Pronunciation

  • Classical: [ak.kuːˈsaː.ti.oː][1]
  • Ecclesiastical: [ak.kuˈs̬at.t͡si.o][1]

Forms

accūsātiō f (genitive accūsātiōnis); third declension[1] Manuscripts also have accussātiō.[2]

Etymology

It is formed from Latin accūsō (“to accuse”) + -tiō.[3][1][2][4] accūsō is ad- with causa (“cause, lawsuit”),[1][5] whose origin de Vaan finds uncertain (Walde and Hofmann linked it with cūdō (“to strike”)).[5]

Earliest recorded meaning

Köbler first records it in Cicero,[6] who uses it in Dē inventiōne for the accusation as part of judicial oratory.[3]

Semantic evolution

Accūsātiō is the act of accusing, a prosecution (Cicero: the method of the courts consists of accusation and defence), and quārta accūsātiō is the fourth and last hearing of a trial before the people.[3][7] It is also the charge itself, a formal indictment, and a published speech for the prosecution, as Cicero calls a book of his Verrines; in Tacitus it is the accusations of informers.[3] Livy uses it for a reproof, as of a speaker who began by rebuking his own folly.[3][1]

Church Latin glosses it “accusation”.[8] English accusation (late 14th century) comes from it, partly through Old French.[4]
