The name Singo is part of the big five animals, from the elephant (Ndou). It is part of the aboriginal Mbedzi of the Venda/Kalanga clans. The Matabele found the Singo king ruling the area. The present Venda rulers (Singo) took the name which they found in the area late 17 century.
It is now that the aboriginal Singo are swallowed by the Ndebele in the present Zimbabwe and also swallowed by the rulling Singo in Venda. In the begining the Venda and the Kalanga were one and the same people living in both the Venda and Vhukalanga countries before the colonizers, who make Limpopo (Vhembe) river as the border between the present Zimbabwe and South Africa of today.
