probity

This is one of those words that sounds like it should wear a wig and sit on a bench. In Roman Latin, probus meant something like “good, respectable, upstanding,” the kind of adjective you’d want attached to a magistrate rather than a pickpocket. Latin then built probitas, and French passed it along as probité, so English inherited a noun that feels almost ceremonial: not just honesty, but the polished, public version of it. The family resemblance is sneaky too—probus lives near the prove/probe neighborhood, where the idea is testing something until it shows its worth. So probity is basically goodness that has been examined, stamped, and found fit for respectable company.
