Sports accessory all bent out of shape (7)
I believe the answer is:
netball
'sports accessory' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'all bent out of shape' is the wordplay.
'out of shape' indicates an anagram.
'all'+'bent'='allbent'
'allbent' is an anagram of 'NETBALL'.
Can you help me to learn more?
(Other definitions for netball that I've seen before include "Sport whose players wear bibs" , "Team game, played mainly by women" , "Team sport" , "Team game for tall Ben" , "Team game/sport" .)
