Convert copies tape in bishop's office (10)
I believe the answer is:
episcopate
'bishop's office' is the definition.
(I've seen this before)
'convert copies tape' is the wordplay.
'convert' indicates an anagram (I've seen this in other clues).
'copies'+'tape'='copiestape'
'copiestape' is an anagram of 'EPISCOPATE'.
'in' is the link.
(Other definitions for episcopate that I've seen before include "See" , "bishop's office" , "Bishopric" , "clergyman's office" .)
