Copyediting and line editing are two different types of editing processes that require different skills and expertise. Copyediting involves the review and correction of a text for grammar, spelling, punctuation, and general readability. Line editing goes a step further, delving into issues like sentence structure, word choice, pacing, and transitions. It also involves making sure that characters and plot lines are consistent, that dialogue is natural, and that the overall arc of the story is effective. Both copyediting and line editing are essential to putting together a quality manuscript, so it's important to understand the difference between them.
