Copy from paper (3)
I believe the answer is:
ape
'copy' is the definition.
(ape can mean to copy or imitate)
'from paper' is the wordplay.
'from' indicates the answer is hidden within the clue.
'APE' can be found hidden inside 'paper'.
(Other definitions for ape that I've seen before include "Parrot" , "Simulate" , "Take off" , "Anthropoid primate" , "drill" .)
