What does overarch mean?
Overarch is a formal verb meaning to extend over something or, more commonly in modern usage, to provide a broad structure, principle, or plan that encompasses many smaller activities. An overarching strategy might coordinate a government's education, health, and economic policies, while an overarching principle could guide the decisions of an organization. The word suggests something broad and unifying rather than narrowly limited to one area. It can also be used literally for a physical structure that arches over a space. Because “overarch” combines the sense of being above or across something with the idea of an arch or covering, it carries a subtle suggestion of sheltering, organizing, or holding elements together. Its abstract uses are especially valuable in describing the central framework that gives direction to otherwise separate parts.
