Explanation

Igbo names carry meaning. Many reference Chi (personal god/destiny): Chukwuemeka (God has done well), Chinonso (God is close), Chidinma (God is good). Names express circumstances of birth or family aspirations.

Other name types: day of birth (Nkwo, Eke, Orie, Afo), circumstances (Onwueme – death occurs), gratitude (Ndidi – patience), family position (Ada – first daughter, Okpara – first son).

Naming ceremony (Igu Aha) occurs about a week after birth. Father or elder names the child. Names may accumulate through life – titles, praise names, nicknames. Names tell stories.
