More than a capital district (6)
I believe the answer is:
parish
'district' is the definition.
(I know that parish is a type of jurisdiction)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for parish that I've seen before include "Kind of 2 down - has rip (anag)" , "Ecclesiastical district" , "Diocesan subdivision" , "Local government area" , "District with own church and clergyman" .)
