| Choice | Effect on the scene | Planning use |
|---|---|---|
| New paragraph for each speaker | Removes the need to write “Louise said” or “Fernando said” every time | Make it the default for any exchange between characters; Chicago calls it the traditional convention |
| Reading the draft aloud | Gives your ears a chance to judge whether lines sound natural | Do it once the dialogue is written down, before you polish wording |
| Slang, contractions and colloquialisms | Common features of real speech, so they make speakers believable | Use them to mark a speaker, not to decorate every line |
| Realistic but not distracting | Characters feel believable and the reader stays inside the story | Cut any speech feature that draws attention to itself |
The conventions above come from the Chicago Manual of Style Q&A on dialogue and Polyphony Lit’s guide to writing natural dialogue.
To learn how to write dialogue in a story, make every line do work, give each speaker a recognisable voice, and format the exchange so readers always know who is talking. Slang helps only when it stays sparing and credible.
Slang choices belong to voice, and the hub on how to write slang in dialogue goes further into that side of the craft. The sections below start with what goes wrong, then cover purpose, voice and formatting.
What weak dialogue costs a scene
Weak dialogue costs a scene its pace, its characters and its credibility. Three failures show up most often, and each has a different cure.
- Filler slows the scene. Smekens Education puts it bluntly: effective dialogue is not filler and not chit-chat. Evalogue gives the practical rule of leaving out warmup, small talk and filler words. A greeting that changes nothing between two characters can usually go.
- Information dumps turn speech into blocks. Polyphony Lit warns that a single character rambling for a page about what is happening in the story will not produce strong writing. If the reader needs the facts, let them surface through a disagreement or a pointed question instead of a briefing.
- Interchangeable voices flatten the cast. Evalogue states that each character should have a unique way of speaking. When every speaker shares the same cadence and vocabulary, readers lose track of who is talking, and tags have to do work that the voices should do.
The cure for the first two failures is purpose, so that is where revision should begin.
Purpose and subtext: what each line must do
Dialogue earns its place by moving the story. Smekens Education advises inserting dialogue where the problem is identified, where it gets worse, and where it reaches its climax. Use that as a map of your draft: the lines at those points deserve the most care, and talk placed elsewhere should justify itself by revealing a choice or a secret.
Natural dialogue is not a transcript. The goal, as Polyphony Lit describes it, is speech realistic enough to make characters believable without distracting the reader. That means keeping the rhythm and texture of talk while dropping the stalls and repetitions that real conversation carries.
Let subtext carry the meaning
Evalogue calls subtext an elegant way of leading the reader along. A character who dodges a question, answers a different one, or goes quiet signals more than a character who explains a feeling outright. This works because the reader does the interpreting. It also protects you from the speech problem described above: a character who states everything plainly drifts toward the information dump.
Use subtext when characters have something to hide or protect. When two people simply need to exchange a fact, say it plainly and move on.
Voice: making characters sound distinct
Dialogue is voice, and distinct voices come from who a character is rather than from tags. A useful check from the Evalogue advice is to cover the speaker names in a scene and see whether you can still tell who is speaking. If you cannot, the lines need different vocabulary, sentence length or attitude.
One author writing in Writer’s Digest describes his own method as simply writing how he would talk. That works for a narrator close to the author’s own speech. For characters unlike you, you have to borrow voices from observation and research.
Region, background and word choice
Regional vocabulary is one of the clearest voice markers. Polyphony Lit points out that a British character may reach for words such as “peckish” and “chips” where an American character would choose different wording. For a group you do not belong to, it recommends watching films and reading books centered on that ethnic or national group before you imitate its speech.
The same Writer’s Digest piece offers a published thriller excerpt in which a character says “sarge” instead of “sergeant”. The clipped form tells the reader something about familiarity and place without a word of description. Look for that kind of economy: a single shortened word can do the work of a paragraph of characterisation.
