The word 聚会 is formed conceptually by combining two characters that each contribute a layer of meaning about coming together. The first character, 聚, carries the core idea of "to assemble" or "to gather", picturing people or things converging into one place. The second character, 会, adds the specific notion of "a meeting" or "a gathering", implying a social or purposeful event. Fused together, they create a single concept where the action of assembling (聚) is for the explicit purpose of a collective meeting (会), perfectly encapsulating the idea of a social gathering or party.
