The word 透明 (tòumíng), meaning "transparent", is a logical compound formed by combining two meaningful characters: 透 (tòu), which carries the core idea of "penetrating through" or "passing through", and 明 (míng), meaning "bright" or "clear". Together, they create the conceptual image of light or sight passing through an object clearly and without obstruction, which perfectly defines transparency. This formation is typical of Chinese morphology, where two independent morphemes are joined to express a new, composite idea that is directly derived from the sum of their parts.
