The word 餐桌 is formed by directly combining two meaningful characters: 餐 (cān), which means "meal" or "to dine", and 桌 (zhuō), which means "table". It is a conceptual fusion where the first character specifies the primary purpose or function, and the second character names the object itself. Together, they create a new, single concept, "dining table", by logically merging the idea of a meal with the object used for it.
