InDuna (plural: izinDuna) is a Zulu title meaning advisor, great leader, ambassador, headman, or commander of group of warriors. It can also mean spokesperson or mediator as the izinDuna often acted as a bridge between the people and the king. The title was reserved for senior officials appointed by the king or chief, and was awarded to individuals held in high esteem for their qualities of leadership, bravery or service to the community.   The izinDuna would regularly gather for an indaba to discuss important issues.
The term has found widespread use in South African English and Afrikaans, and it is a common reference to boss or lead person.  In modern times the terms Chairperson and inDuna are sometimes used interchangeably.
