Proofreading and editing are important steps in the writing process. Proofreading involves checking for errors in grammar, spelling, punctuation, and formatting. Editing goes beyond that and focuses on improving the overall clarity, coherence, and effectiveness of the writing. It includes revising sentences, restructuring paragraphs, and enhancing the flow of ideas. Both proofreading and editing help ensure that a piece of writing is polished and error-free.
