The word 信任 is formed through a meaningful conceptual combination of its two component characters. The first character, 信, carries the core idea of "trustworthiness" or "belief", often associated with keeping one's word. The second character, 任, means "to assign" or "to bear a duty", implying responsibility and reliance. Together, they create a dynamic, two-way concept: 信 provides the foundational credibility and sincerity, while 任 extends this into the act of entrusting and depending upon someone, thus forming the complete idea of "trust" as both a feeling of belief and an action of placing faith in another.
