ikin noun /ī.kĩ̄/ spelling unconfirmed
Definitions
  1. sacred palm nuts that are used as divination tools in the consulting of Ifa by babalawos. The using of the ikin is reserved for highly important ceremonies (such as during a Àkọsẹ̀jayé) and is how priests determine the signature of an odù Ifá.
    The ọ̀pẹ̀lẹ̀ and ẹ̀rìndínlógún both serve similar purposes, with the ọ̀pẹ̀lẹ̀ being used for less formal situations and the ẹ̀rìndínlógún being used by aborisha that are not initiated into Ifá.
