author
Author, auction, augment, auxiliary, august, and augur are one word in six disguises. The PIE root *h₂eug- ("to increase") gave Latin augēre ("to increase, enlarge, enrich"), whose past participle auctus produced a noun-family that English borrowed wholesale: auctor ("one who causes to grow, originator, founder" — author), auctiō ("an increasing-event, a public sale by rising bids" — auction), augmentum ("an increase" — augment), auxilium ("help" — auxiliary), augustus ("augmented, exalted"; the cognomen the Roman Senate gave Octavian in 27 BCE, which named the month and the adjective), and augur (the state diviner, traditionally placed here as "one who consecrates growth-omens," though the etymology is contested). Greek built the same root through auxein, "to grow," giving the plant hormone auxin and the rhetorical figure auxesis. The Germanic branch built Old English ēacian, "to increase" — surviving in modern eke ("eke out a living" = supplement gradually) and, by metanalysis, in nickname (an additional name, a name eked on). Each English word descending from this root names a different specialization of one underlying act — the gesture of making-more. The verb is older than any of the institutions built on top of it.
Six English words on one Indo-European root: author, auction, augment, auxiliary, august, augur. The shared root is *h₂eug-, "to increase." Latin took the verb augēre ("to increase, enlarge, enrich") and built a noun-family from its past participle auctus: an agent noun (the one who does the increasing — auctor), an event noun (the gathering at which the increasing happens — auctiō), an abstract noun (the standing the increaser inherits — auctōritas), an adjective (the one who has been increased — augustus), and an instrumental noun (the thing that increases your power — auxilium). English imported them across centuries, from different French and Latin layers, with different scribal accidents along the way, until they look like six unrelated borrowings. Underneath, they say the same thing six ways.
In Latin, auctor was a wide word. It could name the writer of a text, the founder of a city, the originator of an action, the proposer of a law, the trustworthy historian, the seller of a property at public auction, the surety who guaranteed a transaction, the master of a doctrine. Each sense traces back to the same image: one who causes a thing to come into being, to grow, to take its standing. English narrowed the noun to its writing-sense by the 16th century, but the older breadth survives in two derivatives. Authority (Latin auctōritas) is the abstract noun of auctor: the standing that the originator inherits from the act of originating. Authorize (Medieval Latin auctorizāre) is the verb of conferring that standing — to authorize is to license a thing to grow, to give it the standing an originator would have. The institutional vocabulary of permission is built on the etymon of agency.
Latin auctiō meant "an increasing." By the classical period it had specialized into "a public sale at which bids progressively rise" — the event whose form is the price growing. The English noun auction entered in the 1590s and kept the specialized sense; auctioneer, "one who runs an event-of-increase," followed by 1708. The kinship with author is invisible in English: both descend from auctus, the past participle of augere, but they entered English on different schedules from different layers of Latin, and the connection is buried under three hundred years of separate use. Reading the etymology, the auction-hall and the writing-desk are the same room. Both are places where something is being caused to grow.
In 27 BCE the Roman Senate gave Octavian the cognomen Augustus, "the augmented one, the consecrated one, the exalted." The original force of the title was political: this man has been increased above the ordinary, his standing has been added to. The adjective augustus already meant "venerable, majestic, fit for ceremony"; the cognomen specialized it into a proper noun. In 8 BCE the month Sextilis ("sixth," counting from March in the old Roman calendar) was renamed August in honor of Augustus. The English adjective august ("inspiring reverence and admiration, solemnly grand") came from the Latin adjective directly in the 1660s, not from the proper noun — but the august person and the month August are both, etymologically, the increased. Augur, the official who interpreted divine signs before any state action could be undertaken, is traditionally placed on the same root: the augur was "one who consecrates by growth-omens," though some modern reconstructions place augur on Latin avis ("bird") instead, since bird-flight was a primary divinatory medium. The etymology is genuinely contested. What is not contested is inaugurate: "to begin with auguries," the ceremony in which the augurs took the omens before an action was permitted to proceed. Modern English keeps the formal-beginning sense; the original was a consecration.
The Germanic branch received the same root and built its own derivatives. Old English ēacian, "to increase," produced the verb eke — now mainly surviving in the phrase eke out a living, "to supplement gradually, to make a small supply go further." The verb wax (as in the waxing moon, an old-style English verb of growing) sits on an extended form of the same root, sharing the family with augēre via Proto-Germanic *wahsan. There is a smaller, more wonderful survival: the noun eaca ("an addition") combined with nama ("name") to give Old English ēacanama → Middle English ekename, "an additional name, a familiar name added to the given one." Sometime around 1450 the article and the noun were re-bracketed: an ekename heard as a nekename, and the noun changed shape — nickname, by metanalysis. The increase is still inside the word. Every nickname is etymologically an eked name, a name that grew on top of another, the addition that names the speaker's affection or contempt or familiarity. The root *h₂eug- never left the language; it just changed addresses.
