Three Ways to Format Internal Monologue (and Why Two Are Wrong)

Your protagonist is thinking. How do you show it?

Three approaches exist, and most manuscripts mix them up without knowing the trade-offs.

Quotation marks: “I can’t believe she said that.” The old-school method. Readers confuse thoughts with spoken dialogue, so you add “she thought” tags to disambiguate. Belt and suspenders. It slows prose down.

Italics work cleaner. Readers know it’s internal. But italics accumulate fast. A page full of slanted text gets visually noisy, and the formatting announces “this is interiority” instead of just living inside the character’s head.

Unmarked inline: She couldn’t believe she’d said that. No formatting. The narrator’s voice and the character’s thought merge into one stream. This is deep POV, and it’s where most contemporary fiction lives.

Most published novels today use unmarked inline for 80% of interiority, italics for short emphasis, and quotation marks almost never. Pick one primary method before drafting. Consistency matters more than which one you choose.

Find every italicized thought in your current chapter. Rewrite each one as unmarked narration. Read both versions aloud. Whichever disappears into the prose, where you stop noticing formatting and start feeling the character, is your default.
