Bridal path (5)
I believe the answer is:
aisle
'bridal path' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aisle that I've seen before include "Passage between blocks of chairs" , "channel" , "Passages between seating areas" , "Passageway in theatre" , "way for prospective union members?" .)
