The word 主动 is formed by combining the character 主 (zhǔ), which carries the core meaning of "master", "primary", or "to host", with the character 动 (dòng), meaning "to move" or "action". Conceptually, it fuses the idea of being the "master" or initiating source with the concept of "movement", creating a compound that visually and semantically depicts action originating from one's own volition. Thus, it embodies the notion of "master-driven movement" or "self-initiated action", directly conveying its meaning of "proactive" or "taking the initiative" through this intrinsic pictorial and ideological marriage.
