The word 纸杯 (zhǐbēi), meaning "paper cup", is a standard Chinese compound noun formed through a modifier-head structure, where the first character 纸 (zhǐ), meaning "paper", acts as the descriptive modifier that specifies the material, and the second character 杯 (bēi), meaning "cup", serves as the core noun or head, indicating the object's category; thus, the compound literally and logically translates to "paper cup".
