A Practical Guide to Writing Better Dialogue

Why Most Dialogue Reads Like a Transcript

Pick up a first draft and you will almost always find two characters saying hello to each other. "Hi, how are you?" "Fine, thanks — you?" "Not bad. Listen, about the thing..." It is faithful to life and fatal to a scene. Real speech is padded with pleasantries, and pleasantries on the page are dead weight.

Fiction dialogue is not a recording. It is a compression of speech, keeping the words that carry pressure and cutting the rest. Readers do not need to watch a conversation begin in order to believe it happened; they need to arrive at the moment it becomes interesting.

So try this. Delete the first three lines of any exchange and see whether anything is lost. Nine times out of ten the scene opens sharper. Greetings, weather talk and the slow wind-up to the real subject are scaffolding — take it down once the wall stands.

  • Cut "hello" and "how are you" unless the greeting itself is charged.
  • Start mid-argument, mid-question, mid-lie.
  • Trust the reader to infer the twenty seconds you skipped.

Conflict Is the Engine, Not the Decoration

Every exchange worth reading has friction in it. That does not mean shouting. Conflict can be as quiet as one character wanting reassurance and the other wanting to leave, or a daughter asking about a holiday to avoid asking about her father's health. The point is that two people cannot both get what they want in the same breath.

Before you write a scene, answer two questions. What does each character want from this conversation? And what are they willing to do to get it? If both answers are identical and easy, the scene will sag. Give one of them an agenda the other resists — even gently — and the lines start writing themselves.

Watch out for agreement. When characters nod along, the writer is usually the only one enjoying it. Let someone misunderstand, deflect, bargain, or change the subject. Disagreement does not have to be hostile; it only has to be real.

Subtext: The Conversation Beneath the Conversation

People rarely say exactly what they mean, and characters should be no different. The surface of the exchange is the text; the real transaction happens underneath. A husband asking whether his wife remembered to lock the car may actually be asking whether she remembers anything he tells her. Neither of them says so.

To build subtext, decide what each character is protecting, then let them talk around it. Use ordinary, practical language as cover — the shopping, the parking, the dog — while the emotional stakes run hot beneath the words. The reader feels the heat even when the characters are discussing bin day.

A useful rule: if a line states an emotion directly, look for a way to make it circle the emotion instead. "I'm angry with you" is a report. "You've got the same laugh as your mother" can be a knife.

Interruption, Overlap and the Rhythm of Speech

Real conversation is untidy. People talk over each other, trail off, and answer the question they wish had been asked. You can suggest that music on the page with a few honest tools.

  • The em dash for interruption — a character cut off mid-thought, either by the other speaker or by their own reluctance.
  • The ellipsis for a faltering voice — useful, but ration it. Too many and the page looks nervous.
  • Action beats instead of tags — "she poured the tea" places us in the scene and sets the mood without an adverb.
  • Rhythm variation — a long, careful sentence followed by a three-word answer reads like a power shift.

Vary the length of speeches too. If every line runs to two sentences, the scene feels like a tennis rally. Let one character be terse and the other expansive, and the imbalance will do the characterisation for you.

Silence Does the Heavy Lifting

What a character does not say is often louder than what they do. A question met with a long pause, a subject changed, a shrug in place of an answer — these are all beats of dialogue. Treat them as lines.

Try writing a scene in which one character asks something important and the other never replies. Describe the silence in action: the kettle boiling, a coat being buttoned, a glance at the door. The reader will supply the emotion, and emotion supplied by the reader is the strongest kind there is.

Beware of filling every gap. Beginners rush to explain, adding a line of dialogue to clarify what the pause already said. Resist. If you have planted the tension properly, silence is not empty — it is loaded.

An Editing Pass You Can Run Today

Take one scene and work through it with these checks.

  • Read the exchange aloud. Anywhere you stumble is usually where characters are explaining rather than talking.
  • Cut the opening. Delete the first two or three lines and see if the scene survives.
  • Name what each character wants in every beat. If you cannot, the line is filling space.
  • Remove the adverb from every "she said". Replace it with a stronger verb or an action beat.
  • Check whether anyone is being too articulate. People repeat themselves, lose their thread, and say the wrong word.
  • Find one silence worth keeping, and stop explaining it.

Dialogue improves fastest through subtraction. Cut the greetings, let conflict do the driving, and trust your reader to hear what is not spoken.
