Tagati
In South African English, a tagati is a wizard, witch, or a spiteful person who operates in secret to harm others or who uses poisons and familiar spirits to carry out harmful deeds. The term is first recorded in 1836; it derives from the Zulu word umthakathi, being someone who mixes medicine. The word umthakathi (plural abathakathi) itself comes from two Zulu words thaka (mix) and muthi (medicine).
