Division in the church? (5)
I believe the answer is:
aisle
'division in the church?' is the definition.
(walkway through a church)
This is the entire clue.
(Other definitions for aisle that I've seen before include "Here comes the bride" , "Passage between blocks of chairs" , "Way between seating areas" , "Passage down the side of a church nave" , "Passage between seating blocks" .)
