Pilish

Pilish is a constrained writing style where the length of each word must correspond to the digits of pi (π). The most common implementation uses the first several digits of pi: 3.1415926535... meaning the first word has three letters, the second has one, the third has four, and so forth.

The term "Pilish" refers to both the act of writing in this way and the resultant text itself. It is considered a form of constrained writing, similar to lipograms or palindromes, placing artificial limitations on word choice and sentence structure.

While the challenge lies in adhering to the pi sequence, the goal is typically to create a coherent and meaningful text, rather than just a string of words conforming to the numerical pattern. Skilled Pilish writers aim to construct narratives or express ideas, showcasing creativity within the self-imposed rules. The length of the Pilish text depends on how many digits of pi are used.

Pilish is often seen as a recreational linguistic exercise or a mathematical curiosity, demonstrating the interplay between language and mathematics. The difficulty increases exponentially with the length of the text and the desire for semantic coherence.
