Something I'm working on in regards to the Kung.
The Kung concept of num correlates in many respects with the Dogon concept of Nommo. nommo even shares the same consonantal root (n-m-m) with num (n-m), Nommo is the life force which produces all life and influences 'things' in the shape of the word. Nommo can be seen as the divine Logos of the Greeks. The great Dogon sage Ogotommeli states that Nommo is 'water and heat'. The vital force that carries the word issues from the mouth in a water vapour which is both water and word (Griaule 1948: 165). Nommo, therefore, is water and the glow of fire and seed and word in one (Jahn 1961: 124). It is my contention that the words num and Nommo ultimately derive from words that mean "water" and fire" as they are both seen in Africa as the sources of all life and vitality.

The element of water is often seen as "spirit" in African traditions. the human being's true essence is spirit and it is formless and genderless like water. The numerous variations of water, with the -n- root, render as spirit or soul in many African languages with a slight alteration of vowels.

OAN :
Nyama (n-m), like Nommo (n-m-m) among the Dogon, is also associated with the power of the word (Doumbia & Doumbia, 2004: 33-4) and is associated with Bards : the master story tellers who are the keepers of ancient knowledge. In S. Africa townships, the phrase shisa nyama describes an informal barbeque where friends meet near a butchery and grill meat in open fire. Nyama Choma in Kiswahili is the term for "roasted meat" which is also a term used for open barbeques in Kenya among the Massai
