probity

Probity describes a rigorous, uncompromising adherence to the highest ethical standards. It suggests a level of integrity that is not merely the absence of corruption, but a proactive, steadfast commitment to truth and decency, often in professional or official capacities. This noun is uncountable and does not have a plural form. It is used to describe an abstract quality of character, meaning it cannot be counted as individual units and requires partitive constructions like a sense of probity if quantification is needed.
