Although it should be noted that the essence of the essay is its freestyle in both language and its structure, the classical form of the essay (introduction, development and conclusion) can be used to write it.
The introduction
In this, you must captivate the reader immediately. A dynamic and easy-to-read language that quickly raises what the essay is about (thesis) will attract more attention than a slow and confusing paragraph that goes around the central idea.
So the introduction should ideally be short and direct. Writing a specific opening and not a general one guarantees that the reader will not lose the thread of the reading and will be able to understand the arguments in the development as a logical derivation of the introduction he has just read.
Short school essays require a brief introduction, and longer ones can afford to elaborate a little more on the initial ideas. In any case, a quick review of the arguments to be treated and the structure that the essay will have is possible.
The development
In this section, as the name implies, the arguments that were briefly described in the introduction are developed one by one. Each segment (paragraph) should address a single topic/idea. According to the total length of the essay, a paragraph may be sufficient to develop a plan, as can several pages for more extended essays.
In a brief essay about abortion, one of the paragraphs can deal with global statistics on the death of women in clandestine clinics, and in a more extended essay on the same topic, several paragraphs, or pages, can be used to talk about clandestine clinics in the first world and those in developing countries, of doctors who decide to collaborate in the termination of pregnancies, the state of health services offered by governments, etc.
As long as they are ideas connected by a common theme, they are part of the same segment. If they are different ideas, they should go in separate paragraphs or sections that the reader should be able to identify quickly. For less experienced writers, it is a good idea to start the paragraph with the central idea and then develop it.
In the development, examples should be offered, anticipate the reactions of the retractors of the writer’s position and give them an argument against, citing experts on the subject that support the idea of the paragraph and support the thesis with evidence. You should not provide unsubstantiated opinions.
The conclusion
The conclusions are not only a summary or a synthesis of what has already been said, but must also be fertile ground for reflection for readers. The thesis that the author developed in the body of the essay must, at this point, be clear and have been proven and supported by the information offered. For a brief essay, the conclusion should be short; for a more extended and more elaborate essay, it is worth recalling the arguments presented, point by point, being careful not to be repetitive or without taking the text dynamically.
