Imitates; copies (6)
I believe the answer is:
mimics
This clue is a double definition.
'imitates' is the first definition.
(mimicking is a kind of imitating)
'copies' is the second definition.
(mimicking is a kind of copying)
(Other definitions for mimics that I've seen before include "Imitates for satirical effect" , "Impersonates or parrots" , "Copies - apes" , "Imitates satirically" , "Imitators" .)
