The word **玻璃杯** (*bōli bēi*, meaning "drinking glass") is a straightforward compound noun formed by combining two meaningful elements: **玻璃** (*bōli*), which is the word for "glass" as a material, and **杯** (*bēi*), which means "cup" or "vessel for drinking." It follows a common structural pattern in Chinese where a modifier (the material, **玻璃**) is placed before a core noun (the object type, **杯**), creating a clear and logical meaning of "a cup made of glass." This formation is semantically transparent, directly describing the object by its composition and function.
