‘队伍’ (duì wu) literally combines ‘队’ (a unit or squad, often military or organized) and ‘伍’ (an ancient term for a small group of five soldiers). Together, they form a general noun meaning ‘team’, ‘group’, or ‘formation’ — emphasizing order, shared purpose, and collective identity. It’s commonly used for organized groups such as sports teams, volunteer squads, school activity groups, or people lined up in sequence.

Unlike the more casual ‘组’ (zǔ) or ‘班’ (bān), ‘队伍’ carries a subtle connotation of discipline, cohesion, and visible structure — think of people standing in line, marching together, or working toward a common goal. It appears frequently in educational, community, and public settings, especially when coordination or unity is highlighted. While it can refer to animal groups (e.g., a flock of birds moving as one), its primary use is human-centered and socially organized.
