TL;DR: An interior monologue is a character's unspoken thoughts written in their own voice. To write one that holds a reader: anchor it to a decision the character is about to make, use their syntax instead of yours, ground it in the body, and get back to the scene fast. Boring interior monologue is rarely too long. It's untethered from action.
You've already written interior monologue. Every author has. The problem is that most of it does the opposite of what it's supposed to do.
The intent is characterization. The result is a character standing still, narrating feelings the reader already inferred 2 paragraphs ago. Editors call it navel-gazing, and it's one of the most common reasons a promising manuscript gets a rewrite note.
The fix isn't cutting interior monologue. It's making every line of it earn its place. Here's how to write an interior monologue that reveals motive, raises tension, and keeps the scene moving.

What is an interior monologue?
An interior monologue is a passage of a character's unspoken thoughts, written in their voice, revealing motive, conflict, or a decision as it forms.
It happens inside the character's head, not out loud. That's the whole distinction from a stage or screen monologue. Nobody hears it. Nobody responds to it.
Interior monologue shows up in 3 forms, and most published fiction mixes all 3:
- Direct interior monologue. First person, present tense, the thought exactly as thought. I can't tell her. Not tonight.
- Indirect interior monologue. The thought filtered through the narrator's voice, usually third person past tense. She couldn't tell her. Not tonight.
- Free indirect discourse. Narrator voice and character voice fused, with no thought tag and no italics. The most flexible of the 3, and the one strong fiction leans on hardest.
Interior monologue vs. internal monologue vs. stream of consciousness vs. soliloquy
These 4 terms get used interchangeably, and the confusion costs authors clarity in revision. Here's the working distinction:
| Term | Where it happens | Structure | Use it when |
|---|---|---|---|
| Interior monologue | Inside the character's mind | Shaped, ordered, readable | You want motive or a decision on the page |
| Internal monologue | Inside the character's mind | Same thing, different label | Treat the 2 terms as synonyms |
| Stream of consciousness | Inside the character's mind | Unfiltered, associative, often ungrammatical | The disorder of the thinking is the point |
| Soliloquy | Spoken aloud, alone on stage | Formal, performed, audience-facing | You're writing drama, not prose fiction |
The one that trips up most authors: stream of consciousness is a technique for rendering interior monologue, not a separate thing. All stream of consciousness is interior monologue. Very little interior monologue is stream of consciousness.
Interior monologue example: one moment, written 3 ways
A strong interior monologue example shows a decision forming in the character's own syntax. A weak one summarizes an emotion the scene already delivered.
Same beat in all 3 versions: Nadia is standing outside her sister's apartment with an envelope she hasn't decided whether to hand over.
Version 1 · Telling
Nadia felt nervous and conflicted as she stood at the door. She was worried about how her sister would react to the news, and she wondered whether telling her was the right decision. She had never felt so uncertain in her life.
Nothing here is thought. It's a report about thought, written in the author's voice. The reader learns Nadia is conflicted, which they'd already worked out from the fact that she's standing outside a door holding an envelope.
Version 2 · Indirect, better
She could still leave. Slide it under the door, drive home, let Mara find it at 6 a.m. with her coffee and no one watching her face. That was the coward's version. It was also the version where Mara never had to perform anything for anyone.
Now the reader is inside a real argument. Two options, one bias, a rationalization already forming. This is indirect interior monologue: third person, past tense, but the vocabulary and the self-judgment belong to Nadia.
Version 3 · Grounded and decisive
The envelope had gone soft at the corner where her thumb kept working it. Slide it under. Drive home. Let Mara read it at 6 a.m. with nobody watching her face.
Coward, she thought, and knocked anyway.
Same content, half the words, and it ends in action. The body detail (a thumb worrying a paper corner) anchors the thinking in the physical scene, and the monologue resolves into a decision instead of dissolving into more reflection.
What changed across the 3 versions
- Emotion labels ("nervous," "conflicted," "uncertain") got cut and replaced with the thinking that produces them.
