The argumentative essay is a genre of writing that requires the student to investigate a topic; collect, generate, and evaluate evidence; and establish a position on the topic in a concise manner. Please note: Some confusion may occur between the argumentative essay and the expository essay. These two genres are similar, but the argumentative essay differs from the expository essay in the amount of pre-writing (invention) and research involved.
In writing, an argument is a way in which one proves a thesis or main idea of an essay or longer researched writing. This is often confused with writing contentious work that deliberately attacks or inflames an opposing viewpoint without support. The argument is actually the support of the main theme, and is not an opinion, and is based on facts and evidence.
