Parallel structure has many different effects on writing. For example, parallel structure helps you communicate ideas more clearly by allowing a text to be more readable and clear. It also helps emphasize key ideas by highlighting the most important ideas through the tone it creates. Finally, one of the most important contributions of parallel structure is that it creates a verbal rhythm that allows the reader to read more effectively and increases the persuasiveness of the text.
