Tadibya (tádyebya; Russian: тадебя) is the mediator between the ordinary world and the upper- and underworlds of the spirits among the Nenets people. The Nenets rank their shamans by their spiritual attachment and function as well as their experience.
The following categories of Nenets shamans are listed by Mihaly Hoppal, who cites research conducted by L. Khomitch and Leonid A. Lar.
