reasonableness

Quality of fairness

Reasonableness is the quality of being sensible, fair, or moderate.

A reasonable person acts with sound judgment; reasonableness is the noun for that trait.

Courts often invoke the reasonableness standard—what a typical prudent person would do under similar circumstances.

The word also applies to prices, demands, or expectations that aren't excessive: The reasonableness of his offer surprised everyone.
