Forms

auctōritās f (genitive auctōritātis); third declension[1]

Etymology

It is from auctor “originator, guarantor” with the suffix -tās, and ⟨auctor⟩ is from augeō “to increase”.[2][1][3][4] Lewis and Short reject the spellings ⟨autor-⟩ and ⟨author-⟩.[5]

Earliest recorded meaning

The OLD's first citation is the Twelve Tables, of the right of ownership, and Köbler dates them about 450 BC.[2][3]

Semantic evolution

In law it meant the right of ownership, title, as the Twelve Tables' ūsus auctōritās “usucapion”.[2][6] It meant authorization, sanction, responsibility for an action, as in Plautus, an informal decree of the senate, a proposal or advice, and guidance.[2] It meant the right to sanction, controlling influence, authority, of laws force, of magistrates command, as in Cicero, and leadership, influence.[2] It meant authoritativeness of speech or style, weight, a weighty opinion, a precedent, prestige, personal ascendancy, as in Terence, and of things repute.[2]

In Medieval Latin it meant a king's order or ordinance, a charter, a title, and accepted tradition.[7][8] It survives in French autorité, Italian autorità and Spanish autoridad.[1] Through Old French it is the source of English authority about 1200, first of an authoritative passage or book.[4]
