Pronunciation

  • Classical: [ak.kuː.saːˈtoː.ri.ʊs][1]
  • Ecclesiastical: [ak.ku.s̬aˈtɔː.ri.us][1]

Forms

accūsātōrius (feminine accūsātōria, neuter accūsātōrium, adverb accūsātōriē); first/second-declension adjective[1]

Etymology

It is from Latin accūsō (“to accuse”) + -tōrius,[2] the adjective belonging to accūsātor (“accuser”).[1][3] accūsō is a compound of ad (“to”) and causa (“cause, lawsuit”).[1]

Earliest recorded meaning

Its first known use is in Cicero, in the speech for Sextus Roscius, of the craft of a professional prosecutor.[2][4]

Semantic evolution

Cicero uses it often: of the prosecutor's right and custom, a prosecutor's spirit, a law on prosecutions and the usual methods of accusers, which he declines to use.[2][5][3] Livy speaks of an accuser's voice and spirit, Seneca the Elder of an accuser's pugnacity and Quintilian of an accuser's life.[5][3][6] In the Digest, Ulpian uses libellī accūsātōriī of written charges.[2][5] Augustine contrasts an accusing word with a pleading one.[6] The adverb accūsātōriē, “in the manner of an accuser”, is found in Cicero and Livy.[5][3]

In Ecclesiastical Latin it meant accusatory, of an accusation.[7] English borrowed it around 1600 as accusatory.[8]
