According to the traditional grammars, what characterizes the demonstrative pronouns is its deictic function: they indicate the position of beings and notions in space or time in relation to the three persons of the speech (1st and 2nd person: this and 3rd person, that). Besides the deictic function, the grammars also mention anaphoric and cataforic function that, respectively, refer to something already mentioned and to what will be said in the speech. These ratings, however, do not account for other ways of these pronouns in oral and written discourse. Considering, therefore, the multifunctionality of the demonstrative pronouns, this research aims to describe and analyze their varied uses and semantic-pragmatic values. Thus, the theoretical assumptions underlying this research are those of Functional Discourse Grammar, a model proposed by Hengeveld (2004), which considers the language in use, the participants, the communicative purpose and the discursive content. The presented data underlines that the use of statements manifests extreme richness in the language, indicating a tendency to rewrite the basic functions of these pronouns. The evidences point to a semantic-pragmatic process of subjectivity in the use of demonstrative pronouns.
