# Co-reference Co-reference signals the referential relationships between utterances. It is the way discourses \[a.k.a. [Performance](/performance.md)s i.e. series of events that follow each other] are formed: it creates the social history of discourse. [Metapragmatic grammar](/metapragmatic-grammar.md) 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](/discourse.md) (the poetic function of meter) and through co-reference. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
