Cameron's mad love (7)
I believe the answer is:
romance
'love' is the definition.
(I know that romance is a type of love)
'cameron's mad' is the wordplay.
'mad' indicates anagramming the letters.
'cameron' anagrammed gives 'ROMANCE'.
(Other definitions for romance that I've seen before include "Court" , "Novel - affair" , "(Wonderful) piece of fiction" , "Group of languages" , "Cameron (anag) - love story" .)
