The word "赞助" is formed through the combination of two meaningful characters: "赞", which conveys notions of approval, support, and praise, and "助", which means to aid or assist. Together, they merge conceptually to create a compound idea where supportive approval is actively expressed through material or financial assistance, resulting in the integrated meaning of "to sponsor" or "patronage". This formation is a direct semantic synthesis, where both components contribute equally to the unified, action-oriented concept.
