Hurl a return to a reversion (9)
I believe the answer is:
throwback
'a reversion' is the definition.
(synonyms)
'hurl a return' is the wordplay.
'hurl' becomes 'throw' (I've seen this before).
'a return' becomes 'back' (I can't justify this - if you can you should give a lot more credence to this answer).
'throw'+'back'='THROWBACK'
'to' is the link.
Can you help me to learn more?
(Other definitions for throwback that I've seen before include "Reversion to an earlier type" , "Instance of reversion to ancestral type" , "Atavism" , "someone showing old-fashioned tendencies" , "Return" .)
