## AI Etymology
inofficial comes from in- ('not') + official, from Latin officialis ('of an office'), from officium ('duty, service'), from opus ('work') + facere ('to do'). An archaic variant of unofficial. 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 "not official; lacking formal authority (archaic for unofficial)", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as official, office, and unofficial, and in derivatives such as inofficially. Its semantic neighborhood includes unofficial, informal, and unauthorized, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin in- and Latin officium.
