The Chinese word 葡萄干 (pútáogān), meaning "raisin," is formed through a straightforward compound word structure common in the language. It combines the noun 葡萄 (pútáo), which means "grape," with the noun 干 (gān), which in this context means "dried thing" or "dried fruit." The word thus follows a modifier-head construction where 葡萄 ("grape") specifies the type, and 干 ("dried") functions as the core noun, literally creating the meaning "grape-dried-thing" or "dried grape." This logical, semantic combination directly describes the object's nature and origin.
