author
Latinoriginator, the one who causes or produces; the source of authority
About This Root
The root author comes from Latin auctor, which meant the person who makes something happen — a founder, a promoter, the one who sets a thing in motion. auctor is built on the verb augere, 'to make grow, to increase, to promote' (the same root that gives us augment and auction). So at the very bottom, an auctor is someone who causes growth — who takes nothing, or a little, and brings forth something real.
That one idea — the originator — fans out in two directions.
First, the creative direction. The person who originates a piece of writing is its author: the one who made the work come into being. From there: to author a book (verb), and the trade of authorship.
Second, the power direction. If you are the originator of an action or a rule, you carry weight over it — you have authority. Latin auctoritas was exactly this: the standing of the one whose word started things. English splits authority into several layers that all trace back to the same source:
- authority = the power to give orders, OR the people who hold that power (the authorities, the local authority), OR a trusted expert (she's an authority on Roman law).
- authoritative = carrying the weight of the original source — reliable and definitive (an authoritative biography), or commanding obedience (an authoritative tone).
- authoritarian = worshipping authority for its own sake — demanding total obedience, dictatorial.
- authorize (auctor + -ize) = to give someone authority — to grant them official power to act; and authorization, the act or document of doing so.
Notice the chain: augere (make grow) → auctor (the one who brings about) → author (brings a work about) and authority (the weight of the one who brings things about) → and from authority comes the whole legal-political family of authorize, authorization, authoritative, authoritarian.
One useful warning: author and augment and auction are all distant cousins through augere 'increase' (an auction literally increases the price by bidding). But the au- in audio or automatic is unrelated — don't let the spelling fool you.
An author is the one who brings a book into being — the originator. Stretch that idea: whoever originates something gets the weight over it. That weight is authority. Every author- word is about the originator and the power that comes with originating: authorize = grant that power, authoritarian = obsessed with it.
Core Words Deep Dive
The few words from this family worth telling in full — one by one.
The most direct member: the one who *makes a work come into being*. Latin auctor (originator) narrowed in English to the maker of a written work. The verb 'to author a book' revives the original 'bring into being' sense, and now extends figuratively — to author a policy, author a plan.
The pivot word, and richly multi-sense. From auctoritas, 'the standing of the originator.' English layers three meanings on it: (1) the power to give orders; (2) the body that holds that power — the authorities, the local authority; (3) a trusted expert whose word carries weight — an authority on something. All three are 'the weight of the source.'
authority + -arian (a believer in / advocate of, as in vegetarian, libertarian). So an authoritarian is literally 'one who worships authority' — someone who values obedience to authority above freedom. The word leans negative: authoritarian rule, an authoritarian parent. Contrast with authoritative, which is positive (reliable, commanding).
auctor + -ize ('to make / cause'): to give someone authority — to grant official power to act. To authorize a payment is to lend it your weight as the legitimate source. Its noun authorization is the act or the document granting that power. Note the British spelling authorise.
Related Roots
author traces back to augere 'to make grow, increase' — the same source as augment and auction. The auctor was literally 'one who makes things grow / brings them about.' If you remember that author and augment share a root, the 'originator → increase' link becomes obvious.
Both touch on power and rule, but from different angles. author/authority is about the weight of the originator — the source whose word starts things (authorize, authority). reg (regere 'to rule, keep straight') is about governing and directing: regulate, regime, regent. Quick test: source of legitimacy → author; act of ruling → reg.
potent (from posse 'to be able') is raw power — the capacity to do or affect (potent, potential, omnipotent). authority is power that is recognized and legitimate — the right to command, granted by one's standing as originator. A tyrant can have power without authority; a judge has authority backed by power.
