Prince redesigned court for district (8)
I believe the answer is:
precinct
'district' is the definition.
(precinct is a kind of district)
'prince redesigned court' is the wordplay.
'redesigned' indicates anagramming the letters.
'court' becomes 'ct'.
'prince' anagrammed gives 'precin'.
'precin'+'ct'='PRECINCT'
'for' acts as a link.
(Other definitions for precinct that I've seen before include "Pert C-in-C (anag.)" , "Enclosed area round, eg, a cathedral" , "District of a city or town marked out for a particular purpose" , "Area around a cathedral or church" , "District of authority" .)
