The international auxiliary language Esperanto has been mostly stable since its creation, especially as compared to other constructed languages. This is due to the Declaration of Boulogne in 1905, which made the early works of Zamenhof binding; most attempts to change the language have been therefore seen as distinct language projects (so-called Esperantidos), and for the most part the Esperanto community has ignored them. The main change in the language has been a great expansion of the vocabulary, largely driven by translations of technical jargon, which is explicitly allowed for by Boulogne. However, there have been more subtle changes to syntax and semantics as the majority of Esperanto authors shifted from native speakers of Slavic languages and German to other languages, such as French and English.[a] This article considers some of the purposeful changes to the language since Boulogne.
