Body - ‘Say It’

The body paragraphs are where the writer unloads their information. Explain the topic or concept thoroughly. Make sure to use reliable references to solidify your point. Expository essays are often assigned in-class or on exams. Therefore, professors expect students to write fast and pick references from their head.
