Not DRC, I'm talking about...
But otherwise yeah thats pretty much the region I was expecting.
I caught the french pretty easy I just wasn't sure where the rest came from. It could be french based with some nouns from an African language. I watch a lot of Nigerian movies in English and they still use a lot of Igbo terms even though the majority is in English. You can usually catch what the term means by the context in which it's repeatedly used though ....it took me a min to get what the hell "igwe" meant

(I kept thinking it meant "hello" at first

)
That said I went with Congo because in studying Dr. Fu-Kiau Bunseki's(who actually was from DRC) works around my palo mayombe studies I found a lot of "Bantu Congo area" terms like N-ganga, N-fumbe, N-tanga, M-bungi, Ki-kongo, Di-kenga, etc etc
I saw a lot of words like that in the videos also which is why I started my search around that region.

...even with your name mbewane I would start my guess in a circle around Angola, Camaroon, CAR, DRC ....then expand to other African countries if I were looking to find where that name comes from.
