The word 团伙 is formed by combining two characters, 团 and 伙, each contributing a core idea about a group of people. 团 suggests an organized, unified body or circle, while 伙 conveys a more informal band or partnership, often for a shared purpose. Their combination merges these concepts, creating a single term that intrinsically implies a cohesive yet often collusive or clandestine collective, with the meaning emerging from the conceptual synergy of the two parts rather than a grammatical rule.
