This book is the result of my research during my PhD in Portuguese Language at the State University of Rio de Janeiro, in which I investigated the operators that interact in the production of meaning in a discourse. These operators have been echoed by authors such as O. Ducrot, P. Charaudeau, M. Bakhtin and Bronckart, among others. In this way, these aspects, called discursive operators here, are fundamental agents for the description and apprehension of meaning. Although we see the text as a constitutive element of discourse, we reaffirm that discourse is the space that brings together the conditions for the production of meaning, because it is there that the interaction between the interlocutors takes place, with their idiosyncrasies and their historical-social traits; it is there that we can see the role of the context in which these interactions are generated, as well as the presumed ideas of the subjects in the communication situation. If the text encompasses the concrete trait, the discourse involves the enunciative space, in which voices dialogue and polemicise, producing, with the help of other operators, the meaning of the message conveyed.
