7 Common Dialogue Writing Mistakes That Reveal a Rookie Novelist (And How to Fix Them)

On The Table Read Magazine, “the best arts and entertainment magazine UK“, master the art of natural speech and elevate your storytelling by discovering the seven dialogue writing mistakes that pull readers out of your novel—and exactly how to fix them.

A novel’s pacing, tone, and character dynamics live or die by its dialogue. Strong dialogue pushes the plot forward and reveals deep character subtext without relying on heavy exposition. Weak dialogue, however, acts as an immediate red flag to readers, editors, and literary agents, pulling them right out of the fictional world.

A breakdown of the seven most common dialogue mistakes rookie novelists make, along with the concrete techniques needed to fix them, provides a clear path forward.

1. The “As You Know, Bob” Exposition Dump

One of the most frequent errors in early drafts is using characters to feed background information to the reader. This occurs when two characters discuss facts they both already know, purely for the sake of catching the audience up on the plot.

• The Mistake: “As you know, Bob, since our mother died in that mysterious boating accident five years ago, we’ve had to run this family bakery completely by ourselves.”
• Why It Fails: Real people do not vocalize shared history in casual conversation. It feels artificial and breaks the illusion of reality.

How to Fix It: Use Subtext and Emotional Friction

Instead of spelling out the backstory, allow the characters’ actions and emotional tension to hint at the past. Let the reader do a little bit of detective work.

• The Revision: Bob slammed the flour scoop onto the counter. “We can’t keep doing this alone, Sarah. Five years of twelve-hour days. I’m exhausted.” Sarah looked at the fading photograph of their mother hanging by the oven, her thumb tracing the edge of the frame. “We don’t have a choice,” she whispered.

2. On-the-Nose Dialogue (Zero Subtext)

In real life, people rarely say exactly what they are thinking or feeling. We speak around our issues, mask our insecurities with humor, or use politeness to hide anger. Rookie dialogue often lacks this layer, making characters say precisely what is on their minds.

• The Mistake: “I am incredibly angry at you because you forgot our anniversary, and now I feel unloved and secondary to your career.”
• Why It Fails: It strips away all tension. When characters are entirely transparent, the scene loses its psychological depth.

How to Fix It: The “Iceberg” Method

Keep the true meaning of the conversation underwater. Let the characters argue about something minor (like dinner or car keys) to express a much larger conflict.

• The Revision: He dropped his keys on the counter. “Sorry I’m late. Traffic on the M6 was a nightmare.” She didn’t look up from her book, turning a page with a sharp, crisp snap. “The reservations were for eight. I threw the chicken out twenty minutes ago.”

3. The Thesaurus Tag Trap

New writers often worry that repeating the word “said” will bore the reader. In an attempt to vary their prose, they turn to heavy, melodramatic dialogue tags.

• The Mistake: “Don’t go in there,” she ejaculated. “Why not?” he queried. “Because it’s dangerous,” she bellowed.
• Why It Fails: Words like remonstrated, declared, intoned, or gesticulated draw attention away from the spoken words and focus it on the mechanics of the writing.

How to Fix It: Treat “Said” as Invisible (Or Use Action Beats)

The word “said” is functionally invisible to readers; the human brain skips right over it, focusing instead on the dialogue itself. Even better, replace tags altogether with active body language—known as action beats—to ground the characters in the physical space.

• The Revision: “Don’t go in there.” She grabbed his forearm, her grip tightening until her knuckles turned white. “Why not?” He tried to pull away, but stopped when he saw the look in her eyes. “Because it’s dangerous.”

4. Perfect, Flawless Grammar and Syntax

When people speak, they rarely use perfectly structured, grammatically flawless sentences. They use fragments, run-on sentences, slang, and contractions. Writing fictional dialogue exactly like an academic essay makes characters sound like robots.

• The Mistake: “I cannot believe that you would suggest that we go to the cinema tonight. I do not have the time because I must finish my homework assignment.”
• Why It Fails: It lacks the natural cadence, rhythm, and breath of genuine human speech.

How to Fix It: Lean Into Contractions and Truncations

Unless a character is intentionally written as rigid, aristocratic, or non-native to the language, use contractions (can’t, don’t, I’m, wouldn’t) and allow sentences to break apart naturally.

• The Revision: “Cinema tonight? No chance. I’ve got to finish this assignment or Professor Hayes will kill me.”

5. Phonetic Accents and Dialect Overload

Trying to capture a character’s regional background by spelling every single word phonetically is a massive barrier to readability. It forces the reader to slowly translate the text rather than enjoy the story.

• The Mistake: “Y’all outta see ’bout dem fellas over yonder down by de riverbank, don’tcha think?”
• Why It Fails: It causes severe reading fatigue and can inadvertently lean into caricature or stereotype.

How to Fix It: Focus on Syntax, Word Choice, and Rhythm

Instead of altering spelling, convey regionality through sentence structure, idioms, and specific vocabulary choices. A few carefully placed regional words go much further than a wall of apostrophes.

• The Revision: “You lot ought to take a look at those guys down by the riverbank. They’ve been hanging around all morning.” (The use of you lot and hanging around instantly establishes a distinct British or colloquial voice without a single misspelled word).

6. Symmetrical Echoing

In poorly written dialogue, characters constantly repeat back parts of the questions they are asked. Conversations become perfectly balanced, predictable exchanges where Character A speaks, and Character B responds in direct alignment.

• The Mistake: “Are you going to the grocery store today?” “Yes, I am going to the grocery store today. Do you need anything?” “Yes, I need a carton of milk from the grocery store.” “Okay, I will get you a carton of milk.”
• Why It Fails: It is incredibly dull. Real conversation is messy, full of interruptions, non-sequiturs, and lateral jumps.

How to Fix It: Introduce Conversational Friction

Characters shouldn’t always answer questions directly. They might answer a question with a question, ignore it entirely, or respond to an unstated implication.

• The Revision: “Are you going to the store?” “We’re out of milk again, aren’t we?” “And bread. Don’t forget the receipt this time.”

7. Floating Disembodied Heads

This phenomenon occurs when a long string of dialogue takes place with zero physical context. The reader sees lines of text on the page, but the characters seem to exist in a blank white void, completely detached from their surroundings.

• The Mistake: Pages of back-and-forth talking with absolutely no mention of what the characters are doing, where they are standing, or how the environment is changing around them.
• Why It Fails: The emotional weight of the conversation is lost because the reader loses their visual anchor to the scene.

How to Fix It: Intertwine Dialogue with Micro-Actions

Ground the scene by letting your characters interact with their environment while they talk. Cooking dinner, driving a car, sorting mail, or pacing the room gives characters something to do with their hands, which in turn reveals their emotional state.

• The Revision: “I don’t think we should see each other anymore.” He paused, the knife hovering over the cutting board, a half-sliced tomato beneath the blade. He didn’t look at her, but his shoulders dropped an inch. “Is there someone else?” The knife came down, slicing clean through to the wood with a dull thud.

Dialogue Diagnostics Checklist

Before submitting a manuscript or publishing a chapter, print out your dialogue pages and run this quick diagnostic check:

1. Read it aloud: If your tongue trips over a sentence, or if you run out of breath, simplify the phrasing.
2. Highlight the tags: If your page is filled with colorful verbs (he grumbled, she snapped), change 80% of them to “said” or replace them with a physical action beat.
3. Check the balance: Ensure no single character is speaking in unchecked paragraphs of exposition unless they are delivering an intentional, dramatic speech.

By eliminating these rookie habits, your dialogue will transform from a clunky delivery system for plot points into an elegant, driving force that reveals character depth and keeps readers turning pages late into the night.
