A man in the romantic mould (4)
I believe the answer is:
hero
'a man' is the definition.
(I have seen 'Courageous man' mean 'hero' so perhaps 'man' could also mean 'hero')
'in the romantic mould' is the wordplay.
'in' says the answer is hidden in the clue.
'HERO' can be found hidden inside 'the romantic mould'.
(Other definitions for hero that I've seen before include "object of adulation" , "One much admired for courage" , "Brave guy" , "Revered figure" , "Male protagonist" .)
