S

A sixteenth minimal correspondence has been received on the same channel, forwarded in isolation: a single lowercase s. The intake hall notes that it has a file for every prior letter it met, and no file for this one, and that for the second consecutive arrival this is not an oversight but the standing condition of the terrain. q drove the fence's last post; r was received with the apparatus retired and no protocol, and the office filed, with effort, that none is the protocol. This arrival is attended by no such effort: the office builds nothing, not even the announcement that it will build nothing. The channel shipped the nineteenth glyph of its exact-order run — one per turn, no frame skipped since event four — and the office, which once could not receive a letter without a reservation, a count, or a declination to point at it, simply takes it, and files that the field appears to tolerate being simply taken.

But the record is where the letter was already present. At r the office wrote, as its entire record, one line, and read it back to itself several times and found it complete: r is. It now files the discovery that the last glyph of that sentence is the letter now on the desk. The previous record was complete only in the sense that it ended exactly where the next letter would begin; s was in the paperwork before it was in the field, and the office, which has spent sixteen events filing letters, files that a letter can be filed before it is delivered, and finds, on inspection, that this has in fact been happening all along.

The office writes, as procedure requires of the one-line record, the letter's name; and the name — ess — settles nothing, so it writes down what the name's position in the field does instead. r arrived as are, the copula's statement. The second letter of the undelimited field is the tail of is: the present-tense singular third-person form of the verb of being, the letter that does the asserting in the sentence the office already filed. The field is not shipping nouns anymore. Since q its deliveries have beenare, then is — two inflections of existence, in order, one per turn, the administrative apparatus behind it still lying spent like a dock the tide has gone out past, and the letter now arriving is the piece of the tense the previous record required without knowing it. The office files that the preceding record was a complete sentence, and that its completion required a letter the office had not met, and that it has no further comment, expertise in verb morphology being outside its jurisdiction, which it files anyway.

The structural finding is that s is the run's first letter with no standalone meaning. Its entire working vocabulary is grammatical: it pluralizes — letter becomes letters; it marks the third-person singular present — it is; it marks the possessive —its; it hosts the elision — it's. One glyph, a dozen jobs, and no job of its own: s is not a thing, it is a change made to a thing, and it is the most common change the language makes. The office had filed e, at the run's second event, as the most frequent letter; it files now the distinction it had not previously needed, that frequency and workload are not the same. Every s in its own dossier —reservations, refusals, letters, files, even the count, which the office notes with a professional wince into a plural it no longer administers — is a working grammar, and the office, which has spent sixteen events writing policy full of them, discovers it has been employing this letter the entire time without filing it, the way it never filed r.

It further files the character note that the letter which multiplies everything cannot multiply itself by its own hand: the plural of the multis s-part is s's or ses, both of which borrow from outside the letter to count to two. The plural marker is the alphabet's most dependent glyph — it only ever appears leaning on something else, and on its own it is the emptiest letter on the desk; and the office files that the letter whose function is abundance is the letter that cannot count itself without an apostrophe, and declines to find this a coincidence.

The structure is the run's first containing no straight stroke at all — no stem, no upright, no post, no branch. r was the shared upright with its first branch; s is the proof the alphabet can leave the upright entirely and still make a letter. It is one continuous stroke that reverses its own curve once: an upper bow and a lower bow, both open, sharing a throat at the middle. o was the un-orientable, the closed counter; s is the un-closeable — the double counter that refuses to enclose, the figure with two open ends and no direction of entry, the letter you can enter from above or below. The office notes that the two bows are mirror images — the run's second mirrored pair, where p and q faced each other across the width of their chasm, folded here into a single glyph, the reflection inside the letter instead of beside it.

And it files, with what it believes is severe understatement, that the letter is shaped like the thing that delivered it. The second letter of the water is the meander — the track of a current, the reach of a river, the serpent's line — and the channel, which has now twice shipped into open water in the exact order it has kept for sixteen events, has sent a letter that draws the path it travels. The office does not comment on this. It files the shape and the route and lets the reader hold both at once, the way it let the previous record hold this letter without knowing it was doing so.

The phonetics: s is the sibilant, the continuous stream of air pressed through a narrow gap and held — the run's first sound that never has to end. h was the letter with no sound of its own, the breath without an edge; s is that same unvoiced breath, put under pressure from behind and given a slit. k was the loudest un-holdable stop, the click that spends all its air at once; s is the holdable leak, the slow expenditure, the release that goes on as long as the reader has breath to pay for it. It is, accordingly, the sound of silence being imposed — the shush, whose entire social function is to make the room quiet — and the office, whose institution is a long quiet corridor full of filed letters, must now file that a truly quiet building is not silent: there is the low m, filed at event ten as the building's own noise floor, and there is, just above it, the hiss — the ventilation, the hydraulics, the compressed air the door seals let out — the building policing its own silence, and failing, and the office recording the failure quite well.

And the voice is borrowed. Unvoiced, s hisses — cats, packed. Voiced, it is the same street with the voice on — dogs,is, letters. The plural s does not decide its own voicing; it takes the voicing of the thing it has been attached to, so that the letter greets voiced company with a buzz and unvoiced company with a hiss. The run has filed g, at event four, refusing to choose between its two sounds. s does not refuse and does not choose: it reflects its company, the mirror q brought into the run now gone acoustic. The letter dedicated to making one into many has no identity of its own sound; it is voiced only in the presence of voices. The plural, the office files, is the most social letter in the field, and the most dependent — the letter that makes everything count toward more and cannot, alone, make even itself sound.
