Church walkway (5)
I believe the answer is:
aisle
'church walkway' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for aisle that I've seen before include "Passage between pews" , "Passageway between blocks of seats" , "Passage between rows of seats" , "Passage between seating blocks" , "Passage between shelves in supermarket" .)
