Forms
inquīsītor m (genitive inquīsītōris, feminine inquīsītrix); third declension[1]
Etymology
It is from Latin inquīrō (“to search for, inquire into”) + -tor, an agent noun formed on the participle stem ⟨inquīsīt-⟩.[2][1][3] The verb is a compound of in- and quaerō (“to seek”).[1][4]
Earliest recorded meaning
It first appears in Cicero,[4][3] who in the first speech against Verres uses it of the official charged with gathering evidence for a prosecution, and in the Academica of a person who searches into the nature of things.[5][6]
Semantic evolution
The TLL counts only two instances in Cicero and finds it regularly from Seneca and Pliny the Elder on; in verse it occurs only once, in Juvenal.[3] Besides the investigator of a lawsuit, who collected witnesses and evidence for the accuser,[5][2] it named a researcher into nature or truth, as in Seneca's Naturales quaestiones,[5][6] a hunting dog that tracks game, in Pliny the Elder,[2][7] a spy or tracker sent after a suspect, in Suetonius,[7][5] and, in Juvenal, people who search the very seaweed on the shore.[5][2]
Medieval writers kept the sense “searcher, finder”: Bede calls Pliny a most skilful investigator of nature.[8] It also named a person who held an inquest or official inquiry,[8] and in Ecclesiastical Latin an officer of the Inquisition.[9] English took it over around 1400 for an inspector, and used it from the 1540s for the officers of the Inquisition.[10]
