Using "First" as a signal word in an expository essay is effective because it clearly indicates the beginning of a sequence in a process. When explaining a process, it is important to guide the reader through each step in a logical order. "First" establishes that what follows is the initial stage or action in the series of steps that make up the process being described.

When you use "First," it helps set the foundation for the reader, as it prepares them to follow the subsequent steps, which might be marked with words like "Next" or "Then." This approach enhances clarity and makes it easier for readers to understand and follow the progression of ideas or actions you are presenting. The logical flow created by using "First" is essential in process writing, where order and clarity are paramount for comprehension.
