What Is Copy Editing?

Copy editing is the process of correcting written material for clarity, accuracy, and consistency. Copy editors ensure that content is free from grammatical, spelling, and punctuation errors and flows smoothly. Their primary goal is to improve the overall quality and readability.  Copy editing comes after structural/developmental and line editing but before formatting and proofreading.
