A deity from the North originally (4)
I believe the answer is:
thor
'a deity' is the definition.
(Thor is an example)
'from the north originally' is the wordplay.
'from' indicates the answer is hidden within the clue.
'THOR' can be found hidden inside 'north originally'.
(Other definitions for thor that I've seen before include "Germanic thunder god; early US IRBM" , "Thursday is named after this Scandinavian god" , "Scandinavian god of thunder and the weather" , "Norse god of war" , "Norse god for whom Thursday is named" .)
