22.11 Grammar Review

Grammar review is the stage of the editing process concerned with verifying that a manuscript's sentences conform to the rules of standard grammar — subject-verb agreement, correct tense usage, proper pronoun case, appropriate punctuation, and sound sentence construction — and with correcting departures from those rules that are unintentional errors rather than deliberate stylistic choices.

Scope of Grammar Review

Grammar review sits within the broader copyediting stage of manuscript preparation, alongside spelling and consistency checks, but it is distinct in that it specifically concerns the structural correctness of sentences rather than their content, style, or word choice. Where line editing asks whether a sentence is as vivid or economical as it could be, grammar review asks whether the sentence is constructed correctly according to the conventions of the language it is written in, independent of how well the underlying idea is expressed.

Core Areas Covered in Grammar Review

Subject-verb agreement. Verifying that singular subjects take singular verb forms and plural subjects take plural verb forms, including in sentences where intervening phrases or clauses make the true subject less immediately obvious, such as "the collection of letters was found" rather than "were found," since "collection" — not "letters" — is the grammatical subject.

Tense consistency. Checking that verb tense remains consistent within a given narrative frame, and that shifts between past, present, or perfect tenses occur only where the timeline of events actually requires them, rather than as an unintentional slip within a single passage of continuous action.

Pronoun agreement and case. Confirming that pronouns agree in number and gender with their antecedents, and that pronoun case is correct — "she and I" rather than "her and me" in a subject position, for example — along with checking that every pronoun has a clear, unambiguous antecedent rather than referring vaguely to an idea rather than a specific noun.

Modifier placement. Identifying dangling and misplaced modifiers, in which a descriptive phrase is not positioned adjacent to the word it is intended to modify, producing an unintended or illogical meaning even though each individual word in the sentence may be used correctly.

Sentence fragments and run-ons. Distinguishing between sentence fragments and run-on sentences that are unintentional errors and those that are deliberate stylistic choices — a fragment used for rhythmic emphasis, for instance — since fiction frequently uses both forms deliberately, and grammar review in a creative-writing context requires judgment about intent rather than mechanical correction of every non-standard construction.

Punctuation mechanics. Reviewing comma usage, particularly around dependent clauses, appositives, and items in a series; correct use of semicolons and colons; consistent formatting of dialogue punctuation, including placement of commas and periods relative to quotation marks; and correct use of apostrophes in possessives and contractions.

Parallel structure. Checking that items presented in a list or series, or elements joined by coordinating conjunctions, share the same grammatical form, since a break in parallel structure — mixing verb forms or phrase types within what should be a matched series — can make a sentence read as awkward or unbalanced even when no single element is individually incorrect.

Grammar Review and Creative License

Grammar review in a fiction manuscript differs from grammar review in expository or technical writing because fiction routinely and legitimately departs from standard grammar for deliberate effect: sentence fragments for pacing, run-on sentences to convey a rush of thought, non-standard punctuation in stream-of-consciousness passages, or dialect and vernacular grammar rendered accurately in a character's dialogue. A grammar review conducted without attention to authorial intent risks "correcting" these deliberate choices into standard but flattened prose, erasing a stylistic effect the writer intended. For this reason, effective grammar review in fiction editing generally distinguishes between an error — a construction the writer did not intend and that confuses or distracts the reader — and a deviation, a non-standard construction used deliberately and consistently for a specific effect, applying correction only to the former.

Position in the Editing Sequence

Grammar review is typically performed after structural and line-level revision are complete, since sentence-level grammatical correction on material that is later cut or substantially rewritten wastes effort, and because grammatical judgment calls — particularly around intentional deviations from standard usage — are easier to make once a passage's final wording and rhythm are largely settled. It commonly overlaps with, or immediately precedes, a broader copyediting pass and is generally understood as one component of that larger stage rather than a fully separate step in the editing process.
