The Ndut is a rite of passage as well as a religious education commanded by Serer religion that every Serer (an ethnic group found in Senegal, the Gambia and Mauritania) must go through once in their lifetime. The Serer people being an ethnoreligious group, the Ndut initiation rite is also linked to Serer culture. From the moment a Serer child is born, education plays a pivotal role throughout their life cycle. The ndut is one of these phases of their life cycle. In Serer society, education lasts a lifetime, from infancy to old age.
The name Ndut comes from the language of the Ndut people, a sub-group of the Serer people. In a religious sense, it means nest. It is a place of sanctuary, and the place where Serer boys lodge in preparation for their circumcision. These boys are called njuli (initiates). The word njuli comes from the Serer word juul (variations : juu) which means a little boy's penis. Because of its religious connotations, the word has been borrowed by the Wolof to designate a Muslim person (juulit) (see :Serer religion's influence in Senegambia).
There are two main types of Ndut initiation rites. The first concerns the circumcision for Serer boys whilst the second concerns the initiation of Serer girls. Serer religion and culture forbids the circumcision of Serer girls (Female genital mutilation). Only Serer boys are circumcised. Serer girls receive their initiation through njam or ndom (the tattooing of the gums). Preparation for the initiation starts early in childhood. In many cases, boys are circumcised when they reach 13 years old. However it is not uncommon for some to be circumcised when they are 19 to 26 years old. Likewise, Serer girls receive their initiation when they are 11 to 18 years.
