The condition of being unable to be harmed or damaged.
The superhero's invulnerability allowed him to withstand any attack without injury.
Invulnerability → It is formed from "in-" (meaning not) and "vulnerabilis" (from Latin "vulnerare", meaning to wound). The word describes a state of being not able to be wounded or harmed.
Think of 'not' ('in-') being able to be 'wounded' ('vulnerare') — that's why invulnerability means being unable to be harmed.
