Why “improbity” is a great word
IMPROBITY — [Noun] A profound lack of probity or integrity; a fundamental dishonesty that corrupts character. From Latin improbitās, from in- ("not") + probitās ("honesty, integrity"). First attested in English in the 1590s. Unlike "duplicity" (which implies a forked tongue and active deceit) or "corruption" (which connotes the rot of entrusted power), improbity is the broader, colder bedrock of moral failure. It is the deliberate fudge in the ledger known only to the bookkeeper, the quiet omission in the testimony that shifts the blame, and the handshake that feels like a transaction—a steady, silent subtraction from the common reserve of trust.
