Etymology: Rashness is about as plain as English compounds get: the adjective "rash" with the suffix "-ness" attached, turning a quality into a noun. The more interesting history lies in the suffix. "-ness" descends from an ancient Germanic ending that formed nouns from adjectives, and it traces back through Proto-Germanic and Proto-Indo-European forms that were already doing this job thousands of years before English existed. Its Old English form was "-nes," and it passed through Middle English "-nesse" into the modern spelling. Because the suffix is so productive, it can be attached to almost any adjective, which is why English speakers can coin new abstract nouns on the fly. "Rashness" is one of countless examples where a simple native ending turns a descriptive word into a name for a behaviour or state.
