When analyzing and writing about literature, consider your foundation text(s): the fairy or folk tale. What aspects of the text interest you? Theme? Characters? Plot? Style? Explore and learn about those aspects of the foundation text. For example, many fairy tales have stock or stereotypical characters whose traits and depiction are a reflection of the time and place, the society in which the tale is told.
Next explore ideas that may intersect with the text, ideas that may have more to do with society, social norms, history, religion, or philosophy.
Find the intersection between the text(s) and the external ideas.
Formulate or develop a thesis that makes a claim about the intersection of the aspect of the foundation text that captures your interest and the external ideas.
