Igbos like every other tribe in Nigeria have slight and deep differences in language.I travelled to Ekiti and parts of Ondo state in 2007 and never understood what they were saying. despite my understanding of Yoruba.The Waawa clan of Northern Igboland, also referred to as Ndi Waawa, Wawa People, are a unique sub-group of the Igbo people in Enugu State, Nigeria, consisting of several communities, who all speak a unique dialect of Igbo called Waawa. The most notable among these are the Agbaja and Ngwo which consist of peoples between the wooded lands of Awka (capital of Anambra State) to the rocky valleys of Enugu (capital of Enugu State). The Agbaja are made up of communities in present-day Ngwo clan, Udi, Ezeagu, Igbo-Etiti, Oji River, greater Awgu, and Enugu East Local Government Areas. Other notable parts of the Waawa clan include Nkanu, Nsukka, Abia (not be confused with people from Abia State), Nike,and other communities in Enugu State. The Waawa are most notably associated with Chief Onyeama of Eke, who was the paramount ruler of Agbaja in the early 20th Century.
