The word 聚集 is formed by combining two characters, 聚 and 集, which both independently carry the core meaning of "to gather" or "to assemble". This is a common method in Chinese word formation where two synonyms or near-synonyms are paired together to create a single, reinforced concept. The character 聚 contributes the image of people coming together, while 集 adds the notion of things being collected into one place. Their combination does not create a new, abstract meaning but rather intensifies and solidifies the shared idea of a concentrated coming together, resulting in a cohesive term for "to gather, to assemble, or to congregate".
