Wail in mimicry (3)
I believe the answer is:
cry
'wail' is the definition.
(to wail is to cry out)
'mimicry' is the wordplay.
'CRY' is hidden within the letters.
However, I am unsure how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cry that I've seen before include "Sound of pain or grief" , "Blubber" , "Shout - weep" , "Don't . . . over spilt milk" , "Shed tears" .)