To author, to augment, to augur, to auction, to authorize, to eke, to inaugurate: each is a different specialization of one underlying act, the gesture of making-more. The act is older than the institutions that use it. The texts and the auctions and the consecrations and the gradual additions are all the same act, called by different names that English borrowed from different layers of Latin and Germanic over different centuries. The root holds them together; the borrowings tell them apart. Reading the etymology back, the agent and the event and the standing and the consecration are one verb — the verb of bringing more of a thing into being than was there.
- authority — Latin auctōritas, abstract noun on auctor; "the standing of an originator." Entered English c. 1200 as autorite / auctorite; medieval senses include "an authoritative passage or statement" (the standing of the original text), "right or permission" (the standing conferred), and "dignity" (the standing as social position)
- authorize — Medieval Latin auctorizāre via Old French autoriser; to confer the standing of an originator on a thing; the verbal counterpart of authority
- authoritarian — 19th-c. English compound on authority + -arian; the doctrine that authority is itself the legitimating principle
- augment — Latin augmentum, "an increase"; the abstract-noun form of augēre with suffix -mentum. English augment (verb, late 14c.) from Old French augmenter
- auction — Latin auctiō, "an increasing"; the public sale-by-rising-bid; entered English 1590s. The image inside the word is the bid that grows
- auctioneer — English derivative on auction + -eer, 1708; "one who runs an event-of-increase"
- auxiliary — Latin auxilium, "help, aid"; related to auctus; help as that-which-increases your power to act; English 1600s
- augur — Latin augur, the state diviner of ancient Rome whose duty was to interpret omens (especially bird-flight) before any official action could be undertaken. Traditionally placed on this root as "one who consecrates by growth-omens" (de Vaan, from Old Latin *augos "increase"); a popular alternative derives from avis ("bird"). The etymology is contested
- augury — the practice or omens of an augur; from Latin augurium
- inaugurate — Latin inaugurāre, "to consecrate by augury"; the ceremony in which augurs took the omens before an action could begin. Modern English narrowed to "to formally begin"
- august (adj.) — Latin augustus, "venerable, majestic, magnificent"; entered English 1660s. Two etymological paths are proposed: (a) "consecrated by augurs, with favorable auguries" (via augur); (b) "that which is increased" (de Vaan, directly on the root). Both lead back to *h₂eug-
- August (month) — named after Augustus Caesar in 8 BCE; the month formerly Sextilis was renamed in his honor; the proper-noun route to the same etymon as the common adjective
- augend — Latin gerundive augendus, "that which is to be increased"; the term-of-art in arithmetic for the number being added to (compare addend, "that which is added")
- auxin — Greek auxein, "to grow," + -in; coined 1931 for the plant growth hormone; the hormone is named directly after the verb of growing
- auxesis — Greek auxēsis, "growth"; in biology, cell growth without division; in rhetoric, the figure of progressive amplification
- eke (verb) — Old English ēacian, "to increase," from Proto-Germanic *aukan (cognate with Gothic aukan, Old Norse auka, Old High German ouhhon); surviving in eke out a living = supplement gradually, make a small supply go further; the native Germanic descendant of *h₂eug-
- nickname — mid-15c. neke name, a misdivision of ekename (c. 1300, "an eke name"); literally "an additional name," from Old English eaca "an increase" related to eacian "to increase"; the metanalysis preserves the root inside a word whose speakers have stopped seeing it
- wax (verb, "to grow") — Old English weaxan, "to grow"; placed on an extended form of the same root, *weg-, which modern reconstructions debate as either a separate root or an extended form of *h₂eug-; the waxing moon is the surviving everyday sense
- aught — different root — Old English āwiht, "anything," from ā ("ever") + wiht ("creature, thing"); the resemblance to aug- is accidental
- authentic — different root — Greek authentēs, "one acting on his own authority," from autos ("self") + hentēs ("doer," from PIE *sene- "to accomplish"). The -th- in modern English author is a Medieval Latin scribal error caused by mistakenly assuming an authentic-style Greek origin for what is in fact a Latin word
- autobiography / automatic / autonomy — different root — Greek autos, "self"; the auto- prefix is unrelated to author despite the visual resemblance
- aurora — different root — PIE *h₂eus-, "to shine"; the dawn-word
- augite — different root — Greek augē, "luster, brightness"; the pyroxene mineral, named for its sheen
- wax (noun, the substance) — different root — Old English weax, "wax secreted by bees," from PIE *wokso-; only the verb to wax (to grow) is related
- actor — different root — Latin actor, "doer," agent noun of agere ("to drive, do, act"), from PIE *h₂eǵ-; Middle English sometimes confused author and actor, but the roots are unrelated
