Discourse is not just a means of expressing thought; it is also an autonomous body, an act through which we aim to achieve a certain effect. Modern linguistics proposes a broader definition of discourse, as a discrete and unique enunciative process, where the speaker or author makes language concrete through speech (in the Saussurian sense), and describes the various acts (oral, illocutionary, perlocutionary) that discourse performs.

This book examines discourse, an object of analysis and criticism, from a wide range of perspectives. Among the concepts explored are the contributions of rhetoric in the art of discourse, the evolution of multiple approaches and the main methods of discourse analysis conducted by a variety of researchers. The book deepens our knowledge and understanding of discourse, a concept on which any research related to information and communication can be based.
