Source of long time on rebound after misfortune of a criminal nature (7)
I believe the answer is:
illegal
'source of long time on rebound after misfortune of a criminal nature' is the definition.
I can't tell whether this definition defines the answer.
'source of long time on rebound after misfortune' is the wordplay.
'source of' suggests taking the first letters (the start - or source - of the word).
'time' becomes 'age' (an age is a period of time).
'on rebound' says the letters should be written backwards.
'after' says to put letters next to each other.
'misfortune' becomes 'ill' (ill is a kind of misfortune).
The initial letter of 'long' is 'l'.
'l'+'age'='lage'
'lage' backwards is 'egal'.
'egal' put after 'ill' is 'ILLEGAL'.
Can you help me to learn more?
(Other definitions for illegal that I've seen before include "Against the rules" , "Criminal, illicit" , "Not allowed" , "Prohibited by law" , "Forbidden" .)
