – inimigo and enemigo in a legal text in the Portugaliae Monumenta Historica.[10]
  • 13th century – ẽemigo in the Cantigas de Santa Maria.[2][3]
  • 1317 – aos enmijgos da nossa fe in a document.[2]

  • 1755 – Folqman glosses Inimigo with Latin inimicus and, for an enemy in war, hostis.[13]
