Copy special procedure (9)
I believe the answer is:
reproduce
'copy' is the definition.
(thesaurus)
'special procedure' is the wordplay.
'special' indicates anagramming the letters.
'procedure' anagrammed gives 'REPRODUCE'.
(Other definitions for reproduce that I've seen before include "Duplicate" , "Procreate or make a copy" , "[DOUBLE]" , "Procedure (anag.)" , "achieve propagation" .)
