An example of a narrative essay is George Orwell's 1938 travel piece entitled "Marrakech," wherein he recounts his experiences in Morocco. A narrative essay is one in which the writer describes a personal experience as a story.
Some techniques commonly used to this end include sensory descriptions, such as what the author has smelled, heard and saw; morals or messages, such as what the author has learned; and clear, visual language rather than abstract language.
The best narrative essays will draw the reader in with action and sequential events, often around a central theme such as rite of passage, family, conflict, success or failure.
These essays are often written from a first person perspective, with the aim of forging an intimate connection of empathy with the reader.
