PURVIEW — [Noun] The defined scope, range, or limit of authority, concern, or legal applicability. From Middle English purveu ("proviso"), from Anglo-French purveu est ("it is provided"), the past participle of purveier ("to provide"), from Latin prōvidēre ("to foresee, provide"). Unlike "preview" (which offers an advance glimpse) or "provision" (which is the act of supplying), "purview" is a sanctioned domain, an intellectual or bureaucratic jurisdiction granted by decree. It is the precise column of figures an accountant is hired to audit, the narrow remit of a departmental inquiry, or the exact line on an organizational chart where your responsibility becomes another's—a cartography not of geography, but of permission, defining what is, and more importantly, what is not, your problem.
