Jackal-headed god (6)
I believe the answer is:
anubis
'jackal-headed god' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anubis that I've seen before include "Is a bun about the ancient Egyptian god of the dead" , "Egyptian god - in a bus (anag)" , "Jackal-headed deity" , "one Egyptians thought great" , "Egypt. jackal-headed god" .)
