Particularly this part of the chorus, I’m unsure how best to transcribe it. My mentor Professor Keita sent me this transcription/translation in French:
N’alouw(ô mes mères), Di’ala salouma(je vous dis), sinaya la gwèlèya magni (la rivalité de la polygamie est pénible), a ma silan ni (et effroyable)
I ni ce, Bruce! I’ve added your request to the Request song lyrics category, so perhaps someday we’ll get there
In the meantime, I had a look at Professor Keïta’s transcription/translation and I had a listen to the song’s chorus. So, thank you to Keïta-kɛ, because without his initial work, I wouldn’t have been able to hear it correctly.
Here’s what I would propose for standard Latin-based spelling (I have also included a very literal translation for you):
Nalu [OR: N nalu (Keïta proposes this, but I don’t necessarily hear the N)]
Mothers [OR: ‘My mothers’]
N di à lase alu ma
I transmit to you (the following)
Sinaya la gbɛlɛya man ɲi [OR: Sinaya la gbɛlɛya ma ɲa]
The hardship(s) of co-wifehood isn’t good
It seems like it could work, except I’d take issue with your use of “problems between co-wives” for sinaya la gbɛlɛya (cf. sinaya ka gɛlɛya in Bambara), which is more literally ‘the difficulty of co-wifehood’.
To me, this could suggest that the chorus is about if/when problems happen to come up in polygamous wifehood situations. But instead I think that that the turn of phrase is actually a more blanket statement about co-wifehood being difficult in a way by nature.
