Pronunciation

  • IPA (Classical): [miː.lɪˈtaː.ri.ʊs][1]
  • IPA (Ecclesiastical): [mi.liˈtaː.ri.us][1]

Forms

mīlitārius (feminine mīlitāria, neuter mīlitārium, adverb mīlitāriē); first/second-declension adjective[1]

Etymology

It is from Latin mīles (“soldier”) + -ārius.[2][1] De Vaan finds the first part of ⟨mīles⟩ unclear and tentatively connects it with ⟨mīlia⟩ “thousands”.[3]

Earliest recorded meaning

Its source is Plautus' Pseudolus, gradus mīlitārius “a soldierly step”.[4][5][6] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

Ante-classical, it meant soldierlike, military, the same as mīlitāris.[2][4][5] The TLL considers other apparent examples, in Tacitus and Pliny the Younger, to be corruptions or false readings.[7]

Timeline

  • c. 250–184 BC – Plautus uses it.[4][6]
