However, in the early twentieth century numerous reform projects were proposed. Almost all of these Esperantidos were stillborn, but the very first, Ido ("offspring"), had significant success for several years. Ido was proposed by the Delegation for the Adoption of an International Auxiliary Language in Paris in October 1907. Its main reforms were in bringing the alphabet, semantics, and some grammatical features into closer alignment with the Romance languages, as well as removal of adjectival agreement and the accusative case except when necessary. At first, a number of leading Esperantists put their support behind the Ido project, but the movement stagnated and declined, first with the accidental death of one of its main proponents and later as people proposed further changes, and the number of current speakers is estimated at between 250 and 5000. However, Ido has proven to be a rich source of Esperanto vocabulary.
