Etymology and origin of the Latin word principatus
Pronunciation
Forms
prīncipātus m (genitive prīncipātūs); fourth declension[2] A neuter prīncipātum also occurs.[3]
Etymology
It is formed from prīnceps (“first, chief”) with the suffix -ātus.[2][1][3] ⟨Prīnceps⟩ is formed from prīmus (“first”) and ⟨-ceps⟩, from capiō (“to take”).[2][1]
Earliest recorded meaning
Köbler gives Cicero as its first author.[4] In the Philippics Cicero says someone had given Antony the leadership of his bandits.[2]
Semantic evolution
It is first place, leadership, pre-eminence, and then supremacy in the state: Cicero speaks of giving Cassius domination and the first place.[2] Under the empire it is the position of the Roman prīnceps, the system of the principate (Tacitus: Nerva joined the principate and liberty), the reign of one emperor, and the imperial government (Pliny the Younger).[2] In philosophy Cicero uses it for the Greek ἡγεμονικόν (hēgemonikón, “ruling part”), the governing part of a nature, as the mind in man, and once for a beginning in time.[2][5]
Church Latin glosses it “public office, rule, dominion, sovereignty”.[6] In Medieval Latin it is rule, imperial or royal rule, and an empire.[7] Wiktionary gives Late Latin “sovereignty, principality”.[1]
