Juliet's beloved (5)
I believe the answer is:
romeo
'juliet's beloved' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for romeo that I've seen before include "Peripheral figure" , "Casanova" , "Literary lover" , "''O ..., ..., wherefore are thou ....'' (Shakespeare)" , "Famous lover" .)