Slang, used sparingly and credibly
Slang is part of real speech, so a few well-chosen terms make a character sound like a person from somewhere. Treat it as a tool for marking one speaker, not as a coat of paint over the whole cast. A slang term that belongs to a particular age group, town or workplace works better when only the characters from that world use it.
Credibility depends on where the words come from. Evalogue urges writers to carry a notebook and listen for local slang, which keeps your terms tied to what people actually say. Writer’s Digest gives matching advice: learn the dialect of the region your book takes place in. Words that you could not place in a real mouth, or that would date the scene awkwardly, are better left out. Plain wording beside two or three precise terms reads as more believable than a dense run of invented jargon.
Formatting rules for punctuation and tags
Clean formatting lets readers follow who speaks without effort. The conventions below combine the Chicago Manual of Style guidance, whose dialogue answer relies on the 18th edition (2024), with practical advice from writing teachers.
Paragraphs and speakers
- Start a new paragraph for each new speaker. Chicago calls this traditional, and Evalogue puts it in plain terms: each time someone starts to speak, it appears on its own line.
- Keep the pattern even in fast exchanges. Short lines on separate paragraphs are what let you drop most tags, because the layout itself shows the alternation.
- Treat the convention as a default. Chicago notes that experienced writers break the rule when it gets in the way, so follow it until you have a specific reason not to.
Quotation marks and punctuation
- Quote only what is spoken. Smekens Education says only the words that come out of a character’s mouth go inside quotation marks. Narration and action beats stay outside.
- Put periods inside the closing mark. Evalogue gives this rule for spoken lines: enclose what was said in quotation marks, with periods inside them.
- Keep tags outside the quotes. Smekens Education identifies speaker tags, also called attribution, as the words that sit outside the marks.
Tags and beats
- Default to plain verbs. According to Evalogue, words such as “said” and “asked” are basically invisible and do not catch the reader’s attention. Elaborate substitutes pull the eye away from the speech.
- Skip the tag when the speaker is obvious. Evalogue notes that you do not need a speech verb with every line if it is clear who is speaking. A tag-free line in a two-person exchange often reads best.
- Add a tag when a voice alone will not settle it. If a third speaker joins or the paragraph break is not enough, place a plain tag or a short action beat near the start of the line.
Revising with the read-aloud test
Reading the finished dialogue aloud is the most dependable revision step. Polyphony Lit says reading dialogue out loud after you have written it gives your ears a chance to judge, and the Writer’s Digest author recommends the same step. Awkward rhythm, stiff phrasing and speech nobody would say tend to show up when you hear them.
When a line sounds wrong, ask which problem it is. A line that sounds empty is probably filler. A line that sounds like another character probably needs a different word level. A line that sounds too neat may be explaining what subtext should carry. Fix the cause, then read it again.
Cutting speech down to what matters is a skill that transfers to other forms. An opening line has to earn attention quickly, as in How To Start A Hook For An Essay: 7 Smart Openers That Grab Attention Fast – Slanguagestudio, and a very short poem makes every word count, as shown in How to Write a Haiku: A Simple Step-By-Step Guide To Crafting Evocative 3‑Line Poems (2026) – Slanguagestudio.
Frequently asked questions
Can a speaker’s words stay inside a narrative paragraph?
Yes, but only in a limited case. Chicago allows a line to go straight into the paragraph as long as the person saying it was the last person mentioned. Otherwise, start a new paragraph for the new speaker.
How do I show a character’s thoughts next to spoken lines?
Polyphony Lit suggests internal thoughts, which are often marked with italics. That keeps them visibly separate from speech and from the quotation marks that belong only to spoken words.
Should I spell an accent phonetically?
Use it with caution. Evalogue warns that phonetic spellings can seem condescending. Word choice, rhythm and regional vocabulary usually signal an accent with less risk.
How much dialogue should a story contain?
Polyphony Lit advises short amounts of dialogue in most prose, with plays and screenplays as the exceptions. Speech between characters should enhance a piece rather than anchor it.
