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' says the answer is hidden in the clue.
'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" .)
