What does probity mean?
Probity is a formal noun meaning honesty, integrity, and moral uprightness. It describes conduct that is not merely technically legal or outwardly respectable, but genuinely trustworthy and ethically sound. The word is especially common in discussions of business, government, law, and public service, where it suggests that people and institutions act honestly and do not misuse their positions or the trust placed in them. In ordinary conversation, “integrity” is often more natural, but “probity” has a somewhat elevated, traditional tone that can lend weight to a statement about trustworthy conduct. A person noted for probity is someone whose actions are consistently guided by moral principles. A matter of probity concerns whether honesty and ethical behavior have been upheld. The word may also imply firmness: genuine probity involves refusing to engage in deception or corruption even when doing so could be advantageous.
