authority

*Authority* does not begin with power.‌​‍​‍​‍​‌​‌​‍​‍​‌​‍​‌​‍​‌​‌​‍​‍​‍​‌​‍​‌​‍​‍​‌​‌​‌​‌​‍​‍​‍​‍​‍​‌ It begins with growth.

The word traces back to the Proto-Indo-European root *h₂ewg-*, meaning *to increase* or *to enlarge*. From this root came Latin *augēre* (to increase, to cause to grow), which produced *auctor* — one who increases, who originates, who causes something to come into existence. From *auctor* came *auctoritas*: the influence, credibility, and standing that belongs to the person who originated a thing.

Authority is, at its etymological core, the credibility of the one who made something grow.

Latin *auctor* carried a specific and concrete meaning: originator, creator, promoter. The *auctor* of a law was its proposer — the senator or magistrate who brought it into being. The *auctor* of a building was its commissioner. The *auctor* of a deed was the guarantor who stood behind it.

The concept did not imply dominion in the coercive sense. It implied origination — and from origination came the right to speak about the originated thing, to ratify it, to stand behind it with one's weight. The *auctor* had authority not because he commanded, but because he had made something real. This distinction matters enormously for understanding how the word has shifted across the centuries.

From *auctor* descended *auctoritas*, which entered Old French as *autorité* and Middle English as *autorite* — arriving in its modern English form in the thirteenth century, carrying the full weight of its Latin legal and rhetorical inheritance.

*Author* and *authority* are siblings from the same Latin parent. Both descend from *auctor*. In Latin, the relationship was transparent: the *auctor* of a text was its author, and the *auctor*'s standing in relation to that text was precisely his *auctoritas*.

An author has authority over a text because the author originated it. The semantic connection was not a metaphor — it was a direct expression of the same underlying concept. The one who brings a thing into existence has the standing to speak for it, to be consulted about it, to ratify or amend it.

The modern English separation of *author* (creative, literary) from *authority* (political, institutional) obscures what was once a single coherent concept. The writer and the official once shared a word because they shared a logic: both possessed standing derived from origination. When we now speak of an expert as an *authority* on a subject, we preserve a trace of the older meaning — the person who has, in some sense, made something grow in that domain.

The reach of *h₂ewg-* across the lexicon is a study in how a single root for *growing* can structure vocabulary for creation, commerce, politics, religion, and the calendar.

- *Augment*: to make larger — Latin *augmentum*, directly from *augēre* - *Auction*: a sale in which the price increases — from Latin *auctio*, a public sale driven upward by competing bids - *August* (adjective): deserving of increased respect, venerable — from Latin *augustus*, which Octavian adopted as a title in 27 BCE, claiming for himself the name of something sacred and growth-filled - *August* (month): renamed from *Sextilis* in honour of Augustus, who accumulated enough *auctoritas* to have a month reshaped in his image - *Inaugurate*: to install with augury — from Latin *inaugurare*, itself from *augur*, the official who read signs of increase and divine favour in the flight of birds. The *augur* too derives from *h₂ewg-*: one who reads the signs of growth and increase - *Auxiliary*: providing an increase of strength — Latin *auxilium*, from *augēre* - *Eke*: the archaic English word meaning to increase, surviving in the phrase *eke out a living* — a direct Germanic cognate of the same PIE root, preserved at the edge of English vocabulary while its Latin relatives colonised the centre

One root for growing: behind the writer, the auctioneer, the Roman emperor, the priest reading bird-flight, the soldier's reinforcements, and the man stretching his last provisions to the month's end.

The transit from *origination* to *power* runs through Roman law.

In the Roman constitution, *auctoritas* was a precise technical term — the ratifying influence of the Senate, distinct from *potestas* (the formal, coercive power held by magistrates) and from *imperium* (military command). The Senate held *auctoritas*; consuls held *potestas*. The distinction mattered: *auctoritas* was the weight of accumulated standing and wisdom, not a power that could compel. Augustus' political genius lay in understanding that *auctoritas* could be more durable than *potestas* — he dismantled the coercive machinery of the republic while claiming to hold only the Senate's ratifying influence, and in that sleight of hand transformed *auctoritas* into something that looked, in practice, very much like absolute power.

The distinction between the two concepts gradually collapsed. As *auctoritas* absorbed the functions of *potestas*, the English *authority* inherited both — the originator's standing and the state's compulsion — in a single word. What had been a nuanced legal vocabulary became, in transmission, a fusion of ideas the Romans had carefully kept apart.
