“The merit of this new book by Ruth Amossy is to provide a faithful description of discursive practices that have been neglected for too long and thus to allow a better understanding of the meaning and function of verbal behaviours that deviate from rational and reasonable negotiation between interlocutors … . This book, which is a major contribution to the theory of argumentation, is also a powerful stimulus for students, offering them an extremely rich range of examples and analyses.” (Jean-Claude Guerrini, Argumentation, Vol. 36 (3), 2022)
