Fraudulent copy or imitation (7)
I believe the answer is:
forgery
I believe this clue is a double definition.
'fraudulent copy' is the first definition.
(I've seen this before)
'imitation' is the second definition.
(I know that forgery is a type of imitation)
(Other definitions for forgery that I've seen before include "Counterfeiting" , "Fraudulent copy" , "Fraudulent copy(ing)" , "Not the genuine article" , "making money illegally" .)
