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.

Some people memorize pi with a song. Others apparently decide English itself should be forced to carry the digits.
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.
