The word 绑架 is formed by combining two characters, each contributing a vivid physical action to create the overall concept. The first character, 绑, depicts the act of tying or binding with ropes (suggested by the silk radical 纟). The second character, 架, evokes the image of propping up or carrying on a frame or support. When placed together, they sequentially illustrate the process of the crime: first restraining a person (绑), and then forcibly taking or controlling them (架), resulting in the meaning of "to kidnap".
