Pronunciation

  • Classical: [prae̯ˈtoː.ri.ʊs][1]
  • Ecclesiastical: [preˈtɔː.ri.us][1]

Forms

praetōrius (feminine praetōria, neuter praetōrium); first/second-declension adjective[1] Inscriptions also spell it pretōrius.[2]

Etymology

It is formed from Latin praetor (“praetor, commander”) + -ius.[3][1][2] De Vaan derives praetor from ⟨*prai-itōr⟩, “one who goes before”, from prae and eō (“to go”).[4]

Earliest recorded meaning

Köbler first records it in Cicero,[5] who has the cohors praetōria, a commander's bodyguard.[3]

Semantic evolution

Praetōrius first belongs to a military commander (the praetor in the old sense): the cohors praetōria was a general's bodyguard (Cicero), and under the Empire the cohorts of the emperor's guard, the Praetorian Guard.[3][6] It also belongs to a praetor or propraetor and to the powers vested in him (Varro: praetōrium iūs, Cicero: law made by the praetors' edicts), and describes a man of praetorian rank, one who has been praetor (Cicero: Balbus … praetōrius fuit).[3][6]

Church Latin glosses it “praetorian”.[7]
