How to Write Killer Conversations

Conversations are the pulsating heart of any compelling narrative, whether it’s a novel, a screenplay, a play, or even a nuanced marketing campaign. They don’t just convey information; they reveal character, propel plot, build tension, and deepen thematic resonance. Weak dialogue, conversely, can flatline even the most promising premise. This guide isn’t about pleasantries or polite exchanges; it’s about crafting killer conversations – the kind that grab your reader by the collar and refuse to let go, leaving an indelible imprint long after the last word.

Forget the simplistic advice to “make it sound natural.” Killer conversations often aren’t natural in the real-world sense. Real conversations are messy, repetitive, filled with “ums” and “ahs,” and rarely advance anything significantly. Fictional dialogue is a highly stylized, concentrated version of reality, distilled to its most potent essence. It’s about strategic omission, deliberate phrasing, and the unspoken weight between words.

Let’s dissect the anatomy of magnetic dialogue and equip you with the tools to wield it effectively.

The Unseen Architect: Character Voice & Subtext

The foundation of any killer conversation isn’t just what is said, but who is saying it, and what isn’t being said.

1. Character Voice: More Than Just an Accent

Every character should sound distinct. This isn’t just about regional dialects or vocabulary, though those play a part. It’s about their unique worldview, their education, their insecurities, their aspirations, their past traumas, and their current emotional state – all subtly bleeding into their linguistic patterns.

Pacing and Rhythm: Does your character speak quickly, tripping over words in their excitement or anxiety? Or do they speak slowly, deliberately, each word weighed before release, perhaps calculating or reserved?
- Example:
  - Fast-paced, anxious: “Look, I told you, alright? I told you it wasn’t my fault, the – the wrench slipped, okay? Just, just let it go.”
  - Slow-paced, deliberate: “My fault? An interesting accusation, considering the inherent instability of the… apparatus.”
Vocabulary and Sentence Structure: A professor might use complex sentences and precise terminology. A street-smart kid might favor slang and fragmented phrases. An older, world-weary character might speak in aphorisms or clipped sentences, conveying much with few words.
- Example:
  - Academic: “The prevailing geopolitical paradigm necessitates a strategic reassessment of our diplomatic overtures.”
  - Street-smart: “Yo, G, world’s messed up, right? Gotta play it smart.”
Recurring Tics and Habits: A character who always defaults to sarcasm, or habitually deflects questions, or uses a specific catchphrase (sparingly, please, or it becomes a cliché). These should feel organic, not tacked on.
- Example: A character who always starts sentences with a skeptical “Right,” or habitually adjusts their tie when nervous. These aren’t just quirks; they are reflections of inner states.
Avoid Info-Dumping through Voice: Resist the urge to make every character a walking encyclopedia. Dialogue reveals, it doesn’t lecture. If a character needs to explain something complex, their “voice” should still be apparent in how they explain it.

2. Subtext: The Elephant in the Room

This is where dialogue truly shines. Subtext is the unspoken truth, the underlying emotion, the hidden agenda, the true meaning beneath the surface words. It’s what makes a simple exchange sizzle with tension or ache with unspoken longing. Readers are intelligent; they want to infer, to discover, to participate in the storytelling.

Hidden Agendas: Characters rarely say exactly what they mean, especially when stakes are high. They might be trying to manipulate, hide something, protect themselves, or test another character.
- Example:
  - Surface: “Are you sure you want to go through with this?” (Concern)
  - Subtext: “I’m terrified this will destroy us, but I can’t tell you that directly without seeming weak.” (Fear, vulnerability)
Unspoken Emotions: Anger, fear, love, resentment – these emotions often manifest through sharp retorts, sudden silences, changes in tone, or passive-aggressive remarks, rather than explicit declarations.
- Example:
  - Dialogue: “How was your day?” “It was fine.” (The emphasis on ‘fine’ and a slight edge in tone could convey seething anger, rather than genuine satisfaction.)
Conflict and Tension: Subtext is the engine of conflict. Two characters can be talking about the weather, but the underlying conversation is about their crumbling marriage or a shared, unresolved betrayal.
- Example:
  - “Looks like rain,” he said, staring out the window.
  - “Yes,” she replied, not looking up from her book. “It usually does, this time of year.”
  - (On the surface, innocuous. Beneath, perhaps a history of broken promises, a sense of stagnant entrapment, or a deliberate avoidance of a deeper issue.)
Show, Don’t Tell (with Dialogue): Instead of saying “He was angry,” show it through his clipped words, his refusal to make eye contact, or a sarcastic rejoinder.

The Dynamic Exchange: Conflict & Pacing

Killer conversations are rarely static. They are dynamic exchanges, often propelled by conflict and masterfully paced.

