Forms

inquīsītiō f (genitive inquīsītiōnis); third declension[1]

Etymology

It is from Latin inquīrō (“to search for, inquire”) + -tiō.[2][1] inquīrō is from in- and quaerō (“to seek”), for which de Vaan prefers Nussbaum's reconstruction as a present to Proto-Indo-European *kʷeh₂-i- (“to acquire”).[3]

Earliest recorded meaning

Köbler dates it from Plautus, where a character is told not to make him search for him.[4][5]

Semantic evolution

It is a search, and the search for truth: Cicero pairs it with investīgātiō.[2] Curtius uses it of a levy of new soldiers.[5] It is an investigation or scrutiny, as of an official in charge of the grain supply who exposed a shortage in Livy, and in law the collecting of evidence for a prosecution: Cicero objects to the examination of a candidate by his rival.[2] Tacitus uses it of spying that took away even the freedom to speak and listen.[2] In medieval Latin it is an inquiry and especially a sworn inquest, in which witnesses were questioned under oath, also of a judicial kind;[6][4] Köbler finds it in a capitulary of 821.[6][4] Church Latin uses it for the Inquisition.[7] English inquisition comes from it through Old French in the late 14th century.[8]
