Third nun wrongly charged with a cowardly crime (3,3,3)
I believe the answer is:
hit and run
'third nun wrongly charged with a cowardly crime' is the definition.
I can't judge whether this defines the answer.
'third nun wrongly charged with a' is the wordplay.
'wrongly' indicates anagramming the letters.
'charged with' is an insertion indicator (inserted letters charge into others).
'third'+'nun'='thirdnun'
'thirdnun' with letters rearranged gives 'hitndrun'.
'hitndrun' going around 'a' is 'HIT-AND-RUN'.
Can you help me to learn more?
(Other definitions for hit and run that I've seen before include "sort of accident" , "Successes in theatre" , "associated with aggressive batsman?" , "Criminal activity" , "Type of road accident" .)
