Ulwaluko
Ulwaluko, traditional circumcision and initiation into manhood, is an ancient initiation rite practised by the amaXhosa. 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.
