Lover boy wounded making comeback (4)
I believe the answer is:
eros
'lover boy' is the definition.
(Greek love god)
'wounded making comeback' is the wordplay.
'wounded' becomes 'sore' (I've seen this in another clue).
'making comeback' says the letters should be written backwards.
'sore' in reverse letter order is 'EROS'.
(Other definitions for eros that I've seen before include "divinity" , "Statue of love-god in Piccadilly Circus in London" , "Goddess" , "Greek love-god" , "Arrow-shooting god" .)