3. Conflict as Fuel: The Spark That Ignites Dialogue

Dialogue without conflict is often inert. Conflict doesn’t always mean yelling or fighting; it can be subtle disagreement, clashing personalities, different goals, mismatched expectations, or an internal struggle.

External Conflict: Characters arguing over a decision, battling for dominance, trying to expose a lie, or attempting to persuade each other.
- Example:
  - “We have to approach the investors for more capital.”
  - “Are you insane? We’re barely breaking even. We need to cut costs, not accrue more debt.”
Internal Conflict Reflected: A character wrestling with a moral dilemma, trying to justify a past action, or struggling to admit a truth. This internal struggle often manifests as hesitation, contradiction, or defensive language within their dialogue.
- Example:
  - “I… I just think… maybe it wasn’t the right time. For us. For any of it.” (Hesitation revealing internal conflict about a breakup.)
Conflict of Interest/Goal: Two characters want different things from a situation or from each other.
- Example: One character wants to confess a secret, the other wants to keep it buried. Their conversation will be a dance of pressure and evasion.
Misunderstanding: A character misinterprets another’s words or intentions, leading to escalating conflict.
- Example: “I thought you said you’d handle it!” “I said I’d look into it, not fix your entire mess!”

4. Pacing & Flow: The Rhythm of Realism (and Impact)

The speed and rhythm of a conversation significantly impact its emotional weight and reader engagement.

Rapid-Fire Exchanges: Use short sentences, quick interruptions, and minimal description to convey urgency, fear, excitement, or intense argument. This builds tension.
- Example:
  - “Did you hear?”
  - “What?”
  - “The alarm.”
  - “Where?”
  - “Warehouse eight. Now!”
Slow, Deliberate Pacing: Longer sentences, pauses, and more descriptive beats indicate reflection, sorrow, deep thought, or a character trying to choose their words carefully. This can build suspense or convey gravitas.
- Example:
  - “He… He wasn’t always like this. There was a time… a different time… when he smiled. Truly smiled.” (Pauses and ellipsis convey sorrow and recollection.)
Varying Sentence Length: Don’t let every character speak in the same cadence. Mix short, punchy lines with longer, more complex ones to create a natural ebb and flow.
Interrupting & Overlapping Dialogue (Sparing Use): In real life, people interrupt. In fiction, this can convey urgency, rudeness, or heightened emotion, but overuse makes dialogue difficult to read. Use it strategically for impact.
- Example:
  - “I told him we couldn’t—”
  - “You told him what?” Anya’s voice cut him off, sharp and cold.
The Power of Silence/Pauses: The space between lines can be as impactful as the lines themselves. A pause can convey thoughtfulness, shock, unspoken accusation, or deliberate withholding. It allows subtext to bloom.
- Example:
  - “Do you trust me?”
  - A beat of silence stretched, thick with unspoken history.
  - “I never have.”

The Precision Toolkit: Economy, Action & Revelation

Beyond the fundamental principles, killer conversations are built with deliberate intent and skillful execution of concrete techniques.

5. Economy of Language: Every Word Earned

Fictional dialogue is not a transcript. It’s a highly curated experience. Every word must pull its weight.

Cut Redundancy: Avoid characters saying things the reader already knows or repeating information unnecessarily. If a character asks “Did you go to the store today?” and the next line is “Yes, I went to the store today,” that’s flat and boring. Consolidate or eliminate.
Eliminate Filler Words: “Um,” “ah,” “like,” “you know” – these are natural in real speech but clunky in fiction. Use them only when they serve a specific characterization purpose (e.g., a nervous person, someone struggling for words).
Concise Expression: Can a character say something in five words instead of ten? Opt for the shorter, more impactful version. This tightens pacing and increases tension.
- Before: “I am really feeling quite frustrated by this whole situation that we find ourselves in right now.”
- After: “This frustrates me.” Or even just: “Furious.” (Depending on context and character.)
Dialogue Tags: Less is More: “He said,” “she asked” are usually invisible. Only vary them (“he whispered,” “she snapped”) when the manner of speaking is crucial to the meaning or emotion. Overusing varied tags pulls the reader out of the dialogue. Sometimes, no tag is needed if it’s clear who is speaking.

6. Action Beats: Anchoring Dialogue in Reality

Dialogue floating in a vacuum feels artificial. Ground it with action beats – physical actions, gestures, facial expressions, or internal thoughts – that accompany, frame, or interrupt the lines. These add realism, context, and subtext.

