The use of dialogue creates a dramatic effect. Dialogue is an important tool for creating a sense of drama in literature, as it allows characters to interact with one another in a way that can reveal their thoughts, feelings, and motivations. By using dialogue, writers can create tension, conflict, and suspense, as well as reveal important information about the characters and the plot. Additionally, dialogue can help to bring a story to life by giving readers a sense of the characters' personalities and relationships. While dialogue can certainly be used for humorous, poetic, or ironic effect, its most fundamental purpose is to create drama by bringing characters into conflict with one another.
