Editing, proofreading, and revise are all different stages of the writing process.
Editing is the process of making sure your writing is free of errors and is clear and concise. This usually happens after you’ve written a first draft.
Proofreading is the process of checking your writing for errors, such as Grammatical, punctuation, and spelling mistakes. This usually happens after you’ve edited your work.
Revising is the process of making changes to your writing, such as improving the structure, the clarity, and the overall quality of your work. This usually happens after you’ve written a first draft and edited it.
