Discursive Style

The discursive style is written in a more formal and impersonal style than other essays. It begins with an introduction to the topic. Each issue should be discussed in a separate paragraph and each paragraph should begin with a strong topic sentence. The essay will typically alternate a paragraph of point followed by a paragraph of counterpoint. Discursive essays often have transitional wording leading into the next paragraph. The writer may choose to either express a low-key opinion in the final paragraph or leave readers to draw their own conclusions.
