Where Real Magic Words Came From

A Prescription You Wore, Not Spoke

The word appears in the Liber Medicinalis, also circulated under the title De medicina praecepta saluberrima, a Latin didactic poem of 1,115 hexameters, remedies versified so they could be memorized. The disease at hand is hemitritaeus, the semitertian fever, a malaria-type intermittent fever that Serenus rates deadlier than its kin. His prescription survives verbatim. Write abracadabra on papyrus. Repeat it on the line below, dropping a letter each time, so the figure narrows as it descends. Stop when the letters have shrunk to a cone. Then tie the charm around the patient's neck with linen thread.

Notice what is missing. Nobody says the word. Abracadabra started life as a written object, an amulet whose triangular shape was the whole mechanism, the fever meant to dwindle as the word dwindled, letter by letter, down to a point. The theatrical bark that later centuries put in a conjurer's mouth began as something closer to a pill.

The same passage offers lion's fat as an alternative remedy, which fixes the register precisely. In Serenus's toolkit the word sat next to animal grease, one option among several for an illness Roman medicine could not touch. A magic word, at its origin, was simply the treatment that remained when the real ones ran out.

An Author Vouched For by Liars

What we know of Serenus's end comes from the Historia Augusta, a source with a deserved reputation for invention. It reports that he was put to death at a banquet in December 212 AD, along with other friends of Geta, after Caracalla murdered his brother. The same text credits Serenus with a library of 62,000 volumes, a figure as suspect as everything else in that text.

So the oldest magic word on record comes with an author whose biography is partly legend, killed, if the story holds, for tutoring the wrong prince. That blend of hard fact (the poem exists, the line survives) and dubious embroidery (the banquet, the library) is worth remembering. It is exactly the texture an invented incantation's backstory should have.

The Etymology Is an Honest Shrug

Where the word itself came from, nobody knows. The Oxford English Dictionary's verdict is blunt, 'no documentation has been found to support any of the various conjectures'. Candidates floated over the years include the Greek abraxas and a run down the alphabet, alpha-beta-gamma-delta. None of them holds.

The most popular modern story, that abracadabra is Aramaic for 'I create as I speak', collapses on contact with an Aramaic dictionary. The Aramaic translator Steve Caruso worked through it. The root דבר (dbr) means to direct or to lead, not to speak, since the speech verbs are amar and malel, and 'I create' would come out as /ebra/, not /abra/. His conclusion is flat. The phrase cannot be Aramaic.

The Paper Trail Behind Avada Kedavra

The Aramaic story is wrong, but it is wrong in a traceable way. The trail runs through cyclopedias of 1891 and 1906 that mixed Persian and 'Chaldee' derivations, a 1967 Saturday Review piece offering 'abhadda kedabrah, vanish at this word', and Stephen Jay's 1977 book Abracadabra, which glossed it 'May be from the Aramaic: Avada Kedavra, may the thing be destroyed'. In 1999 a Straight Dope message-board post spread it across the early web, crediting Rabbi Lawrence Kushner, whose 1993 The Book of Words had rendered 'I create as I speak' as 'avara k'dvara'.

Then the garbled version cast its biggest spell. At the Edinburgh International Book Festival on 15 August 2004, J.K. Rowling said of Avada Kedavra, 'It is an ancient spell in Aramaic, and it is the original of abracadabra, which means let the thing be destroyed'. The wording matches Jay's 1977 gloss almost exactly. By then the fake etymology had outperformed every real conjecture on record.

For a worldbuilder this is the useful part. An etymology does not need to be true to function. It needs a chain of citations, each slightly garbling the last, and one authoritative voice repeating the result with confidence. Build that chain for your own incantation and it will feel excavated rather than invented.

Hocus Pocus Had a Performance License

Hocus pocus began as a performer's brand, not as folk Latin. Ben Jonson's Masque of Augures (1621) features a 'Hochos-pochos'. John Gee's anti-Catholic tract of 1624 names 'Hocas Pocas' as a juggler. And a court record dated 18 November 1625 identifies one 'William Vincent, alias Hocus Spocus' as the King's servant, a licensed stage magician whose performance license dated back to 1619. The most famous nonsense in English was a working entertainer's stage name.

We even have his script. Thomas Ady's witch-hunting critique A Candle in the Dark (1655) preserves the full patter Vincent used to misdirect audiences, 'Hocus pocus, tontus talontus, vade celeriter jubeo'. Only the last three words mean anything, 'go quickly, I command'. The rest is rhythm, sound deployed as cover fire for the hands. A theory proposed by John Tillotson, later Archbishop of Canterbury, in a sermon published in 1684 held that hocus pocus parodied the Mass formula 'hoc est corpus meum'. Modern references treat that as unproven, and Oxford dictionaries offer a rival source, the sham-Latin conjurer's formula 'hax pax max Deus adimax'.

The stage word then shed skin into everyday English. Etymologists derive 'hoax' from 'hocus', attested as a conjurer in the 1630s and a cheat by the 1680s, or directly from hocus-pocus itself, with 'hoax' first recorded as a verb in 1796 and as a noun in 1808. Jugglers kept minting variants, among them the 1670s formula 'hiccus doccius'. Nonsense with the right cadence turns out to be renewable.

Skeptics at the Plague Door

The fever charm outlived its inventor by centuries and collected enemies. Daniel Defoe, in A Journal of the Plague Year (published March 1722 and depicting the London plague of 1665), scorned Londoners who posted abracadabra on their doorways as protection. The Puritan minister Increase Mather likewise dismissed the word as powerless. Some fourteen centuries after Serenus, the charm was still in use and still failing, now against a different disease.

Believers kept adjusting it too. Aleister Crowley respelled the word 'Abrahadabra' in The Book of the Law, the central text of Thelema, swapping an H for a C on Hermetic Qabalah numerological grounds. A single letter, in that tradition, changed what the word was for. Skeptic and occultist agreed on one thing, the exact spelling mattered.

Coining Incantations with the Same Texture

Strip these histories down and a small toolkit remains. Reduplication with one sound swapped, as in hocus pocus, tontus talontus, hax pax max, and hiccus doccius. A meaningful tail hidden in a nonsense body, the way 'vade celeriter jubeo' rides behind Vincent's gibberish. A physical procedure, since abracadabra was written, shrunk, and worn on linen thread long before anyone shouted it. And a firm refusal to mean anything, which keeps an incantation from dating the way ordinary vocabulary does.

So give an invented spell-word the same apparatus. Decide what disease or disaster it originally treated. Give its written form a rule, letters dropped, doubled, or stacked into a shape. Draft the court record of the charlatan who performed under it and the sermon that denounced it. Then write the wrong etymology, the confident one everybody repeats.

Names help too. A wizard's signature incantation lands harder when it shares sounds with the wizard, the way the court clerk filed William Vincent under Hocus Spocus. A batch cued on the wizard namer will hand you the names, and the syllable worth reduplicating is usually already in there.
