Copy primate (3)
I believe the answer is:
ape
I believe this clue is a double definition.
'copy' is the first definition.
(ape can mean to copy or imitate)
'primate' is the second definition.
(large primate)
(Other definitions for ape that I've seen before include "Wild animal" , "Parrot" , "Imitate, clumsy person (colloq.)" , "Send up" , "gorilla" .)