- The syntax got shorter and more clipped, which is how a person actually thinks under pressure.
- The passage ends on a choice, so the scene moves forward instead of pausing.
That's the core of show, don't tell applied to thought rather than action.
How to write an interior monologue in 6 steps
Anchor the monologue to a decision, write it in the character's syntax, cut what the scene already shows, ground it in the body, and return to action.
1. Anchor every interior monologue to a decision
The strongest interior monologue sits directly before a choice. The character is about to do something irreversible, and the monologue is them talking themselves into it or out of it.
That's why it holds attention. The reader isn't watching someone feel. They're watching someone decide, which means there's an outcome pending.
If you have a passage of interior monologue with no decision attached to it, you have 2 options: attach one, or cut it.
2. Write in the character's syntax, not yours
Voice isn't only vocabulary. It's sentence length, rhythm, and what the character notices first.
Ask 3 questions before you write a character's thoughts:
- Do they think in complete sentences or fragments?
- Do they reason toward a conclusion, or arrive at one and justify it backward?
- What do they refuse to think about directly?
That third question does more work than the other 2 combined. What a character avoids thinking about becomes the payoff later in their arc, when they finally can't avoid it. Build this during character development, before you draft, so each viewpoint character's monologue sounds measurably different from the others.
3. Cut anything the scene already shows
This is the highest-yield edit in the whole list. If a character slams a door, you don't need a line of thought telling us they're angry.
Interior monologue should add information the reader can't get from the outside: the reason behind the action, the memory it triggered, or the thing the character is choosing not to say out loud. Anything else is duplication.
The duplication test
Delete the interior monologue passage and reread the scene. If nothing is lost, it was duplication. If the scene now feels flat or the motive is unclear, the passage was doing real work. Keep it.
4. Ground the thought in the body
Readers tolerate long interior passages when they still know where the character is standing. Lose the physical world and the prose starts floating.
Thread sensory detail through the thinking: a sound that interrupts it, an object the character is handling, the temperature of the room. In the Nadia example above, a single soft corner on an envelope does the whole job.
Strong, specific verbs help here too, since a vague verb in a thought reads as the author's summary rather than the character's perception. Our strong verbs list is a fast reference during revision.
5. Pick one formatting convention and keep it
Inconsistent thought formatting is one of the fastest ways to look unedited. Choose your approach in chapter 1 and apply it to the last page. Full rules are in the next section.
6. Ration interior monologue against action and dialogue
Interior monologue slows pace by design. That's a feature when you want the reader to sit with a moment and a problem when the plot needs to move.
2 practical checks during revision:
- The page test. Flip through your manuscript without reading it. Any page that's a solid block of prose with no dialogue and no white space is a pacing risk. Check whether it's monologue.
- The 2-page rule. If a character has been thinking for more than 2 pages without speaking, moving, or being interrupted, you're asking a lot of the reader. Break it with dialogue or an event.
The reverse is also true. If you've written 4 pages of fast cutting and want to decelerate before a turning point, interior monologue is the cleanest way to do it. See our guide to pacing in writing for how these levers work together.
Struggling to make your characters sound like different people?
Voice is the hardest part of fiction to self-diagnose, because every character sounds right in your own head. Fundamentals of Fiction walks you through character voice, scene structure, and pacing with feedback on your actual pages. See Fundamentals of Fiction
How to show inner monologue in writing
Show inner monologue with italics for direct thought, plain text for indirect thought, and no thought tags once the point of view is established.
There's no single correct convention, but there is a correct way to use one: consistently. Here are the 4 standard options and what each signals to a reader.
| Convention | Looks like | Best for | Watch out for |
|---|---|---|---|
| Italics, no tag | Not tonight. | Direct thought in third person | Fatigue if overused; italics lose punch |
| Italics + thought tag | Not tonight, she thought. | Establishing the convention early on | Redundant once POV is clear |
| Plain text, no tag | Not tonight. She knocked anyway. | Free indirect discourse and deep POV | Needs a tight POV or it reads as narration |
| Plain text + tag | She thought about telling her. | Summarizing thought at distance | Filter words push the reader out of the head |
3 formatting rules worth following
- Don't use quotation marks for thought. Quotation marks mean speech. Using them for thought confuses readers and flags an unedited manuscript.
