Irosun

Possibly, but unlikely from ìròsùn (“camwood”). Cognate with Idoma Orosu, Itsekiri Ùròsùn, Igala Òlòrù, Edo Òrúùhù, Urhobo Ùɹ̝̊ùɹ̝̊ù, Igbo Ùrúrù, Igbo Ùlúshù, Nupe Rùsù, Ebira Òròsù, Fon Lósò. Proposed to be derived from Proto-Yoruboid *ò-lòsũ̀, it has remained consistent across Volta-Niger, with the exception of the variation between /s/, /r/, and /h/, a common occurrence. Perhaps ultimately from a root similar to Proto-Volta-Niger *-lòsù

IPA^(key): /ì.ɾō.sũ̀/, /ì.ɾò.sũ̀/
