Cupid's lover (6)
I believe the answer is:
psyche
'cupid's lover' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for psyche that I've seen before include "Wife of Cupid" , "Subject of 11 [ODE]" , "The soul, spirit or mind" , "The beloved of Eros" , "inner spirit" .)
