The word "aisle" refers to a passageway or corridor between rows of seats, shelves, or other structures. It is commonly found in places like theaters, airplanes, grocery stores, and churches, providing access to different sections or areas. For example, when you're at a supermarket, the aisles are the areas where you find different products arranged on shelves.
The term "aisle" comes from the Old French word "ail," which means "wing" or "side." This, in turn, is derived from the Latin word "ala," meaning "wing." The connection to "wing" reflects the design of church architecture, where aisles are often located beside the main body of the church, resembling wings.
