Ido is a constructed language, a so-called reformed Esperanto, which was developed in 1907. Ido was made by a group of people that thought Esperanto was too hard to be a world language. They did not like how Esperanto used letters with special diacritic marks over them, because that made it hard to type, and they thought that a world language should be easy to learn and write.
