Southern Bantoid (or South Bantoid), also known as Wide Bantu or Bin, is a branch of the Benue-Congo languages of the Niger-Congo language family. It consists of the Bantu languages (also called Narrow Bantu) along with several small branches and isolates of eastern Nigeria and west-central Cameroon (though the affiliation of some branches is uncertain). Since the Bantu languages are spoken across most of Sub-Saharan Africa, Southern Bantoid comprises 643 languages as counted by Ethnologue, though many of these are mutually intelligible.
The unity of the North Bantoid group was subsequently called into question, and Bantoid itself may be polyphyletic, but the work did establish Southern Bantoid as a valid genetic unit, something that has not happened for (Narrow) Bantu itself.
According to Williamson and Blench, Southern Bantoid is divided into the various Narrow Bantu languages, Jarawan, Tivoid, Beboid, Mamfe (Nyang), Grassfields and Ekoid families. The Bendi languages are of uncertain classification; they have traditionally been classified with Cross River, but they may actually be Southern Bantoid. Blench suggests that Tivoid, Momo (ex-Grassfields) and East Beboid may form a group, perhaps with the uncertain languages Esimbi and Buru:
