The Chinese word **扭伤** (niǔshāng) is a compound word formed through a logical semantic combination: the first character **扭** (niǔ) means "to twist" or "to wrench," describing the action, while the second character **伤** (shāng) means "injury" or "to hurt," indicating the result. Together, they create a cause-and-effect verb-noun compound that literally means "twist-injury," or more naturally, "to sprain" (as in a joint or muscle), precisely defining an injury caused by a twisting motion.
