Cognate with Urhobo eni, Edo ení, Igbo enyi, Igala éli, Olukumi erin, in many cognate languages, this form was replaced by a form seen in Nupe dagba, Idoma adagba, Igala adagba. Proposed to be derived from Proto-Yoruboid *é-lĩ or Proto-Yoruboid *é-nĩ. See Benue-Congo cognates, Ibibio eniin, Tee ni, Proto-Lower Cross River *é-nì:n, Proto-Ogoni *ǹnĩ, Westerman constructs a possible reconstruction to Proto-Atlantic-Congo *-ni-, and also suggests that it probably is of the same root as the root for four, thereby being a distant Doublet of ẹ̀rin
