Thor's father (4)
I believe the answer is:
odin
'thor's father' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for odin that I've seen before include "who's worshipped" , "The supreme Norse god and creator" , "Legendary Scandinavian" , "Norse god, husband of Frigg, father of Thor" , "Chief god of Scandinavian myth" .)
