Love hurting after rejection (4)
I believe the answer is:
eros
'love' is the definition.
(Greek god of love)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eros that I've seen before include "Famous statue in Piccadilly, London" , "asteroid four hundred and thirty three" , "Sore about love god" , "Winged archer" , "very centre of London?" .)
