inaugurate (v.)
"induct into office by formal ceremony," c. 1600, a back-formation from inauguration (q.v.) and also from Latin inauguratus, past participle of inaugurare. The etymological sense is "make a formal beginning or induction into office with suitable ceremonies" (which in ancient Rome included especially the taking of auguries). The earlier verb in English was augur (1540s). Related: Inaugurated; inaugurating; inaugurator.
