If developmental and line editing fall under the “macro” category of editing, copy editing and proofreading bring up the rear with the “micro.” Copy editing, the editing most probably think of when they think of editing, is concerned with formal corrections to grammar and syntax—“the devil in the details”—and involves reviewing the text for errors in spelling, tense, punctuation, agreement, parallelism, etc.; the elimination of “weasel words;” checks for factual accuracy; the removal of redundancy; and much more. Copy editing is highly technical and objective and is the phase of the editing process wherein much of the heavy lifting is accomplished.
