Usage

What is an alley? An alley is a narrow passage between buildings or other structures. The word alleyway means the same thing. Alley can also refer to a narrow path or passage behind a row of houses, such as one that allows access to garages and back yards. An alley can also be a narrow street or lane—the word alley might even be used in the name of such a street, as in Elfreth’s Alley. All of these senses of alley refer to passages that are outside—you wouldn’t normally call a narrow passage an alley if it is indoors. The term bowling alley refers to a building with lanes for bowling—which can also be called alleys. The proper plural of alley is alleys. Example: We took a shortcut through the narrow alley between the shops.

Etymology

Origin of alley¹

First recorded in 1350–1400; Middle English al(e)y, from Middle French alee “walk, passage,” noun use of feminine of ale, past participle of aler “to walk,” probably from unattested Vulgar Latin allārī, from allātus, past participle of afferre “to bring”; see also amble

Origin of alley²

First recorded in 1710–20; probably al(abaster) + -y ², spelling to conform with alley ¹

Explanation

An alley is a narrow street with walls or buildings on both sides, like the dark alley everyone warns you not to walk down alone. Alley comes from the Old French word alee, meaning "a path, passage, way, corridor," which itself likely comes from the Latin word ambulare "to walk." That sums up what an alley is — a street that is usually too narrow for cars, though it is easy to walk there. However, alleys are often associated with danger and crime because they don't have much light shining in them, and it is easy for shady characters to hide.
