Pronunciation

  • Classical: [kʷae̯ˈsiː.tɔr][1]
  • Ecclesiastical: [kʷeˈs̬iː.tor][1]

Forms

quaesītor m (genitive quaesītōris); third declension[1]

Etymology

It is from Latin quaerō (“to seek, inquire”) + -tor, from the perfect stem ⟨quaesīt-⟩;[2][1][3] Wiktionary compares quaestor, made from the present stem.[2][1][3] De Vaan traces the verb to Proto-Italic *kʷai-s-e/o- and Proto-Indo-European *kʷeh₂-i- (“to acquire”).[4]

Earliest recorded meaning

Köbler dates it from Cicero,[3] who writes of those in danger of prosecution who avoided this investigator and judge.[2]

Semantic evolution

It is first a member of an extraordinary commission to investigate a case, later the president of a criminal court, and perhaps any judge in a criminal trial: the Rhetorica ad Herennium says it is his task to keep accuser, defender and witness to their parts, and Sallust has three such investigators appointed under a law.[2][5] Virgil gives the title to Minos, judge of the dead.[2][5] It is also a seeker or inquirer: Gellius explains the Sceptics as investigators and considerers, and Seneca calls the wise man a keen searcher for natural riches.[2][5] In Medieval Latin it is a plaintiff.[6] Church Latin glosses it investigator.[7]

Timeline

  • 81–43 BC – Cicero of a criminal investigator.[2][3]
  • 86–34 BC – Sallust of three commissioners.[2]
  • 70–19 BC – Virgil of Minos.[2][5]
  • c. 165 AD – Gellius of the Sceptics.[2][3]
