Fly one out for a robbery (6)
I believe the answer is:
felony
'a robbery' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'fly one out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'fly'+'one'='flyone'
'flyone' with letters rearranged gives 'FELONY'.
'for' is the link.
Can you help me to learn more?
(Other definitions for felony that I've seen before include "Serious crime" , "Criminal offence" , "Grave crime" , "Criminal act" .)
