Etymology: "Namespace" is a plain compound: "name" joined to "space," meaning a space in which names are kept and distinguished from one another. The idea behind it is that a name only has to be unique within its own container, so the same label can safely appear in two separate places without colliding. The word is built entirely from two common English elements, and its meaning follows directly from them. Its sense as a bounded area for sorting items comes from that literal picture: a region where a name holds good. Programmers and computer scientists use it most often for such regions, where identical names can coexist as long as they sit in different namespaces, but the same logic applies to any system that groups labels into separate, controlled domains.
