The Chinese word **帮会 (bānghuì)** is a compound noun formed through the morphological process of **coordination**, where two synonymous or semantically related characters are combined to create a more specific meaning. The first character, **帮 (bāng)**, originally means "to help" but here carries the sense of a "faction," "gang," or "organized group." The second character, **会 (huì)**, means "society," "association," or "gathering." When combined, **帮会** semantically merges these concepts to specifically denote a **secret society, sworn brotherhood, or underground organization**, often with historical connotations to groups like triads or guilds that operated with their own strict codes and structures outside of official authority.
