He was worshipped in some foreboding (4)
I believe the answer is:
odin
'he was worshipped' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'in some foreboding' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ODIN' can be found hidden inside 'some foreboding'.
Can you help me to learn more?
(Other definitions for odin that I've seen before include "Legendary ruler" , "The supreme Norse god and creator" , "Legendary Scandinavian" , "who's worshipped" , "Pagan god" .)
