Writing Tips: What Editors Keep Flagging in Manuscripts

Working editors flag the same manuscript habits again and again: mechanical inconsistency, structural problems they query but never fix, and facts that will not hold.

The same notes come back with most first manuscripts: mechanical slips, shaky structure, and facts that do not hold. The Chicago Manual of Style describes editing work as running from mechanical corrections to remedial work on baggy prose. Most copy editing jobs fall into one of three levels: light, medium, and heavy.

The pattern is old, and it is fixable. Editor notes cluster around a short list of habits. A writer who knows the list can clear much of it before anyone else reads a . The trail runs from the first to the final proof.

What Gets Marked First

Mechanical consistency comes first. According to Einsohn, cited in a standard survey of copyediting, mechanical editors chase abbreviations, capitalization, hyphenation, italics, numbers, punctuation, quotations, and spelling. None of it is glamorous. All of it is visible. An editor who fixes every comma has less time for the story.

Consistency is the operative word. A text can follow any defensible rule, but it must follow one rule. Editors flag the third spelling of a character's name faster than the first. House style settles most disputes, which is why publishing houses keep style guides close. Even one consistent choice, applied everywhere, removes a whole class of marks.

Why Editors Query Instead of Rewrite

Copy editors flag structural and organizational problems, but they do not fix them. The fix belongs to the author. Editors are also asked to respect a writer's preference when it is defensible, since a style choice is not an error. The note in the margin asks a question, and the answer stays with the writer.

That respect runs both ways. Grammar guides disagree with each other, and some writers hear a correction as an attack. The workable habit, per the survey, is to enforce firm rules and leave defensible choices alone. A manuscript with consistent choices invites fewer fights.

What Editors Flag Beyond Grammar

Credibility. Copy editors are not fact-checkers, yet they comment on anything they know to be untrue, such as year discrepancies. They must also point out biased language, including material that might form the basis for a lawsuit alleging libel or invasion of privacy. Those notes protect the writer as much as the publisher. We covered a connected angle in How a Book Advance Actually Gets Paid Out.

Then there is the larger shape. The Manual's phrase for the deep cases is remedial : disorganized passages, muddled tables, clarity itself. Notes at this level read as questions about order. A writer who reshuffles chapters before submitting, rather than after, spares the hardest round of marks. Deep notes cost the most. They arrive late and change the whole build.

Who Reads Before an Editor Reads

Unsolicited manuscripts land in the slush pile, and the sifting falls to editorial assistants or outside first readers. If a first reader finds something worth keeping, a senior editor takes a look. Many houses now refuse unsolicited work. Doubleday stopped taking it in the early 1980s, citing time and physical resources.

The rejection numbers are harsh and documented. Stephen King's Carrie collected thirty refusals before its 1974 publication and bestseller run. J. K. Rowling's first Harry Potter manuscript drew roughly twelve. William Golding's Lord of the Flies gathered twenty. The pile still yields: The Hunt for Red October came straight out of the Naval Institute Press slush pile, and Ordinary People was Viking's first slush acceptance in twenty-seven years.

Conclusion: Notes Point at the Reader

The repeat flags share one root: they interrupt a reader. A misspelled name pulls the eye, a broken order stalls the plot, an unverified date plants doubt. Editors mark interruptions because readers feel them. A writer who reads a manuscript once as a stranger, checking consistency, order, and proof, has already settled most of the editor's notes. The habit costs an hour. It saves weeks of marks.

Frequently Asked Questions

What is the difference between light, medium, and heavy editing?
The three levels describe how deep the intervention goes. A light pass covers surface mechanics, a medium pass reworks sentence-level style, and a heavy pass reaches organization and clarity. The publisher chooses the level based on budget and schedule, and the chosen level sets the copy editor's priorities for the manuscript.
Why does an editor query a problem instead of fixing it?
Structural and organizational problems belong to the author. A copy editor is expected to point out a disorganized passage or a gap in argument, but not to rewrite it. Queries also respect voice: where a choice is defensible, the editor leaves it, since enforcing firm rules matters more than uniform taste.
Are slush pile rejections a verdict on a writer's ability?
No. The slush pile is filtered by assistants and first readers under heavy volume, and many houses refuse unsolicited work outright. Documented careers argue against despair: Stephen King's Carrie was rejected thirty times, William Golding's Lord of the Flies twenty, and The Hunt for Red October was found in a slush pile.
