An opinion paragraph follows the typical structure of an introductory topic sentence stating the opinion, supporting details that provide reasons and evidence to back up the opinion, and a concluding sentence that restates the main idea. While this basic structure is the same, an opinion paragraph requires persuasive arguments in the supporting details and a conclusion that echoes rather than introduces new information. Convincing evidence like facts and clear examples are needed to justify the stated opinion to the reader. Organization, coherence, and effective writing techniques are also important to maintain a unified paragraph.
