A copy editor is a professional who reviews written content to ensure clarity, accuracy, and consistency. They check for grammar, punctuation, and spelling errors, making sure that the text adheres to specific style guides, such as the Chicago Manual of Style or AP Stylebook. Their work is essential in publishing, journalism, and any field that requires polished written communication. In addition to correcting errors, copy editors also improve the overall flow and readability of a document. They may suggest changes to enhance the structure or tone, ensuring that the content effectively communicates its intended message to the audience.
