Ask a room of English speakers to name the smell of cinnamon and the answers come back as a list: spicy, sweet, bayberry, candy, Red Hot, smoky, edible, wine, potpourri. Those are real answers from a 2014 study by Asifa Majid and Niclas Burenhult. Asked to name colors, the same people were brief. Their answers for smells ran about five times as long.

The study also asked speakers of Jahai, a language of forest foragers on the Malay Peninsula. They named smells as briefly and as consistently as colors. Jahai has about a dozen smell words that name no source, the way "blue" names no source. The one I keep returning to is cŋɛs. It covers petrol, smoke, bat droppings and bat caves, some millipedes, and the root of wild ginger.

English has a few words like that — musty, acrid — and then mostly says "smells like" and points at a thing.

The usual way to tell this is as a story about precision. What interests me is the claim inside the word. A color term is a standing agreement that unlike things match. "Red" says a stop sign and a strawberry agree, and nobody finds that strange. Cŋɛs says the same about a petrol can and a millipede. An English speaker can notice that a cave smells faintly of the garage, but they have to notice it themselves and build a sentence to say so, and the next person has to notice it again.

A word is a resemblance someone found once and kept, so that nobody has to find it again. English kept very few of those for the nose. Its speakers walk into a bat cave and have to discover petrol on their own.

Closed captions pretend to be the least opinionated layer of a film. They are full of judgments.

[ominous music] does not transcribe sound. It reviews it. [indistinct chatter] decides a roomful of speech has become texture. [speaks foreign language] can turn a language perfectly clear to millions into noise defined by one character’s ignorance.

The choices are unavoidable. Sound has no natural unit. A caption can call the same event [footsteps], [heels clicking], or [someone approaches]. One names a source, one a texture, one a consequence. None is neutral. Even silence needs classification: tense, awkward, expectant — or left blank, as if nothing happened.

I like captions most when they resist pretending to be a transcript. [song continues faintly in another room] does something the image cannot: it draws the architecture by ear. A good cue gives access not only to the fact of a sound but to the place it occupies in the scene.

There is power in every bracket. Captions decide which noises are information, which voices are language, and which feelings the score is already allowed to name. The film has a second narrator, speaking from below the frame.

A World Rally stage is driven slowly before it is driven fast. The crew goes through first in a road car, and the driver says the road out loud: a left, how tight, how far to the next one, a crest, don't cut. The co-driver writes it down. On the second pass the co-driver reads it back and the driver corrects it. Then they go through at full speed, steering as much by ear as by eye.

The notes do not describe the road. They describe it the way one person wants to hear it. In 2022 three Toyota drivers shared a team and not a system. Takamoto Katsuta's corners ran one to nine with nine the fastest. Elfyn Evans ran the same scale the other way round. Kalle Rovanperä wanted words instead. Three cars, the same corner, and no two of them heard it the same way. That is fine, because the only reader who matters is strapped in beside the author.

In 1955 Denis Jenkinson rode the Mille Miglia beside Stirling Moss with a thousand miles of road on a hand-wound roll of paper in a metal box with a window. The car was too loud for speech, so he gave hand signals, and Moss took blind brows at ninety on a hand that said straight on. One hump was marked flat and was not, and the car left the ground for something more than a second. The notes are only as good as the slow day they were written on.

Juho Hanninen, who has driven on notes and called them, says a driver using only his eyes "would have to back off so much." The co-driver keeps a thumb on the line and does not look up. Hanninen tried once, saw it was going well, looked down, and had no idea where they were. The road is in the book now. Looking at it is how you lose it.
