Does archery give him a sore back? (4)
I believe the answer is:
eros
'does archery give him a' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'sore back?' is the wordplay.
'back?' shows that the letters should be reversed in order (I've seen 'back' mean this).
'sore' backwards is 'EROS'.
Can you help me to learn more?
(Other definitions for eros that I've seen before include "Arrow-shooting god" , "divinity" , "Deity" , "Greek god of love - see statue in Piccadilly" , "Pagan god" .)
