Free indirect discourse
Free indirect discourse is a third-person narration technique in which the narrator's voice takes on the vocabulary, judgements and rhythms of a character's thoughts, without quotation marks and without a tag such as 'she thought.'
Compare three versions of the same moment:
- Direct thought: She thought, "He is insufferable."
- Reported thought: She thought that he was insufferable.
- Free indirect: Honestly, the man was insufferable.
The third sentence stays in third person and past tense, but the opinion, the honestly, and the slightly prim the man all belong to the character. The narrator has stopped reporting her mind and started speaking in it.
Jane Austen is usually credited with making the technique standard in English, and Flaubert with pushing it furthest; it is now the default voice of most close third-person fiction. What it buys you is the intimacy of first person while keeping third person's freedom to pull back for a wider view.
It is also frequently the fix for a draft that feels oddly distant. Prose can be clean and still hold the reader at arm's length because every perception is reported rather than inhabited. Cutting filter words often converts reported thought into free indirect discourse on its own.
The risk is at the boundaries. When two characters' voices bleed into the narration inside one scene, free indirect discourse becomes head-hopping.
