Pronunciation

  • US: /ɪˌnɔ.ɡjəˈɹeɪʃən/, /ɪˌnɔ.ɡəˈɹeɪʃən/[1]

Etymology

It is borrowed from Late Latin inaugurātiō (“consecration, installation under good omens”),[2][3][4][5] partly also borrowed from Middle French inauguration, recorded in French from the 14th century.[3][2][6] The Latin noun is formed from inaugurātus, the past participle of inaugurō (“to take omens from the flight of birds; to consecrate or install after taking omens”),[2][3][7] from in- (“in, on”) and augurō (“to take auguries”),[2][3] from augur, a Roman priest who foretold the future from the behaviour of birds, the source of augur.[8][3] Ayto takes augur as originally "one who performs with birds", from avis (“bird”) and gerō (“to do, perform”),[8] while Etymonline reports de Vaan's view that it first meant a ritual increase of crops, related to augeō (“to increase”).[3]

Earliest recorded meaning

Formal induction into an office or dignity; consecration, investiture: 1569, in instructions of the Earl of Moray to an ambassador.[2][5] Etymonline dates it to the 1560s.[3]

Semantic evolution

In ancient Rome the inauguratio was the ceremony by which the augurs sought the sanction of the gods for a human decision, and consecrated people or things to them;[3] by the time the word reached English, Ayto notes, the link with divination had been lost.[8] Johnson (1755) defined it as "investiture by solemn rites".[9] The verb inaugurate, from about 1600, is partly a back-formation from the noun.[3] From 1686 the noun was used attributively, much like inaugural.[2] In the 19th century it widened to the formal beginning of an era or course of action (1856, in Froude)[2] and to the ceremonial opening of a building or park or the unveiling of a statue (1861).[2] In the United States it is used especially of the ceremony that installs a president.[6]
