## AI Etymology
immunity comes from Latin immunitas ('exemption from public service or charges'), from immunis ('exempt, free'), from in- ('not') + munus ('duty, service, gift'). 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 noun sense is "protection from disease, obligation, or legal liability", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as immune, immunize, immunization, and municipal. Its semantic neighborhood includes resistance, protection, exemption, and impunity, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin immunitas and Latin munus.
