Co-reference

Co-reference signals the referential relationships between utterances. It is the way discourses [a.k.a. Performances i.e. series of events that follow each other] are formed: it creates the social history of discourse. Metapragmatic grammar is co-referential. It allows you to link one speech event to another. Co-reference builds upon the flow of indexical time through a past, present, and future. Each utterance signals its relationship to previous discourse through the rhythm of a Discourse (the poetic function of meter) and through co-reference.
