Pronunciation

  • Classical: [bɛl.lɪˈkoː.sʊs][1]
  • Ecclesiastical: [bel.liˈkɔː.s̬us][1]

Forms

bellicōsus (feminine bellicōsa, neuter bellicōsum, superlative bellicōsissimus); first/second-declension adjective[1] An older spelling is duellicōsus.[2]

Etymology

It is from Latin bellicus (“of war”) + -ōsus.[3][4][5] bellicus is formed from bellum (“war”), older duellum, whose origin is uncertain; de Vaan thinks the best proposal is Pinault's, a diminutive *duenelo- of bonus (“good”), "deed of valour", used as a euphemism for war.[6]

Earliest recorded meaning

Köbler dates it from Cicero, who speaks of savage, barbarous and warlike peoples.[7][2]

Semantic evolution

It describes people fond of war, warlike or martial, as Cicero's most warlike nations.[3][2] Livy also uses it of times and actions, as of a man who put off his consulship to a more warlike year.[3] Lewis & Short note that it is used mostly of persons.[2] Glossaries explain it as eager to fight.[4] Church Latin glosses it warlike, of war.[8]

Timeline

  • 81–43 BC – Cicero of warlike peoples.[2][7]
  • 59 BC–17 AD – Livy of a more warlike year.[3][7]
  • early 15th century – English bellicose is borrowed from it.[5]
