This video explains how single words in Swahili are constructed from many different parts: The Swahili Language
My conclusion was that it must be much easier to learn that when one can speak Esperanto well, especially advanced Esperanto, including the construction of more complicated terms.
Can you confirm this?
Edit: I guess there are probably no studies around, but has anyone learned Esperanto first and then Swahili? (Duolingo might be able to find out once the Swahili course is in beta).
