Aped (6)
I believe the answer is:
copied
'aped' is the definition.
('copy' can be a synonym of 'ape')
This is all the clue.
(Other definitions for copied that I've seen before include "Imitated, reproduced" , "Reproduced (something)" , "Imitated or recreated" , "most sincerely flattered" , "made a transcript" .)
