After writers finish revising, it’s time to edit. Writers edit, or focus on CUPS, so their readers can focus on their main ideas. Grammatical errors can be distracting for readers, and sometimes grammatical mistakes can make writing confusing or hard to read for an audience. In editing, writers think about CUPS: Capitalization, Usage, Punctuation, and Spelling. Writers ask several questions during editing. Did I capitalize the first letter of months and capitalize titles of books, movies, and newspapers in my paper? Did I capitalize proper nouns, the names of people, states, and countries? Did I capitalize the pronoun “I” and the first letter of each of my sentences? Do my nouns and verbs match? (Are they singular or plural?) Did I use correct punctuation at the end of my sentences? Did I use commas, periods, colons, question marks, semicolons, exclamation marks, and quotation marks in the correct way? Did I use my resources to check my spelling? While answering these questions, writers can use editing marks to change their mistakes and make their ideas clearer for their audience.
