Fundamento de Esperanto

The "Fundamento de Esperanto" ("Foundation of Esperanto") is a book by L. L. Zamenhof, published in the spring of 1905. On August 9, 1905 it was made the official source for the language by the fourth article of the Declaration of Boulogne at the first World Congress of Esperanto in Boulogne-sur-Mer, France. It is considered the only obligatory authority over Esperanto and is thus unchangeable.

The "Fundamento" consists of four parts: a Foreword ("Antaŭparolo"), a Grammar ("Gramatiko"), a collection of exercises ("Ekzercaro") and a "Universal Dictionary" ("Universala Vortaro"). With the exception of the Foreword, almost everything in the "Fundamento" comes directly from Zamenhof's earlier works.

Equal to the "Fundamento" are the "Official Additions" ("Oficialaj Aldonoj"). To date, there have been nine Official Additions. The Foreword of the "Fundamento" states:

The grammar and dictionary sections of the "Fundamento" are in five national languages: French, English, German, Russian, and Polish.
