The introduction of an essay is the first thing that readers see, so it should be engaging and interesting. It should provide a brief overview of the main points that will be discussed in the body of the essay. The introduction should also include a thesis statement, which is a single sentence that summarizes the main argument or point of the essay. The introduction should also set the tone for the rest of the essay, and should be written in a way that captures the reader’s attention and makes them want to keep reading.
