Novel railing violently against love (8)
I believe the answer is:
original
'novel' is the definition.
('original' can be similar in meaning to 'novel')
'railing violently against love' is the wordplay.
'violently' indicates anagramming the letters.
'against' says to put letters next to each other.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'railing' with letters rearranged gives 'riginal'.
'riginal' after 'o' is 'ORIGINAL'.
(Other definitions for original that I've seen before include "New in character or design - not a copy" , "- - sin" , "Not an imitation, the first" , "Novel - archetype" , "Not derived or copied form something else" .)
