High Quality Content by WIKIPEDIA articles! Esperantido is the term used within the Esperanto and constructed language communities to describe a language project based on or inspired by Esperanto. Esperantido originally referred to the language of that name, which later came to be known as Ido. The word Esperantido is derived from Esperanto plus the suffix -ido (a descendant). Thus, "Esperantido" literally means "an offspring of Esperanto".
