The Chinese word **交际** (jiāojì), meaning "social interaction" or "communication," is a compound term formed through semantic combination. Its first character, **交** (jiāo), carries the core meaning of "to hand over," "to intersect," or "to associate with," establishing the idea of mutual exchange and connection. The second character, **际** (jì), originally signifies a "border," "edge," or "between," and by extension conveys the notion of "inter-" or "relationship." When combined, these characters synthesize to create a nuanced concept that specifically denotes the active process of engaging with others within social boundaries, effectively encompassing communication, networking, and interpersonal exchange as a unified idea.
