The word “Essay” is derived from the Latin word “Exagium“, which means to present a problem in simple terms. The essay definition in this regard would be something like “This is a small piece of writing that expresses the opinion of an author. As well as the expression of information on a topic, idea or event.” An essay can express ideas on literature, science, religion, technology, medicine, society, or any other topic.
