Affection right for Romeo (5)
I believe the answer is:
lover
'romeo' is the definition.
(I've seen this before)
'affection right' is the wordplay.
'affection' becomes 'love' (I've seen this before**).
'right' becomes 'r' (common abbreviation).
'love'+'r'='LOVER'
'for' is the link.
(Other definitions for lover that I've seen before include "Opposite of hateful type" , "Juliet, for example" , "'Lady Chatterley's - - ' by D H Lawrence" , "Lothario" , "Beau" .)
