Origin
From PIE *h₂ewg- (to increase), through Latin augēre and auctor (one who originates), authority first named the credibility of a creator over what they had brought into existence — only acquiring its modern sense of coercive power through the slow collapse of a Roman legal distinction between origination-based standing and formal state force.

The Full Story

The word 'authority' enters Middle English in the early 13th century via Old French 'autorité', which itself derives from Latin 'auctoritas'. The Latinnoun 'auctoritas' was formed from 'auctor' — the originator, promoter, guarantor, or author of something — plus the abstract suffix '-itas'. The earliest and most precise meaning of 'auctoritas' was

The words author, authority, auction, augment, august, inaugurate, and the humble English eke all descend from a single PIE root meaning 'to increase'. When Augustus took his title in 27 BCE, when an auctioneer drives up a bid, when a writerclaims authority over their text, and when someone ekes out a living, they are all drawing on the same ancient idea — that credibility, dignity, and value come from the act of making something grow.
and of great orators. The root Latin verb is 'augēre' (to increase, to make grow, to originate), which derives from the Proto-Indo-European root *h₂ewg- (to increase, to enlarge). This root is extraordinarily productive. 'Augēre' also generated 'augmentum' → English 'augment'; 'auxilium' (an increase of strength, help) → English 'auxiliary'; 'augur' (the Roman religious official who read signs of growth and increase in bird flight) → English 'augur' and 'inaugurate'; 'Augustus' (the increased, the revered one, the title Octavian adopted in 27 BCE) → the adjective 'august' and the month 'August'; and 'auctio' (a sale in which the price progressively increases) → English 'auction'. The semantic core of *h₂ewg- links increase with origination: the person who causes something to grow is also its originator. This is why 'auctor' means both 'originator' and 'guarantor' — the one who made something exist carries permanent moral responsibility for it. Key roots: *h₂ewg- (Proto-Indo-European: "to increase, to enlarge; cognate with Old English 'ēacian' (to increase), Greek 'auxein' (to increase), Sanskrit 'ojas' (strength, vigor)"), augēre (Latin: "to increase, to grow, to originate — direct verbal ancestor of auctor, auctoritas, augment, auxiliary, augur, Augustus, auction"), auctoritas (Latin: "the moral weight and credibility of an originator; the standing that flows from having caused something to come into being").
