Forms

praetōrium n (genitive praetōriī or praetōrī); second declension[1]

Etymology

It is from Latin praetor (“praetor; general”) + -ium,[1][2] which the OLD derives from the adjective praetōrius (“of a praetor or general”).[3] De Vaan explains ⟨praetor⟩ as ⟨*prai-itōr⟩, “one who goes before”, from prae (“before”) and eō (“to go”).[4]

Earliest recorded meaning

Cicero and Caesar have it for the general's headquarters in camp:[3] Cicero tells of a man sacrificing in front of the praetōrium.[3]

Semantic evolution

From the general's tent it passed to the council of officers held there, as in Livy's “the council was dismissed”,[3][2] and to the headquarters of a provincial governor, as in Cicero's speeches against Verres.[3] Inscriptions use it for rest houses built along the military roads for travelling officials.[3] Under the Empire it named the imperial bodyguard, the Praetorian Guard, from Pliny the Elder and Tacitus on.[3] Juvenal and Suetonius use it for a grand country mansion: Juvenal's rich owe their gardens and palaces to crime.[3]

Church Latin has it for a palace, a governor's hall and a court of judgment.[5] Medieval Latin uses it for a manor or castle and for a hall of justice.[6]
