In both academic writing and professional writing, your goal is to convey information clearly and concisely, if not to convert the reader to your way of thinking. Transitions help you to achieve these goals by establishing logical connections between sentences, paragraphs, and sections of your papers. In other words, transitions tell readers what to do with the information you present to them. Whether single words, quick phrases, or full sentences, they function as signs that tell readers how to think about, organize, and react to old and new ideas as they read through what you have written.
Transitions signal relationships between ideas—relationships such as: “Another example coming up—stay alert!” or “Here’s an exception to my previous statement” or “Although this idea appears to be true, here’s the real story.” Basically, transitions provide the reader with directions for how to piece together your ideas into a logically coherent argument. Transitions are not just verbal decorations that embellish your paper by making it sound or read better. They are words with particular meanings that tell the reader to think and react in a particular way to your ideas. In providing the reader with these important cues, transitions help readers understand the logic of how your ideas fit together.
