Identify the central theme for your allegory by stating your point clearly and listing the elements that define your theme and make it significant. For instance, you may decide to write an allegory about the virtue of individuality, and you decide that the elements of individuality are the ability to surpass expectations, grow as a person and become more than your base function. Develop your theme until you have listed numerous elements that are relevant to your theme.
Outline a story that utilizes these elements in an original way by describing the story you wish to tell and then organizing it into specific sections that build into a climax. Make sure that each section is significant to your theme and builds your ideas as your story goes. As an example, you may decide to tell a story about a father and son fixing a car engine and use the order of the engine to represent the element of social order that is counter to individuality. Describe ways you can make this connection throughout your allegory.
Assign additional allusions to the theme of your story. Make sure that your allusions refer to your theme and carry the aspect of your theme the way you intend. For instance, you want the engine in your story to demonstrate the limitations of order, so describe the engine as deteriorating, eroding from years of uniform service and use the boy in your allegory to question what the engine would need to keep from deteriorating.
Develop your allusions as you move from point to point by transitioning your dialogue through important questions about your primary theme. As an example, the boy in your story may question why engines erode before his father explains that they cannot grow, develop or improve, they can only stagnate where they sit. Choose powerful descriptors to explain the development of your theme, such as using the word "stagnate," significant to the idea of personal growth.
Conclude your narrative allegory by wrapping up your discussion with a simple idea that you reader can take with him. For instance, the boy in your story may ask his father what would happen if the engine parts could grow on their own and his father may respond with: "Just imagine where it could take us then." Use potent statements that clearly suggest the point you intend with the story.
Read your allegory from the beginning and look for errors made during your writing process, such as spelling, grammar or formatting errors. Correct any errors that you find. Reread your allegory again, focusing on your theme and making sure that you have conveyed your theme throughout your narrative.
