How Magic Works: The Law of Words of Power

How Magic Works · Part 6 of 7 — the real principles behind every spell, one law at a time.

The Law of Words of Power is the sixth of the seven foundational laws, and it can be stated in a single line: some words, said aloud, do not describe the world — they change it. To speak them, properly and in the right place, is not to report something but to do something. Most words point at the world; these ones act on it.

You already use words like this every day, without thinking of them as magic. When two people say “I do,” they are not describing a marriage — they are making one; the words themselves are the wedding. “I name this ship the Queen Elizabeth,” said as the bottle breaks against the hull, does not report the ship’s name but gives it. A judge’s verdict, a witness’s oath, a promise, a blessing — none of these merely describes a state of affairs. Each one accomplishes something in the saying. Philosophers call them performative words, and they are the plainest proof that a spoken word can be an act.¹

The oldest and highest form of the idea is the word that makes things be. “And God said, Let there be light: and there was light” — in Genesis, creation itself is spoken into existence, command by command. The Gospel of John reaches for the same mystery in its very first line: “In the beginning was the Word.” Across traditions, the deepest power of all has been imagined not as a hand that shapes but as a voice that speaks.²

The magicians of the ancient world built their craft on this. The Egyptians held that the right words, uttered in the right voice by the right person, carried real force — a power their later translators rendered as “words of power.” The Greek spellbooks are crowded with strange, untranslatable words whose power was felt to lie precisely in their strangeness — foreign, resonant, unlike any everyday speech. In India, the chanted mantra and the sacred syllable were held to carry the very essence of the cosmos in sound. Everywhere the conviction was the same: that certain words are charged, and that to voice them is to reach something real.³

We still keep one of these words, though we have long forgotten what it meant. “Abracadabra” is the word a child says over a trick, the very sound of magic — but it began in deadly earnest. A Roman physician, almost two thousand years ago, prescribed it against a burning fever: write the word on a scrap of parchment, he instructed, then again beneath it with the last letter missing, and again shorter still, until it dwindles to a single letter and a shape like a cone — and wear it at the throat, so that as the word shrinks away, the fever shrinks with it. What it first meant, no one now knows; its origin is genuinely lost. But that we still reach for abracadabra when we want to say magic shows how deep this law runs.⁴

For most of history, a spell was something said. The old healing charms had to be spoken exactly, and spoken aloud — a word misremembered was a charm undone. One of them, written down in Germany a thousand years ago to mend a broken limb, runs “bone to bone, blood to blood, limb to limb, as though they were mended” — the words doing, in the mouth, what the healer hoped the body would do. The saying was the medicine.

The two plainest survivors of this law are the blessing and the curse. To bless someone, or to curse them, has never felt like merely describing a wish — it feels like doing something to the person, sending something toward them that the words themselves carry. In that instinct, which nearly everyone still feels, the Law of Words of Power is alive and unbroken.

That is the Law of Words of Power: the word that does rather than describes, the sound that acts. And it brings us to the last of the seven laws — because a word, however charged, is only a word until someone means it. Behind every spoken spell stands the force that gives it life: the caster’s own will.⁵

What to Remember

The Law of Words of Power: some words, said aloud, don’t describe the world — they change it; to speak them is to act.
You use it daily: “I do,” a verdict, an oath, a blessing — words that do, not merely describe.
Its grandest form is creation itself: “And God said, Let there be light: and there was light.”
The old magicians built on it: Egyptian “words of power,” the strange words of the Greek spellbooks, the chanted mantra.
Abracadabra is the law in a single word — once a Roman fever-charm, its meaning now lost.
Next: the Law of Will — the force behind the word.

Frequently Asked Questions

What is the Law of Words of Power?

The principle that certain words, spoken or written in the right way, do not merely describe the world but act on it — that to say them is to do something, not to report something.

Is this law really still used?

Yes — more than most. We live by it whenever a vow, an oath, a verdict, or a blessing changes something simply by being spoken. Philosophers call these “performative” words, and magic has always worked on the same principle: the spoken spell, the written petition, the chanted charm.

Where does “abracadabra” come from?

It is first recorded nearly two thousand years ago, in a Roman medical book, as a charm against fever — written in a shrinking triangle and worn at the throat. Its original meaning is unknown; several derivations have been proposed, but none is certain.

Sources

The philosopher J. L. Austin named these “performative” utterances in How to Do Things with Words (1962): to issue one “is not to describe my doing … it is to do it,” as with “I do” in a marriage or “I name this ship the Queen Elizabeth.” The anthropologist S. J. Tambiah treats ritual speech the same way in “The Magical Power of Words” (Man, 1968). This is why the law holds even outside magic: some words genuinely accomplish things by being spoken.
Genesis 1:3 and John 1:1, King James Version. “Word” in John renders the Greek logos — the divine expression.
E. A. Wallis Budge coined the English phrase “words of power” for the Egyptian hekau in Egyptian Magic (1899); his Victorian translations are dated, and modern Egyptology understands heka more broadly as the creative force of magic itself (see Robert K. Ritner, The Mechanics of Ancient Egyptian Magical Practice, 1993). On the Greek magical papyri and their voces magicae, see Hans Dieter Betz, ed., The Greek Magical Papyri in Translation (1986). On sacred sound in India, Om is called the greatest of the mantras; the popular “vibration/frequency” framing, though, is a modern addition, not ancient doctrine.
The earliest source for “abracadabra” is the Roman physician Quintus Serenus Sammonicus, Liber Medicinalis (conventionally 2nd–3rd century, though its authorship is debated), who prescribed writing it in a diminishing cone as a fever amulet. Its etymology is genuinely uncertain — Hebrew, Aramaic, and Gnostic derivations have all been proposed, and none established. The healing charm quoted (“bone to bone, blood to blood”) is one of the Merseburg Charms, written down in the 9th–10th century.
The modern name for this law is Isaac Bonewits’s Law of Words of Power in Real Magic: “there exist certain words that are able to alter the internal and external realities of those uttering them.” (James Frazer, who named the Laws of Similarity and Contagion, has no separate law of words — in his scheme the incantation runs through sympathetic magic rather than standing on its own.)
