Lover, beloved (10)
I believe the answer is:
sweetheart
I believe this clue is a double definition.
'lover' is the first definition.
(I know that sweetheart is a type of lover)
'beloved' is the second definition.
(I've seen this before)
(Other definitions for sweetheart that I've seen before include "boyfriend?" , "Love" , "Beloved" , "One loved" , "Lover" .)
