The Chinese word **残余** (cányú), meaning "remnants" or "residue," is a compound formed by combining two characters with closely related meanings. The first character, **残** (cán), carries the core ideas of "damage," "incomplete," or "remaining fragment." The second character, **余** (yú), means "surplus," "leftover," or "excess." When combined, they create a synergistic meaning where **残** emphasizes the damaged or degraded state of what remains, while **余** underscores that it is a leftover portion from a larger whole. Thus, the term vividly denotes what is left behind after a main part has been destroyed, removed, or has decayed, often used for physical debris, outdated social elements, or lingering influences.
