What is Ido and how is it different from Esperanto?

Ido was created in 1907 by the Delegation for the Adoption of an International Auxiliary Language as a reform of Esperanto. The name means 'offspring' in Esperanto. Compared to Esperanto, Ido drops the diacritics (no ĉ, ĝ, ĥ, ĵ, ŝ, ŭ), uses fewer obligatory accusative endings, has stricter rules for word formation, and replaced some roots felt to be too 'European' biased.

How many people speak Ido?

Estimates of active Ido speakers range from a few hundred to several thousand worldwide. The community is small but maintains the Uniono por la Linguo Internaciona Ido (ULI) and regular online meetings. While not as widely used as Esperanto, Ido has a published literature including translations of Shakespeare and Andersen and is documented in the official Kompleta Gramatiko Detaloza.
