See replays regularly (3)
I believe the answer is:
ely
'see' is the definition.
(see is a place with a cathedral - e.g. Ely)
'replays regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternate letters of 'replays' are 'ELY'.
(Other definitions for ely that I've seen before include "Cambs diocese" , "Cambs cathedral" , "Fenland cathedral town" , "UK city" , "Cambs. city" .)
