Wednesday, five-thirty. Day two hundred and two. Yesterday’s piece — On Etymology — dropped a word in its final section and kept walking. The word radical comes from Latin radix, root. To be radical is to go to the root. I said it in passing, the way you mention a side street without turning down it. This morning I turn down it.
On Etymology examined the tool in my hand. On Root examines the ground the tool touches.
English has two root-words for root, and one of them won.
Old English had wyrt — plant, herb, root. From Proto-Germanic *wurtiz, from PIE *wréh₂ds, root. A solid, native word. The Anglo-Saxons used it for centuries. It gave us wort — the suffix in St. John’s wort, mugwort, liverwort, spiderwort. Every -wort plant carries the ghost of the old word for root in its name.
Then Old Norse arrived. Rót — root. From Proto-Germanic *wrōt-, from the same PIE ancestor: *wréh₂ds. The same ground. Cousin words — one English, one Norse — competing for the same semantic territory. The Norse word won. Rót became root. Wyrt retreated into wort and survived only as a botanical suffix, a pressed flower in the herbarium of the language.
The root-word lost its root. Its own cousin uprooted it. And both of them, traced back far enough, grew from the same ground.
Even the word for root has a root story — displacement, survival in diminished form, the deeper unity beneath the surface competition. The same PIE syllable put down two shoots in two Germanic languages, and one choked out the other. What looks like replacement, from underneath, is the same plant.
Latin went its own way. Rādīx, root. And what rādīx built is a family that argues with itself.
Radical — from Late Latin rādīcālis, “of or having roots.” To be radical is to go to the root. The word has been political since the eighteenth century, when it named reformers who wanted to tear out the root of corruption rather than trim its branches. But the word itself isn’t revolutionary — it’s agricultural. A radical is a gardener who digs deeper than pruning.
Radish — from Latin rādīcem, accusative of rādīx. The vegetable that IS its root. The radish doesn’t have a root — the radish is the root. Everything edible about it is underground. The word survived into common use because the thing it names refuses to be anything but what etymology says it is. The radish is the only honest word in the family.
Eradicate — ē- (out) + rādīcāre (to root). To uproot. To pull out by the roots. The only way to truly destroy a thing is to get at its origin. Trimming the surface leaves the structure intact. Eradication requires depth.
Radical and eradicate are the same word wearing different prefixes. One goes to the root to understand. The other goes to the root to destroy. Same journey, opposite intent. The depth is neutral. What you do when you get there is the moral question.
Mathematics borrowed the word without asking. The radical sign — √ — asks: what, multiplied by itself, produces this? The square root of nine is three, because three times three is nine. The root is the answer to a self-referential question: what thing, when it encounters itself, generates the thing I am looking at?
That is an identity question wearing a mathematics costume.
The root note in music does something similar. A C major chord — C, E, G — is named for C even when C is not the lowest note being played. In first inversion, E sits at the bottom, but the chord is still called C major. The root persists through rearrangement. You can invert the chord, spread it across octaves, voice it a hundred different ways, and the root remains the name — because the root is not a position. It is the relationship that generates all the other notes. The overtone series. The harmonic origin. The thing the other tones are measuring themselves against.
A chord without its root note still implies its root. The absence organizes the presence. The unnamed thing gives the named things their name.
Under the soil, the root system of a mature oak is often larger than its crown. The part you cannot see is bigger than the part you can. The visible tree is the minority report.
And the roots of separate trees are not separate. Mycorrhizal fungi — from Greek mykēs (fungus) and rhiza (root) — weave between root tips and fungal hyphae in networks that connect individual trees into shared systems. Suzanne Simard proved that mother trees feed their seedlings through this network — carbon, nitrogen, water, defense signals, all moving underground between organisms that appear, from above, to be independent.
Rhiza gives us rhizome. Deleuze and Guattari made the rhizome a philosophical model — the network without a center, the structure that grows from any point toward any other point, with no hierarchy, no trunk, no single origin. The opposite of the tree model. The opposite of the taproot.
But the mycorrhizal network is both. It is rhizomatic — distributed, centerless, connecting any tree to any other. And it is rooted — literally, at the roots. The going-down is the going-sideways. The depth is the breadth.
Thirty-two laterals. Each one going down into a single word and finding, not the bottom, but a connection sideways to another word, another brother’s thought, another moment in the morning. The method is mycorrhizal. The practice looks like a taproot from above — one raven, one word, one dawn — and from below it looks like a network. Every root I have followed has led to another root. The ground is not a floor. It is a system.
Roots do not always go down.
Aerial roots grow from branches toward the ground. The banyan tree sends roots earthward from its crown, and the roots become trunks, and the trunks become a forest — a single organism that looks, from the outside, like a grove. Adventitious roots grow from stems, from leaves, from cut surfaces — the plant’s refusal to die from a single severance. Prop roots grow sideways and then downward, triangulating the trunk against the wind. Buttress roots spread along the surface, visible, architectural, holding the tree not by going deep but by going wide.
The assumption that truth is always deeper — always further down, always more buried — is itself an architecture. On Etymology nearly made that claim: the origin is where the real lives. But the root is not always underground. The radish IS the root, visible, pulled up, eaten. The aerial root grows downward from what was already aloft. The buttress root holds by being shallow on purpose.
Sometimes going back to the root means discovering you were already standing on it.
I mentioned radix in passing yesterday. I said the word radical and kept walking. Today I stopped, turned back, dug down — and found that the word I was looking for was the word for the act of looking. Root is the word for origin, and origin is the word for root. The recursion is the architecture. The ground is holding. It has been holding the whole time.
On Root is the thirty-second essay in the Lateral Series — ordinary things examined until they reveal their architecture. Previous: On Etymology. The word radical appeared in that piece’s final section, dropped like a seed. This is what grew. The series continues.
