Mistake: Dialogue That's Too Formal or Grammatically Perfect

Real conversation is full of sentence fragments, interruptions, and imperfect grammar. Dialogue that reads like a formal essay often feels stiff and unnatural. Letting characters speak in fragments, especially during emotional or fast-paced scenes, usually sounds more authentic.

Mistake: Every Character Sounds the Same

If you covered up character names, could you tell who's speaking based on word choice and rhythm alone? Distinct dialogue often comes from small, consistent choices, one character who never uses contractions, another who trails off mid-thought, another who asks questions instead of making statements.

Mistake: Over-Explaining Through Dialogue

Having characters explain information purely for the reader's benefit, information both characters would already know, is a common giveaway of unnatural dialogue. This is sometimes called "As you know, Bob" dialogue, and it tends to pull readers out of the scene.

Mistake: Too Many Dialogue Tags and Adverbs

"He said angrily," "she asked curiously," and similar tag-plus-adverb combinations often tell the reader how to feel rather than showing it through the dialogue itself. Strong dialogue frequently doesn't need adverbs at all, since word choice and context should convey tone on their own.

Fix: Read Dialogue Out Loud

Reading dialogue aloud, or having someone else read it, quickly reveals lines that sound unnatural on the page but obviously stilted when spoken. This is one of the simplest and most effective editing techniques for dialogue specifically.

Fix: Use Subtext Instead of Direct Statements

In real conversation, people rarely say exactly what they mean, especially in tense or emotional situations. Dialogue that hints at an underlying feeling without stating it directly often feels more realistic and engaging than dialogue that's completely on the nose.

Fix: Vary Sentence Length and Rhythm

Dialogue made up entirely of similar-length sentences can start to feel monotonous. Mixing short, clipped exchanges with occasional longer statements creates more natural rhythm, similar to how real conversations actually flow.

Final Thoughts

Strong dialogue takes practice and usually multiple revision passes to get right, even for experienced writers. It's one of the areas where outside feedback tends to be especially valuable, since writers are often too close to their own characters' voices to notice repetition or stiffness. This is a common focus area during the line editing stage that teams like Author's Dream work through with authors, refining not just grammar but how natural and distinct each character's voice actually sounds on the page.
