Fundamento de Esperanto (Foundation of Esperanto)

by L. L. Zamenhof

Summary

L. L. Zamenhof's *Fundamento de Esperanto* establishes the language's unchangeable core—the grammar, framework, and root words in a single small book—as a "fundamental document" that no one has the right to alter, even if it contains errors. This strict inviolability preserves unity and user confidence, preventing the language from becoming "one thing to-day and another thing to-morrow." However, Zamenhof explicitly allows for "gradual perfection" through a central institution with indisputable authority, which can augment the Fundamento by adding new words or rules, but never change the existing fundament. Until such an institution acts, any good material not in the Fundamento is only recommended, not compulsory.

The book presents the Fundamento as a constitution securing Esperanto's future, with enough root words for ordinary ideas. A reader learns that the language's stability depends on this dogmatic foundation, which Zamenhof justifies as practical self-restraint after years of refinement. The work also addresses objections to international languages, classifying them to show their mutual destructiveness. The takeaway is that Esperanto's design balances an inviolable base with cautious, centralized evolution, ensuring it remains a reliable tool for international communication.
