Foolhardier → It is formed from "fool" (from Old English *fola*, meaning a person lacking sense) and "hardy" (from Old French *hardi*, meaning bold or brave). The word "foolhardier" describes someone who is recklessly bold or daring, often without regard for danger or consequences.
Think of someone who is both a 'fool' and 'bold' — that's why foolhardier means recklessly brave.
