As texts, essays are classified into narrative essays, persuasive essays, expository essays, etc. according to their purpose. In this way, an essay is expository if it provides information about a specific topic, this means it focuses on explaining or illustrating something. This differs from a narrative essay that describes a story or experience, from a persuasive essay that tries to convince the reader about an idea and from a reflective essay, in which the author reflects about something. This implies it is in an expository essay the author only imparts or provides information about a topic.
