Shem the first time I came across the terms was in Black Man of the Nile many decades ago. Jochannon mentioned that was the oldest term for Africa or I would suggest signficant parts of it. Because to my knowledge there has never ever been a prevailing and shared name for the whole continent as regional and geographical identities were more stronger if we move beyond kinship and clan as organising principles.

Personally then and now I do not see much value in reusing those terms even if they were widely shared which I do not believe they were actually. Labels have to be lived in and through for them to be real and form the basis of identity on any meaningful level and in the specific one you cite shared through common or similar languages.

So that is a leap to big for me to make and even more fragile for me to intellectually defend or advance.

Peace.
