Ọmọ Onilẹ is a Yoruba phrase that literally means children of the land owner. The phrase is usually used to refer to people who have inherited large parcels of land and are in the business of selling land.
Ọmọ Onilẹ is also sometimes used as a derogatory term to refer to people who unscrupulously collect illegal taxes from land purchasers who have just bought a piece of land or house in some areas.
