what does ofoni mean in urhobo

Wrong line of argument. We have many Urhobo towns and villages whose meanings have been lost. You should also know that some Urhobo towns in Delta State have Ijaw heritage as well yet they are not Urhobo. Many historians argue that some kingdoms in Eastern Urhobo have Mein or Tarakiri heritage but they all identify as Urhobo because that's what they are. Ofoni people may also have Tarakiri heritage but make no mistake about their Urhoboness. If any Ofoni person calls himself an Ijaw, it is simply out of political expediency. There are many Urhobos that do same in Delta by identifying as Itsekiri or Ijaw to get NNPC, CHEVRON or SHELL jobs.
