The word 球队 is formed by combining two meaningful characters: 球 (qiú), meaning "ball", and 队 (duì), meaning "team" or "squad". It is constructed through a straightforward conceptual relationship where the first element, 球, specifies the domain or object of activity, in this case, sports or games played with a ball. The second element, 队, then identifies the social or organizational unit engaged in that activity. Together, they create a single, compound concept meaning "ball team", efficiently conveying the idea of an organized group formed for the purpose of playing a ball sport.
