oli-

Etymology
From. The "o" prefix harmonizes with the initial vowel associated with the noun it precedes. Because /n/ and /l/ are allophonic, both oní- and olí- are essentially the same, and in Standard Yoruba, oní- will often have an /l/ when in compounds. However, in certain dialects, the /n/ and /l/ are not allophonic in this case, /l/ is primarily used like in Egba and Ekiti, while in Ondo or Ijebu, only /n/ is used.

Usage notes

 * In Oǹdó, the "o" is deleted.
