reasonability

Quality of fairness

Reasonability is the quality of being reasonable—sensible, fair, and showing sound judgment.

The word overlaps almost entirely with reasonableness, though reasonableness is far more common.

Reasonability appears most often in legal and business contexts: The court will assess the reasonability of the defendant's actions.
