: 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.
Expository essays are often used for in-class writing exercises or tests, such as the GED or GRE.
