A rite of public confession and enquiry held during the Kundum festival, in which the community's grievances and wrongdoings are brought into the open before the deities and the chief. It functions as an annual clearing of accounts between people and between people and the gods. Related observances are found among the Ahanta and in Côte d'Ivoire as Abissa.
Abisa allows a townsperson to speak plainly to the chief without reprisal.
