Study with a cathedral administrative (4)
I believe the answer is:
dean
'cathedral administrative' is the definition.
I can't tell whether this defines the answer.
'study with a' is the wordplay.
'study' becomes 'den' (term for a study or office).
'with' means one lot of letters goes inside another.
'den' going around 'a' is 'DEAN'.
Can you help me to learn more?
(Other definitions for dean that I've seen before include "Senior church official" , "A senior clergyman - Swift was one" , "Churchman" , "University officer" , "College official" .)
