Etymology

Origin of inquisitor

1495–1505; < Latin inquīsītor, equivalent to inquīsī-, variant stem of inquīrere to inquire + -tor -tor

Explanation

Inquisitor is what you call someone who asks questions in an aggressive way, like a prosecutor in a courtroom, or a parent who wants to know everything you did last night. This word comes from 4th century Rome, where the Church hired religious detectives, called Inquisitors, to root out people who disobeyed the Church's rules. So inquisitors have always been aggressive, even though there's nothing particularly harsh or aggressive about the Latin root quærere, which simply means "ask" or "seek."
