Path to the altar (5)
I believe the answer is:
aisle
'path to the altar' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aisle that I've seen before include "Passages between seating areas" , "Passageway in theatre" , "Here comes the bride" , "Passage between seating areas" , "Passage between blocks of chairs" .)
