Here's a fast and easy explanation: The exchange of spoken words between two or more characters in a book, play, or other written work is known as dialogue. Dialogic writing is all dialogue (between people) that is not narrative exposition. Narrative exposition is the telling of events in order to inform the reader about what happens next in the story. In other words, it's what you do when you write an essay or any other piece of non-fiction. Narrative exposition isn't difficult to do; it's just not necessary for good storytelling. Every story needs some form of exposition to give the reader information about what's going on, who's who, and so on, but dialogue often does this job better because the writer doesn't have to explain things explicitly. The reader can infer them by listening to the characters talk. Simple dialogue consists of two parts: speakers and content. There are four types of speakers in simple dialogue: one person, both people, either person, and unspecified persons. Simple dialogue can also be classified into five types according to the amount of content exchanged by the speakers: complete, incomplete, interrupted, unresolved, and repeated. Complete simple dialogue involves two or more speakers discussing one topic completely before moving on to another one.
