Not only are aisle and isle homophones (words having the same pronunciation but different meanings, origins, or spelling), they are also spelled similarly. The only difference is the beginning letter a in aisle. This causes greater confusion among English writers, causing them to interchange the two terms in their sentences. This post will allow you to distinguish between the two in terms of their definitions and uses.
The word aisle is used as a noun referring to “a passage between rows of seats in a building such as a church or theater, an airplane, or a train” or “a passage between shelves of goods in a supermarket or other buildings.”
