The Chinese word **别针 (biézhēn)**, meaning "safety pin" or "brooch," is a compound noun formed through semantic combination. It consists of the character **别 (bié)**, which in this context carries the meaning "to pin" or "to fasten," and the character **针 (zhēn)**, which means "needle." The word thus literally translates to "pinning needle," a descriptive term that effectively conveys the object's primary function: a needle-like device used for fastening or attaching items together, which is a common and logical method of word formation in Chinese where two meaningful characters combine to create a new, precise concept.
