<span>Expository
essay writing provides facts, considers ideas, describes processes or
events, or analyzes themes, arguments, or other works that can be
interpreted. This essay must start with a strong introductory paragraph
that contains a thesis statement. The thesis statement should be clear,
short, and well-defined. Remember, the thesis statement is the writer’s
major point, argument, or essential idea and should be cautiously
narrowed to explain where the essay is headed.</span>
Try starting with a simple outline to organize your thoughts so you don't get confused it may be easier to actually write the body paragraphs before any introduction or conclusion so you can correspond your thoughts in your body paragraphs with your introduction and conclusion but it depends on who you are and what you prefer
