Nggàm
Nggam is a type of divination found among many groups in western Cameroon. Among the best documented is its practice by the Mambila people of Cameroon and Nigeria, in which the actions of spiders or crabs are interpreted by the diviner: see Zeitlyn 1987 and 2020. The form used by the neighbouring Yamba people was described by Gebauer in 1964 based on experience in Mbem going back to before 1939, and more recently by Hermann Gufler.
The comparative linguistics of spider divination in Cameroon was surveyed by Blench and Zeitlyn in 1989/1990.
