The Chinese word **磨损 (mósǔn)**, meaning "to wear down" or "attrition," is a typical **verb-result compound** formed through logical semantic combination. It is composed of two characters: **磨 (mó)**, which means "to grind" or "to polish" (indicating the abrasive action), and **损 (sǔn)**, which means "to damage" or "to lose" (indicating the resultant state). Together, they create a cause-and-effect relationship where the process of grinding (磨) directly leads to the outcome of damage or loss (损), perfectly encapsulating the concept of mechanical or gradual wear.
