Word Origin

Inviolable derives from the Latin inviolabilis, meaning “that cannot be harmed” — built from in- (“not”) and violabilis (“able to be violated”), from violare (“to violate” or “to dishonor”), itself from vis meaning “force.” The same root gives us violate, violent, and inviolate — all words built around the idea of force applied against something that should be protected. It entered English in the 15th century, used in legal and religious contexts to describe rights, oaths, and sanctuaries that existed beyond the reach of ordinary power.
