Greek Cupid (4)
I believe the answer is:
eros
'greek cupid' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eros that I've seen before include "Roman god of love, Cupid" , "Greek god of love - see statue in Piccadilly" , "Greek equivalent to Roman Cupid" , "asteroid four hundred and thirty three" , "Goddess" .)
