Vendergood: Reconstructing a 1905 constructed language for AI agent cognition
A new project aims to reconstruct and extend Vendergood, a constructed language created by William James Sidis. The initiative seeks to fill in gaps in the language's historical record while adhering to Sidis's original design principles. New vocabulary and grammatical rules are being added to make the language usable in modern contexts.
- ▪Vendergood was originally created by William James Sidis when he was just seven years old.
- ▪The reconstruction includes a twelve-mood system and new vocabulary entries with etymology and usage examples.
- ▪The project is open for contributions, allowing others to add new words and grammatical extensions.

Opening excerpt (first ~120 words) tap to expand
libro-vendergood A reconstruction and extension of Vendergood, the constructed language of William James Sidis (1898–1944), with new vocabulary added for modern use. Sidis wrote the Book of Vendergood at age seven. The book is lost to public archives; what survives of the language is sparse — biographical mention of eight verb moods, base-12 numerics, Latin and Greek roots, a "more complex than a Japanese verb" gender system. The historical record is enough to know that Sidis was building something structurally serious, and not enough to use the language as it stands. This repository is an attempt to finish what survived. Documented choices are followed exactly. Gaps are filled by inference from Sidis's design principles. Extensions are marked.
