Etymology
Proposed to be derived from Proto-Yoruboid *à-ɓã. A distinctive marker of Proto-Itsekiri-SEY from Proto-Yoruba is the lack of differing second and third person plural pronouns. This distinction continues in the present in Itsekiri and amongst all Southeast Yoruba varieties except Ìjẹ̀bú, which uses ẹ̀wẹn and ọ̀wọn, respectively. Cognates include Itsekiri àghan, Yoruba àwọn, Ìjẹ̀bú Yoruba ọ̀wọn, Ifè àŋa, Igala àma, Olukumi àwan, Àhàn xà, Èkìtì Yoruba ìn-ọn
