How to write thoughts in a story comes down to two choices: how close the narration sits to the character, and how you mark direct thought. Italics are the most accepted marking, and quotation marks are also permitted in fiction.
Thought works best when it shares a voice with speech, so the advice on how to write slang in dialogue carries over directly to the inner voice.
How thoughts reach the page
Inner monologue is not one technique. It sits on a spectrum of closeness between narrator and character. Writer September C. Fawkes describes point of view penetration as a spectrum with four points, running from the most distant narration to the closest. Most stories move between levels rather than holding one throughout.
Two of those points matter most when you write thoughts:
- Direct thoughts (Point 3). The thought appears as the character’s own words, set apart from the narration. Writers commonly call this technique direct thoughts, and it follows the punctuation rules of dialogue, with italics where quotation marks would be.
- Prose that takes on the character (Point 4). At the deepest level, the narration adopts the thoughts and attitudes of the character, with no italics or tags. In effect, this is free indirect style: the narrator’s sentences carry the character’s judgements, so the reader hears the thought without being told it is a thought.
Choose by how much distance the moment needs. Direct thought gives the reader a clear, quotable line, which suits a decision or a sharp reaction. Deep, tag-free narration suits sustained interior stretches where repeated tags would feel mechanical.
Italics, quotation marks and tags
For fiction, the MLA Style Center says a writer may style a character’s thoughts in italics or in quotation marks. It adds that italics have the advantage of distinguishing thoughts from speech. Writer’s Digest goes further in its answer on styling a character’s thoughts, calling italics the most accepted way to handle a character’s internal thoughts.
MLA’s own fiction example pairs an italic thought with a tag: Julie thought to herself, Mother will be furious if she finds out I walked home instead of calling for a ride. The tag names the thinker and the italics mark where speech-like thought begins.
The practical result is that italics are the safer default. Quotation marks make a thought look identical to dialogue, so the reader has to rely on the tag alone to tell them apart. Choose quotation marks only if your publisher or the convention of your book asks for them, and then use them everywhere.
| Method | What it does | Planning use |
|---|---|---|
| Italics, usually with a tag | Separates thought from speech while keeping dialogue-style punctuation | Default for direct thought in most fiction |
| Quotation marks | Permitted in fiction, but thought looks like speech | Use only when house style or your book’s system requires it |
| No marking, narration takes on the character’s attitudes | Deepest level of closeness, with no italics or tags | Use for extended interior passages where tags would interrupt |
These options draw on the MLA Style Center’s guidance and on Fawkes’s description of the penetration spectrum.
Keeping point of view steady
Steady point of view means the reader always knows whose head they are in. In third person, Fawkes notes, narration is almost always told from one specific viewpoint character’s perspective per scene or chapter. If you give a thought to a character, the scene should belong to that character, and other people’s feelings should reach the reader only through what the viewpoint character can see, hear or guess.
Omniscient narration is the exception. There, the author can zoom in and out of any character’s head within paragraphs or sentences. That freedom is also the main risk: a thought that belongs to a different character, dropped in without a signal, reads as a mistake rather than a choice. If you move between minds, make each move clear in the sentence itself.
First person has its own convention. Fawkes reports that the writing world’s consensus is to avoid direct italic thoughts in first-person narration, though Fawkes considers that argument flawed. The reasoning behind the convention is that the narrator already speaks from inside the mind. If you do use italics in first person, keep them for a thought that sharply contrasts with what the narrator says aloud or does.
Because most stories mix levels, steadiness is about control rather than uniformity. Move closer or further away on purpose, at a scene break or a clear shift in tension, and not in the middle of a thought.
Making thoughts sound like the character
Character voice is what separates a thought that reveals someone from one that merely reports information. The deepest level of narration takes on the character’s thoughts and attitudes, which means diction, rhythm and bias should come through in the narration itself. A character who speaks in slang in dialogue should not turn formal the moment the quote marks disappear.
Use these checks to keep the inner voice consistent with the spoken one:
- Vocabulary. Let the same word choices that appear in a character’s speech appear in their thoughts, though privately a character may be blunter or less polished than aloud.
- Rhythm. Short, clipped thoughts suit a snap judgement. Longer, winding sentences suit rumination.
- Attitude. Let thought carry opinions the character would never voice, because that gap between what is thought and what is said is where inner monologue earns its place.
A useful exercise is to practise voice in a small, rhythmic form before returning to prose. Guides like How To Write A Limerick Poem: A Friendly 2026 Guide To Crafting Quick, Funny Verses – Slanguagestudio show how tightly wording and rhythm shape personality, and the same attention to word choice applies to a character’s private thoughts.
Drafting and revising thoughts
Treat thoughts as a decision you make scene by scene, not a layer you sprinkle on at the end. Follow these steps for each scene that needs interior voice:
- Set the closeness. Decide whether the scene stays at a distance or takes on the character’s attitudes, and note it when you plan.

- Pick one marking system. Use italics for direct thought unless house style says otherwise, and apply them the same way throughout.
- Write the thought in the character’s diction. Draft it in their words, then compare it with their dialogue to check they sound like the same person.
- Cut thoughts that only repeat the action. Keep a thought if it adds motive, feeling or an attitude the reader could not otherwise see.
- Check the viewpoint. Read the scene once for whose mind each thought belongs to, and fix any slip.
When a scene needs speed, favour short thoughts or action, and save longer interior passages for moments where the reader needs to understand a choice.
Frequently asked questions
What if I am writing by hand and cannot use italics?
Underline the thought instead, as Fawkes advises in her guide to writing thoughts. The underline stands in for italics and can be converted when the manuscript is typed.
Whose preference wins, mine or the publisher’s?
MLA says an editor should follow the house style guide when styling characters’ thoughts. If house style allows either approach, an author’s preference for italics or quotation marks can be followed, as the MLA Style Center explains.
How do I quote a character’s thoughts from another text?
If the source shows the thoughts in italics, MLA says to reproduce the italics and also enclose them in quotation marks. That keeps both the original styling and the signal that the words are quoted.
Are italic thoughts allowed in first-person narration?
They are allowed, but common advice discourages them, since the narrator already speaks from inside the mind. Fawkes disputes that reasoning, so use italics in first person only when a thought needs to stand out from the narration.
