overarching

This term describes a unifying element that binds various disparate parts into a single cohesive whole. It suggests a high-level perspective, often used in professional or academic settings to describe a primary goal, theme, or principle that governs everything beneath it. In a physical sense, it describes a literal curved structure that spans an area. While the figurative use is far more common in modern English, the physical sense maintains the image of a protective or enclosing canopy.
