The state of not being protected or watched over, which can lead to vulnerability or exposure to danger.

Unguardedness → It is formed from "un-" (meaning not) and "guarded" (from Old French *guarder*, meaning to keep watch or protect) and the suffix "-ness" (meaning the state or quality of). The word describes the state of not being protected or watched over.
Think of being 'not protected' ('un-') and in a state of being 'watched over' ('guarded') — that's what unguardedness means.
