The Chinese word **粉末** is a compound noun formed by combining two characters with closely related meanings to create a specific, reinforced concept. The first character, **粉 (fěn)**, primarily means "powder" or "dust," while the second, **末 (mò)**, means "end," "tip," or more figuratively, "the smallest particles" or "fine powder." Together, they form a **synonym compound**, where both components contribute a similar semantic idea of finely divided, granular material. This combination effectively narrows and emphasizes the meaning to refer specifically to a substance in a very fine, loose, particulate form, such as flour, cosmetic powder, or gunpowder.
