Resumen:
In discourse analysis, the utterance is the unit of analysis and not the sentence. For discourse analysis, what matters is to identify the relationship between the speaking subject and the object of enunciation, in terms of meaning, which can only be a social-historical product. Hence, such an analysis is based on a theory of enunciation, and not on linguistics, since it is a matter of observing the socio- discursive dimension of utterances and not the formalism of the sentence. In this sense, we will try to review (inspired by the theoretical contributions of Michel Foucault, from The Archaeology of knowledge) how the notion of statement has its foundations in the process of enunciation. With this, we try to specify the notion of "discursive structure" as a unit of analysis in its methodological possibilities.
