Kieran File, How language shapes relationships in professional sports teams: Power and solidarity dynamics in a New Zealand rugby team. London: Bloomsbury, 2023. Pp. 239. Hb. £67.

This timely study—appearing at a moment when scandals over bullying and identity-based prejudice in elite sport are mushrooming—is grounded in the taken-for-granted, everyday interactional practices of a professional New Zealand rugby team. Kieran File’s empirically informed discourse analysis aims to establish a set of hypotheses or principles on which linguists can build a body of research about the culture of high-performance sport. The description of the conceptual structure of the investigation in chapters 1 and 2 is easily accessible to a broader audience, for whom discussions of power and ideology can be opaque. Sports practitioners, for instance, begin the book with a useful model of how the macro (in this case, interpersonal ideologies rooted in cultural knowledge) interacts with the micro (interactional dynamics, giving to relational ones) in practices they will find familiar. A core conceptual lens offered is the existence of three key roles—that of coach, captain, and players—which are treated with appropriate nuance in the content chapters, yet are easily transferrable to future studies of team dynamics. In chapters 3–6, File reveals the processes by which predictable asymmetrical power relations are maintained: how, for instance, coaches dominate interactional spaces to perform their agendas via mechanisms of control. While File does not make judgments, the reader is pointed to wider debates about the utility and ethics of power hierarchies in team sport. Some practices are obvious and overt, such as the initiating and closing of team talks, and these are co-constructed via the players’ silence or body language. Other finer-grained practices, such as the various methods of questioning used to exert ‘expert power’, elicit active participation from the players in order to perform different functions, from holding players accountable to motivating them at half-time. Power-sharing between the coaches and captain is an unequal and complex process sanctioned by the head coach, who, in essence, retains overarching authority. In the culture of high-performance sport, perhaps rugby in particular, the evidence suggests that shared power is an unpopular concept. Nevertheless, player-player relations were relatively more open and interactional, albeit within a separate informal and subtle hierarchy of rugbyplaying experience. Chapters 7 and 8 turn to solidarity. Among players, File found that a language of solidarity—for example, chants or terms of address—was used in attempts to bridge
