Aggrieved by the return of the Greek archer (4)
I believe the answer is:
sore
'aggrieved' is the definition.
(I've seen this before)
'the return of the greek archer' is the wordplay.
'the return of' shows that the letters should be reversed in order.
'the greek archer' becomes 'eros' (I've seen this in another clue).
'eros' backwards is 'SORE'.
'by' acts as a link.
(Other definitions for sore that I've seen before include "To be very old" , "Bruised" , "Painful or tender" , "Hard" , "Hurting, painful" .)
