22.12 Punctuation Review

Punctuation review is the stage of manuscript editing focused specifically on verifying that punctuation marks are used correctly and consistently throughout a manuscript, governing how commas, periods, semicolons, colons, dashes, quotation marks, apostrophes, and other marks are deployed to structure sentences and signal meaning that word choice and sentence structure alone cannot fully convey.

The Function of Punctuation in Prose

Punctuation performs work that is largely invisible when done correctly and disruptive when done incorrectly. A comma placed or omitted incorrectly can change which words in a sentence modify which other words, can create an unintended pause or run words together that need separation, or can alter meaning entirely, as in the difference between "let's eat, Grandma" and "let's eat Grandma." Because punctuation operates below the level of conscious attention for most readers during a smooth read, errors in punctuation tend to surface as a vague sense that a sentence is hard to follow, rather than as an immediately identifiable problem, which makes a dedicated review pass necessary to catch issues that might otherwise be misattributed to weak sentence construction.

Areas Covered in Punctuation Review

Comma usage. This includes commas separating items in a series, commas setting off introductory phrases and dependent clauses, commas around non-restrictive appositives and parenthetical elements, and the comma splice, in which two independent clauses are joined by a comma alone without a coordinating conjunction, which is treated as an error in standard prose though it appears deliberately in some stylized fiction for rhythmic effect.

Dialogue punctuation. Fiction manuscripts require particular attention to dialogue formatting: commas and periods placed inside closing quotation marks in standard American usage, question marks and exclamation points placed inside or outside quotation marks depending on whether they belong to the quoted speech or the surrounding sentence, and correct punctuation of dialogue tags, distinguishing a tag such as "she said" from an action beat such as "she frowned," which take different punctuation before the closing quotation mark.

Semicolons and colons. Semicolons joining two related independent clauses without a coordinating conjunction, and colons introducing a list, explanation, or elaboration following a complete independent clause, are reviewed for correct usage, since both marks are frequently used incorrectly to join a fragment to a clause or are used interchangeably with commas despite serving distinct grammatical functions.

Dashes and hyphens. Em dashes marking an abrupt break, an interruption, or a parenthetical aside are reviewed for consistent formatting — with or without surrounding spaces, depending on house style — and are distinguished from en dashes, which typically indicate a range, and from hyphens, which join compound words and modifiers; inconsistent use of these three visually similar marks is a common target of punctuation review.

Apostrophes. Correct formation of possessives, including singular possessives, plural possessives, and possessives of names ending in "s," is checked alongside correct use of apostrophes in contractions, since confusion between possessive pronouns that do not take an apostrophe — "its," "theirs," "whose" — and contractions that do — "it's," "there's," "who's" — is one of the most common punctuation errors in manuscripts.

Ellipses and interruption marks. The distinction between an ellipsis, indicating trailing off or an omission, and an em dash, indicating an abrupt interruption, is reviewed for consistent and correct application, particularly in dialogue, where the two marks signal meaningfully different things about how a line of speech ends.

Consistency as a Component of Punctuation Review

Beyond correctness according to standard grammatical rules, punctuation review also addresses internal consistency within a manuscript, since some punctuation choices — spaced versus unspaced em dashes, the use of the serial comma before the final item in a list, single versus double quotation marks depending on regional convention — are matters of house style rather than fixed rules, and different choices can each be valid so long as they are applied uniformly throughout the manuscript. A style sheet recording these decisions, typically produced during copyediting preparation, is used during punctuation review as the standard against which consistency is checked.

Punctuation Review and Stylistic License

As with grammar review more broadly, punctuation review in a fiction manuscript must distinguish between unintentional errors and deliberate stylistic choices. Unconventional punctuation is used deliberately in some fiction to render a character's fragmented thought, an unpunctuated stream of consciousness, or a distinctive narrative voice, and a punctuation review conducted without regard to the writer's evident intent risks correcting these deliberate choices into standard but flattened punctuation that no longer serves the passage's purpose. Effective punctuation review therefore evaluates whether a non-standard usage appears consistently and purposefully within its context, treating it as an intentional device when it does, and as an error requiring correction when it appears inconsistently or without any apparent stylistic function.
