Word on the street is that the Pygmys speak Bantu languages of the surrounding Congoid/Bantu majority.
But did the Pygmy’s have their own original language? Surely they must, if they had speech, since there had to have been divergent evolution between Bantu and Pygmy. But then, what was that language? Might it have been (to us) extremely unsual in its features? If it’s lost, have the linguists reconstructed it from the few surviving words?
(PS I know that there are more than one nation/group/race of Pygmys, i’m lumping them in together for efficiency purposes)
