Pronunciation

  • Classical: [ɪnˈwɪk.tʊs][1]
  • Ecclesiastical: [iɱˈvik.tus][1]

Forms

invictus (feminine invicta, neuter invictum, superlative invictissimus); first/second-declension adjective[1]

Etymology

It is formed from Latin in- (“not”) + victus (“conquered”), the second part being the participle of vincō (“to conquer”).[2][1] De Vaan traces ⟨vincō⟩ to Proto-Italic *wink- (“to tie, bind, overcome”) and Proto-Indo-European *wi-n-k- (“to bend, tie”), cognate with Old Irish fichid (“fights”).[3]

Earliest recorded meaning

Ennius addresses Scipio as Scīpiō invicte, “unconquerable Scipio”.[2]

Semantic evolution

It means unconquered, undefeated in war, as Cicero's Roman people whose name stayed unbeaten at sea, and in games and contests.[2] It also means invincible, and as a title of gods, and later of the emperor, “the Invincible”: Accius already invokes a god as invicte.[2] It is used of those not overcome by hardship and of indestructible matter (Lucretius' atoms flying unconquered through time), and of a resolute mind, which Cicero says must look down on human affairs.[2] Lewis & Short note its many constructions: with ab, ad, contrā, adversum and the ablative or genitive.[4]

Church Latin glosses it “unconquerable, invincible, unsubdued”.[5]
