Peer's son gives wrong answers (8)
I believe the answer is:
response
'wrong answers' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'peer's son gives' is the wordplay.
'gives' indicates an anagram.
'peers'+'son'='peersson'
'peersson' with letters rearranged gives 'RESPONSE'.
Can you help me to learn more?
(Other definitions for response that I've seen before include "Preens so by way of answer" , "See porn (anag) -- answer" , "Reaction, reply" , "'Answer, reply (8)'" , "Answer - retort" .)