- Drop thought tags once the convention lands. After a few chapters in a tight POV, "she thought" is a filter word. So are "she realized," "she wondered," and "she felt."
- Use italics sparingly in first person. If the narration is already the character's voice, italicizing thought creates a distinction the reader doesn't need.
For broader punctuation and formatting standards across your manuscript, see our guide to writing conventions.
Internal monologue writing techniques by point of view
Point of view determines how much interior access you have. Choose the POV first, then apply the internal monologue writing techniques that fit it.
| POV | Interior access | Technique that fits | Main risk |
|---|---|---|---|
| First person | Total, and constant | Narration is the monologue; italics only for sharp, present-tense thoughts | Endless reflection; the narrator explains instead of experiences |
| Third limited / deep POV | 1 character at a time | Free indirect discourse, minimal tags | Head-hopping between characters mid-scene |
| Third omniscient | All characters, at distance | Brief, tagged indirect thought | Reader never bonds deeply with anyone |
| Second person | Total, and disorienting by design | Direct address blurring thought and narration | Hard to sustain past short fiction |
If you're writing multiple viewpoint characters, run a diagnostic before you revise: copy 200 words of each character's interior monologue into one document, strip the names, and read them back to back. If you can't tell who's who, the voices aren't differentiated yet.
5 mistakes that make interior monologue boring
Most boring interior monologue fails for 1 of 5 reasons: no stakes, duplication, rhetorical question stacking, emotional repetition, or bad placement.
- Thinking with nothing at stake. Reflection with no pending decision is the literary equivalent of a character reading the newspaper. Attach a choice.
- Restating the scene. If the action already showed it, the thought shouldn't say it.
- Stacking rhetorical questions. "What was she going to do? How could this have happened? Why now?" One works. Three in a row reads as the author performing anxiety.
- Repeating the same emotion in new words. A character can only realize they're afraid once. After that, the fear has to change shape or escalate.
- Interrupting high-tension action. Nobody reflects at length mid-chase. Under real pressure, thought compresses into fragments. Save the paragraphs for before and after.
Interior monologue FAQ
What is an example of an interior monologue?
Any passage of unspoken thought in a character's voice. For example: "Slide it under the door. Drive home. Let her read it at 6 a.m. with nobody watching her face." It's thought rendered directly, in the character's rhythm, rather than summarized by the narrator.
What's the difference between interior monologue and stream of consciousness?
Interior monologue is the broad category: a character's thoughts on the page. Stream of consciousness is one technique inside it, where thought is rendered unfiltered and associative, often without standard grammar. Most interior monologue is shaped and orderly; stream of consciousness deliberately isn't.
Should interior monologue be in italics?
Only for direct, present-tense thought in third person narration. Indirect thought and free indirect discourse run in plain text. In first person, italics are usually unnecessary because the narration is already the character's voice. Pick one convention and hold it for the whole book.
How long should an interior monologue be?
Long enough to resolve into a decision, short enough that the reader still knows where the character is standing. As a working limit, if a character has been thinking for more than 2 pages without speaking, moving, or being interrupted, break it up.
Can you write interior monologue in third person?
Yes, and most commercial fiction does. Third limited POV supports free indirect discourse, where the narrator's voice and the character's voice merge without italics or thought tags. It gives you interior access without the constraints of first person.
Does every character need an interior monologue?
No. Only viewpoint characters get interior access. Giving thoughts to a non-POV character in the same scene is head-hopping, and it's one of the most common POV errors in first novels.
Your next step
Interior monologue is a revision skill more than a drafting skill. Write the thoughts messy in your first draft, then run the duplication test, the page test, and the voice diagnostic on every passage.
Most authors who struggle with this aren't short on talent. They're short on feedback, because you can't hear your own characters' voices from the inside. That's what coaching solves.
