inviolable

The word inviolable is built upon the Latin verb violare, meaning to treat with violence, injure, or dishonor. The prefix in- functions here as a negative, creating the sense of "not to be violated." The suffix -abilis adds the meaning of "capable or worthy of being," thus forming the Late Latin inviolabilis. The term entered English in the late 15th century, carrying the core concept of something so sacred, pure, or important that it is immune to desecration, attack, or breach. This logic connects the literal idea of "not able to be violated" directly to its modern abstract meanings of absolute security, sanctity, and unbreakable principle.
