An introductory paragraph is the first section of an essay or written work. Its main purpose is to introduce the topic and provide background information to the reader. This paragraph typically includes a hook, which is an engaging sentence designed to capture the reader's attention, followed by a brief overview of the main points that will be discussed. In addition to the hook, the introductory paragraph often contains a thesis statement. The thesis statement clearly outlines the writer's main argument or position on the topic. This helps guide the reader's understanding of the essay's direction and sets the stage for the supporting details that will follow in the subsequent paragraphs.
