An outline is a structured plan that helps organize ideas and information before writing a document, such as an essay or report. It typically includes main topics, subtopics, and supporting details, allowing the writer to see the overall flow of their work. By using an outline, writers can ensure that their thoughts are clear and logically arranged, making the writing process smoother. Creating an outline can also save time and reduce stress. For example, students often use outlines when preparing for assignments in school, such as essays on historical events like World War II or scientific topics like climate change. This method helps them stay focused and cover all necessary points effectively.
