A topic outline is built around your rough outline. It organizes the order and flow of each your essay's body paragraphs. Start by relisting the supporting points of your thesis and label each point with a roman numeral. Once you've labeled each point with a Roman numeral, develop at least two sub-points, labeled A, B and C, etc, under each major point. Sub-points are specific statements that directly reflect and support each main point.
