Passage between rows of seats (5)
I believe the answer is:
aisle
'passage between rows of seats' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for aisle that I've seen before include "Supermarket feature" , "Passageway between blocks of seats" , "Path between seats in church" , "Way between seat blocks" , "Walkway between seats" .)
