Lover of Juliet (5)
I believe the answer is:
romeo
'lover of juliet' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for romeo that I've seen before include "A great lover" , "Shakespearean character" , "Lover boy" , "Lover; R (radio comms.)" , "Ladies' man" .)
