n. a Yoruba chieftaincy title that denotes a Priest of Ifá
Wikipedia
Babaaláwo or '''Babalawo (Babalao '''or Babalaô in Latin America; literally meaning 'father of the mysteries' in the Yoruba language) is a spiritual title that denotes a Priest of Ifá. Its female counterpart is called Iyalawo (meaning 'mother of divination) or Iyanifa (Mother of Ifa). Ifá is a divination system that represents the teachings of the Orisha Orunmila, the Orisha of Wisdom, who in turn serves as the oracular representative of Olodumare. The Babalawo ascertain the future of their clients through communication with Ifá. This is done through the interpretation of either the patterns of the divining chain known as Opele, or the sacred palm nuts called Ikin, on the traditionally wooden divination tray called Opon Ifá.
