When you begin learning English it’s quite difficult to understand the difference between aisle and corridor. But in fact, you need to remember the only thing.
Aisle is an open passage in one big room.
Corridor is a an enclosed long passage inside a building between rooms.
So, there is an aisle between seats in the cinema or aisles between shelves in a supermarket. And there is a corridor in a building that connects halls and rooms. For example:
Glass corridor connects underground concrete extension to house in Spain.
One-way signs will be added to the floors of each aisle to direct shoppers and help everyone maintain social distance.
