Within novel, it is mainly an aristocratic attitude? (7)
I believe the answer is:
elitism
'attitude?' is the definition.
(elitism is a kind of attitude)
'within novel it is mainly an aristocratic' is the wordplay.
'within' indicates a hidden word.
'ELITISM' is hidden within 'novel it is mainly aristocratic'.
(Other definitions for elitism that I've seen before include "Belief in the best" , "Superior attitude of those in power" , "Belief in government by a chosen few" , "Preferring the best" , "Government by select group" .)
