Person deceived into making a copy? (4)
I believe the answer is:
dupe
'a copy?' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for dupe that I've seen before include "Pawn, mug" , "One who is cheated" , "Deceive, trick" , "Hoodwink, deceive" , "Delude" .)
