Please note that the expository essay and the argumentative essay can sometimes be confused. The two genres are very similar. It requires detailed research and extensive pre-writing. Expository essays require fewer research and are shorter in duration. Expository essays may be used to help with writing assignments or tests, such the GED/GRE.
A COMPLETE RATIONALE
It is perhaps helpful to think of essays as a discussion or debate with a friend. There would be three parts to a conversation if I wanted to talk about the causes of World War II as well as its current impact on those who have lived through this turbulent time. This would raise questions about the effects of the conflict on the lives of those who lived through it. The argumentative essay should be clear, logical, and not leave any doubts about its argument or intent.
THE FIVE PARAGRAPH ESSAY
The five paragraph approach to argumentative writing is common. The five-paragraph approach isn’t the only way to create such essays. If you think it sounds simple, it is. There is an introduction, a body paragraph, three evidence paragraphs (which may include discussion about opposing views), and finally, a conclusion.
LONGER ARGUMENTATIVE ESSAYS
Complex issues and detailed research require elaborate and detailed essays. Argumentative essays involving empirical research or multiple research sources will typically exceed five paragraphs. Assignments will often determine these factors.
