Etymology: Whitehall began as a plain place name rather than a government term. Its Middle English elements are "whit" meaning "white" and "halgh," a word for a corner or nook, which later blended with "hall." The name referred to a particular stretch of London, and the great palace that once stood there was the seat of English kings. When the monarch's residence moved elsewhere, the government offices clustered around the site kept the name, so over time the street itself came to stand for the administration housed there. The shift from a location to an institution is what makes the word useful. People speaking of "Whitehall" in Britain mean the civil service and its policy-making, not any building or road. A single street name thus became shorthand for an entire system of government administration, much as other place names have come to stand for institutions elsewhere.
