When we talk about an argumentative essay in the introduction the work is presented and the thesis is exposed. A thesis in an argumentative essay is similar to the scientist’s hypothesis. It is an idea, an affirmation, that we will defend throughout the body or development of the essay. This thesis is defended with arguments that do not have to be scientific, they can be subjective opinions.

In an expository essay, the introduction has the basic purpose of capturing the reader’s interest in the essay’s argument. Although this is evidently sought in all the trials that are carried out in this case, it is the basis of this presentation part.

When we carry out an essay of literary analysis in the introduction, we put the reader in antecedents about the work that we are going to treat and we place the concrete aspect of this one that we want to analyze in our essay.


The development of an essay is already the entry in matter, here the own expositions on the subject are presented as well as the support of theoretical referents of authority in the same one. Within development, ideas must be coherently interwoven.

It is the most fundamental of the parts of an essay since it is where we relate the content we want to show the reader. It is also known as body or development and the parts of an essay are always the longest.

Start with the approach and argued about the chosen theme and you can return to the questions made in the introduction and add new ones that allow us to make a theoretical construct of the path we are going to travel.

You can consider the ways in which the topic has been addressed by other authors and even refer if we agree or not always under solid and well structured arguments.

This part of the essay usually develops freely, it is the author who usually determines the way of presenting his ideas. The essay, because it is a type of text that mixes the expository with the argumentative, allows the writer to present his ideas while developing them between arguments.

For this reason, the essay is a direct construction and is a deep exercise of human thought. It shows the author’s way of thinking and is written once enough information has been gathered about the chosen topic, not the other way around.

The development according to the type of test

In a scientific essay we expose all the tests to which we submit our thesis, whether test / error, comparisons with other theories, used bibliography or any other type of material that proves or refutes our hypothesis. The more data we contribute, the more solid the hypothesis will be if it is confirmed.

In the argumentative essays we defend our thesis based on our opinions, on other opinions that are worth to defend ours or we try to dismantle contrary arguments to revalue our point of view. If we use other people’s ideas, it must always be clear who is responsible for them and where we have extracted that reference.

If what we are doing is an expository essay, the body of the essay is precisely that exposition of facts, narrated in a coherent and as linear way as possible. While in an argumentative essay the author may sometimes get lost in his thoughts and reflections, in this type of essays a clear line of exposure must be followed.
