Cupid's love
I believe the answer is:
psyche
'cupid's love' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for psyche that I've seen before include "Subject of 11 [ODE]" , "Analyse" , "Soul - girl from Greek mythology" , "Core of one's personality" , "The soul, spirit or mind" .)
