The word 出动 is formed by combining two characters: 出 (chū), which carries the core meaning of "to go out" or "to emerge", and 动 (dòng), which means "to move" or "to act". Their conceptual fusion creates a new, composite idea where the sense of "emerging" merges with the sense of "acting", resulting in the meaning of initiating a coordinated movement or action, typically of a group or force, from a starting point into activity.
