Languages within a family are supposed to share similarities at different levels of grammar as clear evidence of their genetic relationship. The four Nigerian Languages studied in this paper: Yoruba, Ebira, Igede and Ukaan are according to scholars genetically related. One expects on account of this to see areas of similarity as evidence of the relatedness. In this paper, we present morphological evidence that suggests that the languages must probably have been related in the distant past.
