Cheat or swindle (7)
I believe the answer is:
defraud
I believe this clue is a double definition.
'cheat' is the first definition.
(I know this)
'swindle' is the second definition.
(I know that swindle can be written as defraud)
(Other definitions for defraud that I've seen before include "Bilk" , "Cheat, deceive" , "Illegally get money from (someone)" , "Swindle" , "Deprive of by deceit" .)
