The word "依附" is formed by combining the characters "依" and "附". "依" is composed of the radical "亻" (person) and "衣" (clothing), conveying the meaning of relying on or depending on. "附" consists of the radical "阝" (mound) and "付" (to hand over), indicating attaching or adhering to something. Together, these characters create a compound word where "依" contributes the sense of dependence and "附" adds the sense of attachment, resulting in the overall meaning of attaching oneself to or depending on someone or something.
