The Chinese word 合成 (héchéng) is a compound word formed through the common morphological process of combination, where two independent, meaningful characters (morphemes) are joined to create a new, specific meaning. The first character, 合 (hé), carries the core meaning of "to combine", "to join", or "to unite", while the second character, 成 (chéng), means "to become", "to form", or "to accomplish". When combined, they create a verb meaning "to synthesize", "to compose", or "to put together to form a whole", where the action of combining (合) leads to the result of something being formed or accomplished (成). This structure exemplifies the typical and logical way in which modern Chinese vocabulary expands by combining existing semantic units.
