# Ancient Web: Pilish Turns the Digits of Pi Into English Prose The Cadaeic Pilish page explains a constrained-writing system where successive word lengths encode the digits of pi, including rules for zeros, long words, punctuation, and extended compositions that hide mathematics inside readable prose. 2026-09-02 :: Switchboard Tech Services ![Ancient Web: Pilish Turns the Digits of Pi Into English Prose](https://switchboardtechservices.com/static/images/defaults/articles.webp) Part of the [Ancient Web Collection](https://switchboardtechservices.com/articles/ancient-web-collection/). Some people memorize pi with a song. Others apparently decide English itself should be forced to carry the digits. [Visit the Pilish page](https://www.cadaeic.net/pilish.htm) Pilish is a constrained form of writing where the length of each word encodes the successive digits of pi. The classic example begins with words of lengths 3, 1, 4, 1, 5, 9 and so on. That works until the decimal expansion produces a zero, because ordinary prose does not contain zero-letter words. The page's solution is wonderfully practical: let a ten-letter word represent zero. ## Writing inside a numerical cage The site distinguishes Basic Pilish from Standard Pilish. In Basic Pilish, words shorter than ten letters represent their literal length and ten-letter words represent zero. Standard Pilish adds a rule allowing words longer than ten letters to encode two consecutive digits. A twelve-letter word, for example, can represent 1,2. That sounds like a tiny technical adjustment, but it gives writers much more freedom. The page also defines how apostrophes, hyphens, punctuation, and numbers should be treated so that a text can be decoded consistently. In other words, Pilish is not merely a party trick. Somebody cared enough to write a specification. The result is a peculiar hybrid of mathematics, mnemonics, and constrained literature. A normal writer asks which word best fits the sentence. A Pilish writer also has to ask whether that word has exactly the right number of letters for the next digit. That changes composition at a very low level. Syntax, vocabulary, punctuation, and even subject choice bend around the constant. The site points to longer works built under these rules, including *Cadaeic Cadenza* and *Not A Wake*, where the constraint becomes nearly invisible unless the reader starts counting. Pilish may be one of the purest examples. It is what happens when a mnemonic becomes a literary genre.
