infrangible
Impossible to break
Infrangible means unbreakable or inviolable.
The word applies to things that cannot be broken, whether physical objects or abstract commitments: an infrangible bond between siblings, infrangible rights.
The term is formal and literary, more likely encountered in legal or philosophical contexts than everyday speech.
