Part of spoof actually for real (7)
I believe the answer is:
factual
'real' is the definition.
('factual' can be a synonym of 'real')
'part of spoof actually for' is the wordplay.
'part of' indicates a hidden word.
'FACTUAL' is hidden within 'spoof actually for'.
(Other definitions for factual that I've seen before include "like a TV documentary?" , "True-to-life" , "Related to the truth" , "Relating to reality" , "True to life" .)
