The word 团聚 is formed by combining two characters that each contribute a layer of meaning about coming together. 团 (tuán) conveys the idea of something round, a circle, or a united group, evoking imagery of completeness and unity. 聚 (jù) specifically means to gather, assemble, or congregate. When paired, they create a compound where the first character, 团, describes the nature of the gathering, a unified, often intimate circle, and the second, 聚, provides the core action of assembling. Together, they visually and conceptually merge to form the specific idea of a reunion, particularly a warm, familial gathering where separated members reconvene into a whole.
