Copy a cradle (4)
I believe the answer is:
crib
I believe this is a double definition.
'copy' is the first definition.
(thesaurus)
'a cradle' is the second definition.
(thesaurus)
(Other definitions for crib that I've seen before include "A baby's cot in America" , "Plagiarise - cattle stall" , "Cot; plagiarize" , "Nativity model" , "Nativity scene; copy illicitly" .)
