God of both orders (4)
I believe the answer is:
thor
'god' is the definition.
(Norse god of thunder)
'of both orders' is the wordplay.
'of' indicates a hidden word.
'THOR' can be found hidden inside 'both orders'.
(Other definitions for thor that I've seen before include "Imitative artistic work" , "Wielder of hammer" , "can be classed as immortal" , "Norse god for whom Thursday is named" , "Divine figure" .)
