The Chinese word 摇晃 (yáo huàng), meaning "to shake" or "to rock," is a typical example of a **synonymous compound** formed through the combination of two characters with closely related meanings. The first character, 摇 (yáo), primarily means "to shake" or "to wave," while the second, 晃 (huàng), conveys "to sway" or "to wobble." By pairing these two verbs, the word creates a reinforced and more vivid sense of unsteady, back-and-forth motion, where the individual components synergistically enhance and specify the overall meaning, a common morphological process in Chinese for forming disyllabic verbs.
