The book by Victoria Guillén-Nieto focuses on hate speech seen through the lens of the combination of various legal and linguistic perspectives which result in several methodologies being called upon to support the analysis of the hate speech phenomenon. The author's starting point is the fact that so far very few significant studies on hate speech in the field of linguistics have been accessible. The general point of view adopted by Guillén-Nieto is that of legal practitioners and linguists who face major difficulties in dealing with language of hatred, particularly with the emergence and rapid evolution of new technologies and social networks. The author develops a linguistic perspective based on data, tools and solutions that linguists may provide to enable legal action to be taken.The macro-structure of the book consists of a preface and eight chapters. In the Preface the reader will find a detailed review of the bibliography on hate speech accompanied by some general considerations on the current status of research on hate speech in various areas of study. Then, the book is divided into two parts: Legal linguistics (Part I -Chapters 1-4) and Forensic linguistics (Part II -Chapters 5-8). Legal linguistics analyses the doctrinal content of the law and its linguistically-based structure, while forensic linguistics is concerned with helping to establish the facts on which a legal decision is based.In Chapter 1. Approaches to the meaning of hate speech, Guillén-Nieto considers various definitions of hate speech and adopts Wittgenstein's concept of family resemblance (2009 [1953]) with the aim of revealing to what extent it can be of use for the researchers in the area of linguistics and law who approach the phenomenon of hate speech. This perspective enables and supports the understanding that hate speech does not have a single meaning but rather several connotations that share certain affinities with each other. Thus it is not possible to identify features that would be shared by all scientific disciplines that deal with hate speech. The aforementioned thesis is proven by the author through Brown's ordinary language analysis (2017).In the following part of the chapter Guillén-Nieto gives an outline of legal scholarly attempts to define the concept of hate speech and she suggests its division into three categories, namely content-based hate speech, intent-based hate speech and harms-based hate speech. This section provides a diachronic overview of research on hate speech and shows very clearly that it might not be possible to create a single unified definition which could be used both in linguistics and legal studies.The author's main aim of this part of Chapter 1 is to show how heterogeneous hate speech is, regardless of the discipline that is chosen as the theoretical framework. The author cites a considerable number of studies that prove her thesis, but it shall be acknowledged that this has been a well-known assumption and a starting point for many studies on hate speech, especially in linguistics.
