Editing involves assessing the effectiveness, accuracy, and appropriateness of the words and sentences in a document. Before you begin to edit, remember that editing focuses on your document’s words and sentences, not on its overall structure or ideas. If you’re uncertain about whether you’ve organized your document as effectively as possible or whether you’ve provided enough support for your argument, deal with those issues first. In the same way that you wouldn’t start painting a house until you’ve finished building the walls, hold off on editing until you’re confident that you’re finished revising.
