The Greek that is typically translated/transliterated in English as “demon” is translated in Central Mazahua as “the evil spirit(s) of the devil” (source: Ellis Deibler in Notes on Translation July, 1967, p. 5ff.).

In Sissala it is translated with kaŋtɔŋ, which traditionally referred to “either a spirit of natural phenomena such as trees, rivers, stones, etc., or the spirit of a deceased person that has not been taken into the realm of the dead. Kaŋtɔŋ can be good or evil. Evil kaŋtɔŋ can bring much harm to people and are feared accordingly. A kaŋtɔŋ can also dwell in a person living on this earth. A person possessed by kaŋtɔŋ does not behave normally.” (Source: Regina Blass in Holzhausen 1991, p. 48f.)
