Mythical creator of some foreboding (4)
I believe the answer is:
odin
'mythical creator' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'some foreboding' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ODIN' is hidden in the letters of 'foreboding'.
'of' is the link.
Can you help me to learn more?
(Other definitions for odin that I've seen before include "King of Norse gods" , "Scandinavian war god" , "Mythological Norse god of war" , "Chief Norse god" , "God - I nod (anag)" .)
