A copy editor is a professional who reviews written content to improve its clarity, accuracy, and overall quality. They check for grammatical errors, punctuation mistakes, and inconsistencies in style. Their work ensures that the text adheres to specific guidelines, such as those set by a publishing house or a particular style manual like the Chicago Manual of Style. In addition to correcting errors, copy editors also focus on enhancing the flow and readability of the text. They may suggest changes to sentence structure or word choice to make the content more engaging for readers. This role is essential in various fields, including journalism, publishing, and marketing.
