The quality or state of being foolishly bold or reckless; foolish bravery without proper thought or caution.
Foolhardy plus the suffix '-hood' (from Old English 'hād', meaning state or condition). This formal noun emerged in the 1500s-1600s for describing the abstract quality of foolish boldness.
Foolhardihood is delightfully archaic and formal—it sounds like something Cervantes or Shakespeare would use to describe Don Quixote's charges at windmills, capturing the tragedy and comedy of misguided courage.
