Proofreading is the process of reviewing written text to identify and correct errors in grammar, spelling, punctuation, and formatting. It ensures that the final document is clear, accurate, and free of mistakes, enhancing its overall quality. Proofreading is an essential step in writing, whether for academic papers, business reports, or creative works. This task can be performed by the original author or by a separate individual, often referred to as a proofreader. Effective proofreading requires attention to detail and a good understanding of language rules. Many people use tools and software to assist in this process, but human judgment remains crucial for nuanced corrections.
