Ulwaluko, traditional circumcision and initiation form childhood to adulthood, is an ancient initiation rite practised (though not exclusively) by the amaXhosa, and is commonly practised throughout South Africa. The ritual is traditionally intended as a teaching institution, to prepare young males for the responsibilities of manhood. Therefore, initiates are called abakhwetha in isiXhosa: aba means a group, and kwetha means to learn. A single male in the group is known as an umkhwetha. A male who has not undergone initiation is referred to as inkwenkwe (boy), regardless of his age, and is not allowed to take part in male activities such as tribal meetings.
