Reformed Esperanto was a reformed version of Esperanto created in 1894. It is notable as the only complete Esperantido to have been created by Esperanto's original creator, Dr. Zamenhof. Although Zamenhof's stated preference was to avoid any discussion of changes, he was put under considerable pressure (including financial) to respond to the diverse reforms proposed by others. Reluctantly he decided to present a reformed dialect himself and undertook to continue guiding the community, whether or not reforms were eventually agreed. As a recently constructed language, Esperantos history is short and relatively well-known. ... 1894 was a common year starting on Monday (see link for calendar). ... Esperantido is the term used within the Esperanto and constructed language communities to describe a language project based on or inspired by Esperanto. ... L. L. Zamenhof Dr. Ludovic Lazarus (Ludwik Lejzer, Ludwik Łazarz) Zamenhof (December 15, 1859–April 14, 1917) was an ophthalmologist, philologist, and the initiator of Esperanto, the most widely spoken constructed language. ...

Although Zamenhof initially called his reform a systematic attempt to re-create the language in the light of more than six years of practical experience, scarcely any of the Esperanto community of the time accepted it as a whole. The majority voted to reject all changes. Zamenhof himself later rejected the whole project and referred to 1894 as 'a wasted year'.

Some of the proposed reforms from 1894 such as replacing the -oj plural with -i, the removal of the diacritics and adjectival agreement were used in the language reform project Ido beginning in 1907, but these were not accepted by the Esperanto community either and Esperanto has changed relatively little since the publication of Zamenhof's Fundamento de Esperanto in 1905. Ido is a constructed language, arguably the second-most used International Auxiliary Language in the world. ... 1907 (MCMVII) was a common year starting on Tuesday (see link for calendar). ... 1905 (MCMV) was a common year starting on Sunday (see link for calendar). ...
