Swindling (8)
I believe the answer is:
cheating
'swindling' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cheating that I've seen before include "Two-timing" , "Cleverly avoiding" , "It's quite unfair" , "Acting dishonestly to gain advantage" , "Swindling or defrauding" .)
