What term refers to the linguistic components of several sentences?

The term that refers to the linguistic components of several sentences is "discourse." Discourse encompasses not just individual sentences but also how they interact and connect to form cohesive and coherent communication. This includes the organization of language in spoken and written form, taking into account elements such as context, the relationships between speakers or writers, and the overall meaning conveyed through a sequence of sentences.

In contrast, dialogue typically refers to a conversation between two or more individuals, focusing more on the exchange of speech rather than the broader structure. Textuality addresses the qualities that define a text and its interpretation but does not specifically reference multiple sentences. An utterance is a single instance of speech or writing, which can be part of discourse but does not encompass the broader linguistic components found across multiple sentences.
