The Chinese word **运动衫** (yùndòngshān), meaning "sports shirt" or "jersey," is a compound noun formed through modification, where the first element **运动** ("sport" or "exercise") acts as an attributive to specify and describe the second element **衫** ("shirt" or "upper garment"). This structure follows a common Chinese word-formation pattern of combining two independent, meaningful characters (morphemes) to create a new, specific term, with the modifier preceding the head noun to indicate the type or purpose of the shirt—essentially, a "shirt for sports."
