Pronunciation

  • IPA (Classical): [miː.lɪˈtaː.rɪs][1]
  • IPA (Ecclesiastical): [mi.liˈtaː.ris][1]

Forms

mīlitāris (neuter mīlitāre, adverb mīlitāriter); third-declension two-termination adjective[1]

Etymology

It is from Latin mīles (“soldier”) + -āris.[2][1] De Vaan finds the first part of mīles unclear, though it is tempting to connect it with mīlia “thousands”, as one who goes with a thousand.[3]

Earliest recorded meaning

Plautus speaks of militaris disciplina, military discipline, and of officers' sons as militares pueri.[2][4]

Semantic evolution

It meant of the army, its customs and activities, as Cicero's military laws and Caesar's res militaris “the art of war”.[2][5] Of age it meant fit for service, as Sallust's “you who are of military age”, and of persons serving and experienced, as Sallust's homo militaris, a seasoned soldier.[2][5]

As a noun it meant a soldier, in Curtius.[6] In medieval Latin it meant knightly, homo militaris a knight, militaris ordo knighthood, and a knight's fief.[7][1] English military was borrowed in the mid-15th century.[8]
