Yes and it lives up to that promise. This article says English is "easy" but Esperanto is so much easier you can learn it for free along the way of learning English. For an overview: https://en.wikipedia.org/wiki/Propaedeutic_value_of_Esperanto https://en.wikipedia.org/wiki/Propaedeutic_value_of_Esperant... And a recent experiment: https://ec.europa.eu/programmes/erasmus-plus/projects/eplus-project-details/#project/2017-1-HR01-KA201-035396 https://ec.europa.eu/programmes/erasmus-plus/projects/eplus-... > The tests were completed by the pupils who learned Esperanto and a control group of equal size and same previous language learning experience, who did not. They showed that the children who participated in Multilingualism Accelerator classes had considerably higher scores than those who didn't.
