inviolate comes from Latin inviolatus 'unhurt, unbroken', from in- 'not' plus violatus, past participle of violare 'to violate, do violence to', from vis 'force'. Morphologically, the prefixed shape matters: the initial element belongs to the recorded formation and helps explain the modern form's surface analysis. In present English, the adjective sense is "free from violation, injury, or desecration; intact", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as inviolable, violate, and violation, and in derivatives such as inviolately and inviolateness. Its semantic neighborhood includes intact, unbroken, undefiled, and sacrosanct, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin inviolatus and Latin violare.
