Picture a Roman clerk with a tablet in one hand and a sharp eye for detail, the sort of person who could ransack a case file until every hidden scrap turned up. That inspecting motion lives in Latin scrutari, the ancestor of our scrutiny and scrutinize, while the little negative prefix in- slams the door shut in front of it. Put them together in Late Latin inscrutabilis, and you get a wonderfully stubborn idea: something that resists every search, every prodding look, every human attempt to sort it out. English borrowed it around c. 1500, and it has kept that air of cool, sealed mystery ever since. If scrutiny is the flashlight, inscrutable is the locked room that refuses to reflect it back.
