The word 捐款 is formed by combining two meaningful characters: 捐, which carries the core idea of "to contribute" or "to donate" (an act of giving something up), and 款, which specifies the object involved, meaning "a sum of money" or "funds". Their union is not merely a sum of parts but a conceptual fusion, where the action of donating is intrinsically linked to a monetary context, thus directly creating the composite meaning of "to donate money" or, as a noun, "a monetary donation". This formation follows a logical and semantic pattern common in Chinese, where a verb or action (捐) is paired with its direct object or target (款) to define a specific and complete concept.
