Never smart, supporting police force (4,5,3)
I believe the answer is:
pigs might fly
'never' is the definition.
Both the answer and definition are adverbs.
Maybe they are linked in a way I don't understand?
'smart supporting police force' is the wordplay.
I cannot quite understand how this works, but
'smart' could be 'fly' (fly can informally mean smart or well-dressed) and 'fly' is found in the answer.
'force' could be 'might' (might can mean power or force) and 'might' is present in the answer.
The remaining letters 'pigs' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pigs might fly that I've seen before include "Ironic expression of disbelief or impossibility" , "No chance" , "highly unlikely" , "It will never happen!" , "I wish (but it won't happen!)" .)
