Nonsense from some backward well-off fugitives (4)
I believe the answer is:
guff
'nonsense' is the definition.
(I've seen this before)
'some backward well-off fugitives' is the wordplay.
'backward' is a reversal indicator.
'some' indicates a hidden word (some of the parts of the word are used).
'ffug' is hidden within 'well off fugitives'.
'ffug' in reverse letter order is 'GUFF'.
'from' acts as a link.
(Other definitions for guff that I've seen before include "Worthless ideas or talk" , "chat" , "Tripe" , "Worthless talk/ideas" , "Slangy nonsense, empty talk" .)
