The word 传播 is formed through the conceptual blending of two ancient, vivid actions: 传 (chuán), meaning to pass or hand something along in a continuous line, like a relay, and 播 (bō), meaning to sow seeds by casting them broadly across a field. The compound visually and notionally merges these two motions, the sequential passing from one point to the next and the simultaneous wide scattering outward, to create a single, fluid concept of dissemination, where something (like information or culture) is both transferred through a chain and diffused expansively into an environment.
