Pronunciation

  • IPA: UK /ɔːˈθɒr.ə.ti/, US /əˈθɔːr.ə.t̬i/[1]

Etymology

It is inherited from Middle English autorite, auctorite,[2][3] borrowed from Old French autorité (“authority, prestige, right, permission; the Scriptures”), also auctorité,[3][2] from Latin auctōritās (“invention, advice, influence, command”),[3][2] from auctor (“master, leader, author”),[3][2] the source of author.[3][2] It was usually spelled with -c- before the 16th century; the -c- was dropped in imitation of French, and the -th- was probably added under the influence of authentic.[3][2]

Earliest recorded meaning

An authoritative passage or book that settles an argument, especially a passage of Scripture: probably before 1200, in the Ancrene Riwle,[2] about 1200 in Etymonline.[3]

Semantic evolution

Legal validity, authoritative doctrine and an author whose statements are taken as correct are from about 1300.[3] The power to inspire belief, the weight of testimony, is in the OED from 1303.[4] The right to rule or command, the power to enforce obedience, is from the mid-14th century in Etymonline[3] and 1393 in the OED.[4] Middle English also used it of power coming from a good reputation.[3] Official sanction is from about 1400.[3] Those in authority are authority from the 1610s,[3] and the authorities are those in charge.[3] The spelling authority is first in Sir Thomas More, before 1535.[2] Authorize is from about 1383, in Wycliffe,[2] and authoritative from 1605.[2]
