The conventions are published, and they are narrower than they look

In novels and stories, words spoken by a character are normally set off from the narrative with quotation marks. The speaker is identified in the run of text by a tag such as "she said". A new paragraph traditionally begins when the speaker changes.1 Where a line of dialogue is followed by a tag, the dialogue ends with a comma, the comma sits inside the closing quotation mark, and the first word of the tag is lowercase.

The Chicago Manual of Style distinguishes that case from a second one. A comma follows verbs such as said, replied, or asked when the sentence is simply identifying a speaker. Punctuation is omitted where a quotation introduced midsentence forms a syntactical part of the surrounding sentence, as in a sentence reporting that she said she would "prefer not to comment".2

Interruption and hesitation have their own conventions, and they are different from one another. Speech cut off midsentence takes an em dash. Speech that falters or trails away takes an ellipsis instead. Where the narrator describes an interrupting action in the middle of a spoken line, the dashes go outside the quotation marks rather than inside them, so that the spoken words remain continuous.3 Neither convention takes an additional mark to close the quotation.

Which of these an author can override, and on what basis

Chicago's own editors are explicit that the manual does not exhaust the possibilities open to creative writers, and they advise querying thoughtfully rather than enforcing a stylebook automatically.1 The eighteenth edition, published in 2024, expanded the manual's coverage into fiction and other creative genres, including punctuation and dialogue, after decades of concentrating on nonfiction.4

The same editors record that dialogue has been presented without quotation marks for centuries. Removing the marks takes away a layer of artifice between reader and narrator, at some cost to clarity. Some books use the convention of drama instead, with a speaker's name followed by a colon.1 Any of those is a legitimate choice, and none of them is an error.

The distinction that matters is between a system and an accident. A novel that omits quotation marks throughout has made a decision. A novel that omits them in chapter four has made a mistake, and only a reader holding the whole manuscript can tell the two apart.

Speech tags and action beats are punctuated differently

A speech tag identifies who is speaking. An action beat describes what a character does. The first is grammatically part of the sentence containing the dialogue and is joined to it with a comma. The second is its own sentence, so it takes a period and a capital letter.

The line between them is not always sharp. Chicago's editors have written about the awkward middle case, where a word such as "muttering" behaves less clearly as a speaker tag than "said" does, which makes the comma harder to place.2 Where a manuscript is inconsistent about that middle case, the useful editorial response is a query rather than a silent correction, because the author may hear the line one way rather than the other.

Consistency is the checkable part, and it is recorded rather than remembered

Almost everything else an editor does to dialogue is verification. Repeated description, contradictory physical detail, and a character introduced twice are trackable across a manuscript, and copy editing covers checking mechanical consistency and building the style sheet that records the decisions taken.5

Dialect and idiosyncratic speech benefit most from that record. Whichever system a book uses for contractions, dropped letters, and apostrophes, it needs to be one system applied evenly. An editor writes the spellings down and applies them throughout, which is a matter of record-keeping rather than a view about the writing.5 The style sheet is also what tells a proofreader, months later, that an unusual spelling on page 300 was approved on page 40.

Editors Canada places the wider judgment elsewhere. Stylistic editing is defined as editing to clarify meaning, ensure coherence and flow, and refine the language, and maintaining consistent tone and authorial voice is one of the tasks listed under that heading.5 Preserving how a character sounds is part of the work rather than a courtesy extended alongside it.

Everything a client sends is treated in confidence, including unpublished manuscripts and works in progress. EditFast marks what is inconsistent, what departs from the manuscript's own conventions, and what a reader is likely to misread. What a line of dialogue is meant to reveal, and whether a character would say it at all, belongs to the novelist.

A novelist who knows which of the forty decisions on a page are rules can spend the argument on the other few. Those are the ones worth arguing about.
