Plagiarised (6)
I believe the answer is:
copied
'plagiarised' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for copied that I've seen before include "Reproduced (something)" , "made a transcript" , "Imitated or replicated" , "Imitated or recreated" , "Imitated, reproduced" .)
