Everything we write has a specific structure. A text message is short and filled with slang, an email is formatted like a letter, and an essay is in formal paragraphs. These various structures contribute to the overall meaning or message of the writing. Think of structure as how the parts in a piece of literature are put together.
Authors will carefully consider the structure of every piece of writing because changing the parts will change the whole message. For instance, having slang in a formal essay will undoubtedly make the writing less serious.
Two types of literature that have specific structures are poetry and drama. Let's look at the structure of both poetry and drama to analyze how it contributes to the author's message.
