A brooding god? (4)
I believe the answer is:
Here is my best explanation:
'god?' is the definition.
(Odin is an example)
'a brooding' is the wordplay.
'ODIN' is hidden within the letters.
But, I am not sure how this is indicated.
(Other definitions for odin that I've seen before include "Supreme Scandinavian god and creator", "Pagan god", "Mythological Norse god of war", "Supreme god of war in Norse mythology", "Legendary Scandinavian", "an all-powerful one", "Chief god of Scandinavian myth", "Old Scandinavian", "God - I nod (anag)" and "Supreme god of Scandanavian myth".)
