Strong cold wind around island impaired hearing (8)
I believe the answer is:
mistrial
'strong cold wind' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'around island impaired hearing' is the wordplay.
'around' means one lot of letters goes inside another.
'island' becomes 'i' (geographical abbreviation).
'impaired' becomes 'ms' (I am not sure about this - if you are sure you should believe this answer much more).
'hearing' becomes 'trial' (as in a court case).
'i' inserted inside 'ms' is 'mis'.
'mis'+'trial'='MISTRIAL'
Can you help me to learn more?
(Other definitions for mistrial that I've seen before include "Invalid court procedure" , "Court hearing invalidated by error" , "When it's declared, the case must be heard again" , "Inconclusive or invalid court proceedings" , "Court procedure made void by error" .)
