What language was developed from Esperanto?

Esperanto is a constructed language, not a natural language. This means it was specifically designed, rather than evolving organically like English or Spanish. As a result, Esperanto doesn't have any "descendants" in the same way a natural language might.

However, Esperanto has influenced the development of other constructed languages, including:

* Interlingua: While based on Romance languages, Interlingua borrowed some features from Esperanto, like its simplified grammar and vocabulary.

* Ido: This language was created as a reform of Esperanto, aiming to address some perceived flaws in the original.

* Volapük: While older than Esperanto, Volapük was influenced by its success and led to its own reform movement.

Therefore, it's not accurate to say Esperanto developed from another language, but rather that its influence can be seen in other constructed languages.
