Final answer:
The first time you use an author's name in your essay, you should use the author's last name.
Step-by-step explanation:
The first time you use an author's name in your essay, you should use the author's last name.
It is common practice in academic writing to refer to authors by their last name. This helps to establish their credibility and avoids confusion with other individuals of the same first name. For example, if you are writing an essay about a book written by J.K. Rowling, you would refer to the author as 'Rowling' in your first mention. Subsequent mentions can use the last name alone or be accompanied by the first name or initials if needed for clarity.
Using the author's last name is also a way to show respect for their work and expertise. It is important to be consistent in your usage throughout the essay to maintain clarity and professionalism.
