Repetition: when to avoid it and when to use it

At school we learned that repetition is a mistake: the same word twice in a sentence must be replaced with a synonym. It's good advice for an essay, less so for a novel. In fiction some repetitions really are flaws, while others are among the most effective tools for giving a page rhythm and force. The work lies in telling them apart.

Accidental repetition

It comes from inattention: the same word returns a few lines later for no reason.

He opened the door and looked outside. Outside there was a strange silence. He looked towards the road.

Readers don't register it as an effect; they perceive it as carelessness. Even when they don't consciously notice, they feel the prose is less fluid.

The most frequent ones involve generic verbs (do, go, look, seem), time adverbs (then, suddenly) and pet words, the ones every writer tends to use without realising.

Intentional repetition

This is the kind readers perceive as deliberate, and which creates an effect:

She waited an hour. She waited two hours. She waited until the light changed colour.

Here repetition makes us feel time passing better than any description. Other uses:

• emphasis: repeating a key word to press it home;
• rhythm: building a cadence, almost musical;
• echo: recalling a sentence or image chapters later to link two moments;
• voice: a character who always repeats the same expressions is characterised by them.

The test: effect or slip

The question is simple: does the reader notice it as an effect or as a distraction? Intentional repetition is usually conspicuous, constructed, placed at a precise point. The accidental kind is random, scattered, and adds nothing.

The synonym trap

The school remedy, replacing with a synonym, often creates a worse problem. If a character is "Mark", then "the boy", then "the young man", then "the blond", readers wonder whether these are different people. Dialogue tags are the best-known example: said, replied, retorted, pronounced, declared stand out far more than a repeated said.

Some words are almost invisible and can be repeated freely: character names, said, articles and prepositions. Readers don't perceive them as repetition.

How to fix it

Instead of reaching for a synonym, first try to:

• rephrase the sentence so the word is no longer needed;
• cut: the second occurrence was often superfluous;
• use a pronoun, if it doesn't create ambiguity;
• change the construction, merging two sentences into one.

Only if none of these works, look for a synonym, as long as it's exact and natural.

How to find them

Accidental repetitions slip through while drafting, because writers follow meaning rather than words. They're easier to spot when reading aloud, or when rereading in a different format. A checker that flags words repeated close together helps find them, but deciding whether to keep them is still up to you.

Frequently asked questions

At what distance does repetition become a problem?

There's no fixed measure. It depends on the word: a rare or very distinctive term stands out even a page apart; a common word only in the same or the next sentence.

Should repetition in dialogue be corrected?

Less than in narration. Real people repeat themselves when they talk, and overly polished dialogue sounds fake. What matters is that the repetition fits the character and the moment.

Can I repeat whole sentences at a distance?

Yes, and it's an effective technique: a sentence returning at a key moment takes the reader back to the beginning and creates a sense of closure. It works when used once or twice, not as a habit.
