Etymology
Cognate with Edo ùghà, Itsekiri ùghà, probably ultimately from Proto-Edekiri *ʊ̀-ɣà, but also possibly an Edo loan word. Also see Proto-Yoruba *ʊ̀-ɣà. The palace of the Oba of Lagos is known as ìgà, which may suggest this term is likely an Edo term, perhaps borrowed into Proto-Edekiri or a later stage of Yoruba.
