This document provides an overview of essay writing. It defines an essay as a short written composition expressing personal ideas or opinions. Essays have characteristics like unity, order, brevity, style, and personal touch. There are four main types of essays: narrative, descriptive, expository, and persuasive. An essay consists of an introduction with a thesis statement, body paragraphs with a topic sentence and details/examples, and a conclusion that restates the main argument. Good essay writing involves planning, brainstorming, proofreading, and adding references.
