Parrot or gorilla? (3)
I believe the answer is:
ape
I believe this is a double definition.
'parrot' is the first definition.
(both can mean to imitate)
'gorilla?' is the second definition.
(gorilla is a kind of ape)
'or' is the link.
(Other definitions for ape that I've seen before include "Imitate uncritically" , "drill" , "Anthropoid primate" , "Wild animal" , "gorilla" .)
