Why this word is great
PROBITY — [Noun] The quality of having strong moral principles, characterized by integrity, decency, and honesty. From Middle French probité, from Latin probitās ("uprightness, honesty"), from probus ("good, excellent, honest"), a word that once described a coin of pure metal, its value inherent. Unlike rectitude, which suggests a formal, sometimes rigid adherence to a code, or honesty, a baseline of transactional truth-telling, probity is a deeper, weathered and intrinsic virtue. It is the judge who recuses herself from a friend’s case, the clean ledger audited only by conscience, and the unshakable hand returning excess change—a quiet, unadvertised fidelity to the good, which in its constancy becomes the silent architecture of a trustworthy soul, a gentle, unyielding gravity.
