Answer:
Transitions play a major role in writing, they help to provide the flow of information when writing a formal, academic essay. For example, read a excerpt from this essay:
"In essence, the theme of transformation runs throughout Kafka’s novella, Langelaan’s short story, and the biographical pieces that detail the life of Joseph Merrick in Pomerance’s play. Pomerance’s play narrates Joseph’s misanthropical treatment as a result of his stepmother's carelessness and repulsion for Joseph. Also, Kafka's novella narrates the Marxist exploitation and self-alienation from the family that Gregor Samsa faces because his work contains no purpose. Whereas Langelaan's story exemplifies Andre's self-inflicted murder and transformation impairs and limits his ability to speak and write correctly."
See how the use of transitions is reflected across? You can use many transitions to add information, start a paragraph, or conclude a paragraph.
