ABSTRACT
The comment function is defined as an expression of the speaker oriented towards the content of what was said, adding an opinion or evaluation. It moves on the level of dictum and not on the level of modality or enunciation. It generally falls back on the content of the preceding speech. It implies a certain duplication of the speaker in monologic discourse, in two enunciators.
In the literature, we find works on comment clauses, structures that in many cases can become fixed as discursive operators, and are included among rhetorical relations.
The chapter analyzes the nature of the comment relation and its classification as a structural, argumentative or modal relation. It also studies the different macrosyntactic constructions that express it: discourse operators (que ya es decir), peripheral complements in the right margin, whether they are expressed by nominal or sentential structures (such as relative antecedent sentence structures). They can be introduced by deictics, which take up what was said in the preceding sentence, or by conjunctions such as y, o and que. To this, we can add evaluative statements expressed by adjectives. In all cases, extrapropositionality is a recurrent feature.
