Although many people use the terms interchangeably, proofreading and editing are different. When a document is proofread, it is typically adjusted for surface-level errors such as grammar, punctuation, and spelling. When a document is edited, it is checked more extensively. For example, in addition to grammar and punctuation, other features such as overall organization, logical flow, clarity of ideas, style (wordiness, word choice, register), and format (APA, MLA, CMS) will be considered.
