interrogo

Interrogo, interrogare, interrogavi, interrogatum is first conjugation: inter plus rogo, "to put a question between people". It takes the accusative of the person questioned, with the subject of the question in de plus the ablative, or a second accusative for the thing asked: aliquem sententiam interrogare. An indirect question follows in the subjunctive, hence interrogavit quid fecisset.

The corpus overwhelmingly gives the perfect participle interrogatus, usually as an opening "on being asked". The false friend is worth naming: interrogo has none of the menace of English "interrogate". It is the ordinary neutral verb for asking a question, including a judge's formal one. When a Roman writer means hunting information down or pressing hard for it, the word is quaero.
