The Chinese word 球赛 (qiúsài), meaning "ball game" or "sports match", is a compound noun formed through the logical combination of two meaningful characters: 球 (qiú), which means "ball", and 赛 (sài), which means "competition" or "match". It follows a common modifier-head structure in Chinese morphology, where the first element 球 specifies the type (a ball-related activity), and the second element 赛 functions as the core head noun indicating the event category. This formation is analogous to English compounds like "basketball game", creating a precise and efficient term for a sporting contest involving a ball.
