Cognates include Itsekiri àghọ̀fẹn, Ìjẹ̀bú Yoruba àwọ̀fi. Proposed to be derived Proto-Yoruba *à-wɔ̀fɪ̃, from Proto-Edekiri *à-ɣɔ̀fɪ̃. The Proto-Yoruboid term is unclear, see Igala éfọfẹ (“palace”), Igala ọ́fẹ (“chieftaincy title”). Here we see a shifting of /ɣ/ and /w/ to /f/ or vice versa, which, while it is not clear which direction that sound change may have taken, is seen in other Yoruboid or Edekiri cognates, see ehoro vs. afolo and ọ̀fàfà vs. awàwà. See perhaps ultimately from Proto-Yoruboid *á-fɔ̀fɪ̃, *ɛ́-fɔ̀fɪ̃ or Proto-Yoruboid *á-ɣɔ̀fɪ̃, *ɛ́-ɣɔ̀fɪ̃. Also see Proto-Yoruboid *-fɪ̃ (“root relating to royalty or nobility”). Likely a Doublet of Ọlọ́fịn, Doublet of ọfịn, Doublet of Ọ̀dọ̀fin
