Romeo and Juliet, say, misleading solver (6)
I believe the answer is:
lovers
'romeo and juliet' is the definition.
(I've seen this in another clue)
'misleading solver' is the wordplay.
'misleading' indicates anagramming the letters (I've seen this in other clues).
'solver' anagrammed gives 'LOVERS'.
'say' acts as a link.
(Other definitions for lovers that I've seen before include "Romeo and Juliet, perhaps" , "Fans" , "Romantic pair" .)
