Untouchable

IMMUNE

Think of how your body defends against illness, or a legal term for being exempt from prosecution.

Untouchable" hints at something that can't be affected or harmed, which directly describes "immune"—like how your immune system protects you from illness. The word also plays on the idea of being legally or socially protected, as in "diplomatic immunity," where someone is shielded from consequences. It’s a straightforward definition with a slight nod to broader meanings of invulnerability.
