## AI Etymology
inauguration comes from Latin inauguratio ('consecration, installation'), from inauguratus, past participle of inaugurare ('to take omens, consecrate'), from in- ('in') + augurare ('to act as augur, take omens'), from augur ('augur, soothsayer'). 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 "the formal ceremony marking the start of an office or undertaking", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as inaugurate, augur, and inaugural. Its semantic neighborhood includes installation, induction, initiation, and commencement, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Latin inaugurare and Latin augur.
