A paragraph is a portion of the essay that discusses one idea in detail and supports the thesis or main idea of the essay.
The thesis should be a clear, one-sentence explanation of your position that leaves no doubt in the reader’s mind about which side you are on from the beginning of your essay.
If yours is much longer you might want to consider editing it down a bit!
Here, by way of example, is an introductory paragraph to an essay in response to the following question: "Do we learn more from finding out that we have made mistakes or from our successful actions?
Proper essay and paragraph format helps to achieve unity and coherence and enhances the reader’s understanding.
Using well-worded topic sentences and concluding sentences will help maintain unity and coherence throughout the essay.
