I’ll be looking not only for the misspelled, but also the misplaced—those possible misalignments in your missive and the grammar that needs tending. I will seek to gently smooth the flow of your writing and catch that overly repeated word. Copy editing is looking at your thoughts in form, and gently striving to assure that they move from the page to your reader’s understanding as cleanly and clearly as possible. Did I say I will be gentle? I promise.
This is the patient art of hunting the hidden error: the ward (word) that spellcheck thinks it has corrected, and really hasn’t; that extra space in your sentence that distracts; the misspelled name or that Capitalization confusion. You want your reader to read your work, not stumble on those minor errors. Graced by my Virgo moon (go ahead, laugh), I have a good eye for detail. We simply cannot see all of our own mistakes; a lifetime of making them myself has proven this to me.