Reveal Internal States: A character clenching their fists while speaking, or avoiding eye contact, tells the reader more about their emotional state than a simple “he was angry.”
- Example: “I’m perfectly fine,” she said, her knuckles white where she gripped the mug.
Show Character Actions: What are characters doing while they talk? Are they pacing, stirring coffee, cleaning a gun? This adds life and can reveal their state of mind.
- Example: He leaned back in his chair, a smirk teasing his lips. “So, you finally admitted defeat.”
Propel or Inform Plot: A character handing over a key during a conversation, or pointing at a map. These actions intertwine with the dialogue to advance the story.
Break Up Monotony: Long stretches of back-and-forth dialogue can become tiring. Action beats provide visual interest and rhythm.
Avoid Over-Anxious Beats: Don’t have a character constantly nodding, shrugging, or gasping. Choose impactful, specific actions.

7. Revelation & Forward Momentum: The Purpose of Every Word

Killer conversations are rarely just chit-chat. They serve the narrative.

Reveal Character: Dialogue is one of the strongest methods for characterization. What a character says, how they say it, and what they don’t say, all paint a picture.
- Example: A character who always talks about money and possessions reveals their materialistic nature. One who talks about justice or helping others reveals different values.
Propel Plot: Conversations should move the story forward. A key piece of information is exchanged, a decision is made, a new conflict arises, or a plan is hatched.
- Example: “The schematics are encrypted. We need Dr. Albright to crack them.” (Reveals a new obstacle and a potential solution, pushing the plot.)
Build World: Dialogue can subtly expose details about the setting, culture, or historical context without resorting to lengthy exposition dumps.
- Example: “You still remember the old ways, don’t you, before the Scouring?” (Hints at a past catastrophic event and cultural memory.)
Raise Stakes: A conversation can escalate the danger, amplify the emotional impact of a situation, or reveal the true cost of failure.
- Example: “If this goes wrong, we don’t just lose the contract. We lose everything.”
Foreshadowing: Subtle hints dropped in dialogue can prepare the reader for future events, building anticipation and a sense of inevitability.
- Example: “This feels too easy. I just hope we’re not missing something.” (A classic line that often precedes disaster.)
Advance Theme: Deeper narratives use dialogue to explore central themes. Characters might argue about morality, freedom, loyalty, or the nature of reality itself.
- Example: A debate between two characters about whether the ends justify the means directly addresses a moral theme.

The Litmus Test: Polish & Refinement

Once you have the core exchange, the real work of refining killer conversations begins.

8. Read Aloud: The Ultimate Authenticity Check

This is non-negotiable. Your ear is the best judge of naturalness – not natural in the “real life” sense, but natural in the “fictional dialogue” sense.

Catch Clunky Phrases: Words that look fine on the page can sound stiff or awkward when spoken.
Identify Repetition: Your ears will quickly flag repeated words, phrases, or sentence structures.
Gauge Pacing and Rhythm: Does the conversation flow smoothly? Does it drag? Does it feel too fast or too slow for the scene’s emotional tone?
Assess Character Voice: Do your characters sound distinct? If you read a line without a tag, can you tell who is speaking?
Uncover Exposition Dumps: When reading aloud, an info-dump will usually sound exactly like a lecture and stick out like a sore thumb.

9. Pruning and Polishing: The Art of the Edit

Once you’ve read it aloud, it’s time to ruthless cut and polish.

Cut Throatily: If a line doesn’t reveal character, advance plot, heighten tension, or reinforce theme, it probably needs to go.
Tighten: Every word, every syllable, counts. Can you say it more succinctly?
Vary Sentence Starters: Don’t let every line begin with “He said” or “She responded.” Integrate action beats or vary subject-verb order.
Check for Unnecessary Politeness: In conflict or high-stakes scenes, characters often drop pleasantries. “Please” and “thank you” can feel out of place and weaken impact.
Avoid “On-the-Nose” Dialogue: Do not have your characters explicitly state things that are already obvious or that should be conveyed through subtext. Don’t have a character say, “I am feeling very angry right now,” if their actions, tone, and sharp words already show it.
Ensure it Serves the Scene’s Purpose: Every conversation has a purpose within the larger scene. Does this dialogue achieve that purpose? If not, rework it.

Conclusion: The Conversational Crescendo

Writing killer conversations is less about mimicking reality and more about mastering the craft of strategic artifice. It’s about understanding your characters inside and out, recognizing the potent power of the unsaid, and wielding conflict and pacing with precision. It’s about making every single word earn its place on the page, pushing the narrative forward, and etching your characters into the reader’s mind.

Dialogue isn’t just words; it’s action. It’s revelation. It’s the raw, undeniable pulse of your story. Embrace the challenge, apply these actionable principles, and transform your character interactions from mere chatter into unforgettable, killer conversations. They are the engines of empathy, the catalysts of conflict, and the very soul of your narrative. Master them, and you master your story.
