Overview
An alley or alleyway is a narrow lane, path, or passageway, often reserved for pedestrians, which usually runs between, behind, or within buildings in the older parts of towns and cities. It is also a rear access or service road (back lane), or a path, walk, or avenue (French allée) in a park or garden.
A covered alley or passageway, often with shops, may be called an arcade. The origin of the word alley is late Middle English, from "walking or passage", from "to go", from "to walk".
Definition
The word alley is used in two main ways:
It can refer to a narrow, usually paved, pedestrian path, often between the walls of buildings in towns and cities. This type is usually short and straight, and on steep ground can consist partially or entirely of steps.
It also describes a very narrow, urban street, or lane, usually paved, which may be used by slow-moving local traffic, though more pedestrian-friendly than a regular street. There are two versions of this kind of alley:
A rear access or service road (back lane), which can also sometimes act as part a secondary vehicular network. Many Americans and Canadians think of an alley in these terms first.
A narrow street running between houses or businesses. This type of alley is found in the older parts of many cities, including American cities like Philadelphia and Boston (see Elfreth's Alley, Philadelphia, Pennsylvania). Many are open to local traffic.
