The compound word 动摇 is formed through the combination of two semantic components: the character 动 (dòng), meaning "to move" or "to act", and 摇 (yáo), meaning "to shake", "to rock", or "to sway". Together, they create a metaphorical and reinforced meaning that extends beyond simple physical motion. The word describes a state or action of being unsteady, unstable, or wavering, most commonly applied to abstract concepts like resolve, faith, foundations, or positions, implying they are being shaken and are therefore no longer firm or steadfast. This formation is a typical example of a coordinative compound, where two characters with similar meanings combine to express a single, nuanced concept that emphasizes instability and change.
