The Jarawan Bantu
languages form a closely related cluster,
stretching from Northern Cameroun, into Adamawa and across into Plateau and Bauchi
They are very
closely related to Bantu, indeed to the A60 languages and they have only not been treated as Bantu because their nominal prefixes are now frozen
possibly due to
contact with Chadic.
However, on lexical
grounds they should be treated as Bantu proper. Their exclusion is typological rather
than genetic
But of course this
does not explain the motivation for their extraordinary migrations..
Ekoid in SE Nigeria
represents another early movement westwards from the Bantu heartland
