A subpoint is a thought that supplements the primary theme. It generally includes information acquired from sources or other things that are vital to mention. Let's utilize "Main Point 1" from the previous example. The secondary point I made was that people need motivation in their lives to do things they may have considered impossible before. I provided two examples of people who overcame great obstacles to accomplish their goals. This information is necessary because it helps explain why my first example succeeded where the second failed. Subpoints can be used to enhance clarity or add depth to your essay. They can also help tie together different parts of your paper. For example, if you were writing an argument essay, you could use the subpoints as points in your argument structure. The most effective essays include several strong subpoints. An essay without any interesting or relevant information cannot hold our attention for long. Thus, the best essays include several strong subpoints so that readers don't feel like they're being forced to read about something they aren't interested in.
