radiate
This term evokes the image of a central source projecting outward in all directions. In a physical sense, it describes the emission of energy like heat or light, often implying a steady, pervasive flow rather than a single burst. When applied to human emotion, it suggests a quality so intense that it becomes visible to others, as if the person is a light source. This usage is almost always positive, describing states like joy, confidence, or warmth. In urban planning or geometry, it describes a hub-and-spoke arrangement where paths diverge from a single origin.
