L'Aspect Itératif: re- préfixe et réitération

Repetition is a fundamental feature of how we describe action. We do things again, we keep doing them, we do them over and over, we do them every day. English handles this with a small toolkit — the prefix re-, adverbs like again, the auxiliary keep, modals like would for habitual past — and so does French, but with a different distribution of work. The French system pivots on the highly productive re- prefix, a set of iterative periphrastics, and the central role of the imparfait in marking habitual past. This page lays out the full machinery.

By the end, you should be able to choose between refaire and faire à nouveau, between passer son temps à and ne pas arrêter de, between an imparfait of habit and a passé composé with trois fois. These are the choices that mark the difference between basic French and natural-sounding French.

The productive re- prefix

French re- (sometimes shortened to r- or ré-) attaches to verb stems to derive a new verb meaning "do again" or "do back." The prefix is productive: native speakers create new re- verbs on the fly, and the resulting forms are immediately understandable.

The conjugation of a re- verb follows the conjugation of the underlying verb exactly. Refaire conjugates like faire, redire like dire, revoir like voir, recommencer like commencer (with the ç before a/o).

The two meanings of re-: again vs back

A subtle point: French re- carries two related but distinct meanings.

1. Again (repetition): refaire = do over, redire = say again, relire = reread. The action is performed a second time.
2. Back (return to previous state or location): revenir = come back, retourner = return, rouvrir = reopen.

Some verbs straddle both — reprendre can mean "take again" (repetition) or "take back" (recovery), depending on context.

Spelling: re-, ré-, or r-?

The prefix has three forms depending on the verb stem.

• re- before consonants: refaire, redire, revoir, reprendre.
• ré- before vowels (and sometimes for emphasis): réécrire, réagir, réessayer. The accent on é preserves the closed /e/ sound.
• r- when the underlying verb begins with a vowel and the resulting form is well-established: rouvrir (from ouvrir), rappeler (from appeler), rallumer (from allumer), rapporter (from apporter).

The choice between ré- and r- before vowel-initial stems is partly historical, partly phonological. Réécrire (with the accent and double e) is now considered the standard form, though récrire still exists in some texts.

Periphrastic iteration: ne pas arrêter de and friends

For repeated or continuous action — "he doesn't stop talking," "she keeps complaining," "they spend their time arguing" — French uses periphrastic constructions built on auxiliary verbs.

Ne pas arrêter de + infinitive

The most common emphatic-iteration construction. Literally "not to stop V-ing," it conveys that the action is happening incessantly.

In casual speech, the ne often drops: il arrête pas de parler. The construction works in any tense — il n'arrêtait pas de parler, il n'a pas arrêté de parler, il n'arrêtera pas de parler — though the present and passé composé are by far the most frequent.

Passer son temps à + infinitive

This phrase paints the action as occupying the subject's time, often with mild reproach or weary resignation.

The possessive adjusts to the subject — je passe *mon temps à, tu passes **ton temps à, il passe **son temps à, nous passons **notre temps à, vous passez **votre temps à, ils passent **leur temps à*.

Continuer à / continuer de + infinitive

For "to keep on V-ing" without the emphatic note of ne pas arrêter de, French uses continuer à (or, equivalently for many speakers, continuer de) + infinitive. This is the neutral way to express persistent action.

The choice between continuer à and continuer de is essentially free in modern French; continuer à is slightly more frequent in speech, continuer de slightly more frequent in writing.

Faire et refaire

A vivid stylistic doubling: pairing the simple verb with its re- counterpart to emphasize repeated, often pointless, redoing.

This pattern is more emphatic than the simple re- verb alone: il fait et refait highlights an obsessive cycle.

Encore et encore — over and over

The adverb encore by itself means "again" in the simple sense:

Doubled — encore et encore — it intensifies into "over and over":

The doubled form is reserved for genuine emphatic iteration; for ordinary repetition, simple encore or à nouveau is enough.

À nouveau / de nouveau — "again"

These two adverbs both mean "again," and they're often interchangeable, with a slight semantic distinction that's worth knowing.

• De nouveau = once more (a second occurrence of the same action, often with no change).
• À nouveau = anew (a fresh start, often implying a change in conditions).

In practice, the distinction is loose, and many speakers use them interchangeably.

The choice between re- prefix and à nouveau / de nouveau is often stylistic. Refaire le ménage and faire le ménage à nouveau both work; the re- version is more compact, the periphrastic more emphatic.

Toujours + verb — habitual reading

Toujours means "always" or "still," depending on context. With present-tense verbs, it often signals habit — a recurring or characteristic action.

This is closely related to the imparfait-of-habit, which we'll cover next.

The imparfait: the central marker of past habit

For habitual or repeated action in the past, French uses the imparfait — not the passé composé. The imparfait of habit describes recurring or customary action over an extended past period.

The English translation of habitual imparfait often uses "would" or "used to" — we would go to the sea every summer, I used to work weekends. These English forms are imperfect equivalents; the French imparfait is the unmarked default for past habit, while English "would" and "used to" are slightly emphatic.

The imparfait pairs naturally with iterative time expressions: tous les jours (every day), chaque matin (each morning), toutes les semaines (every week), à chaque fois (every time), régulièrement (regularly).

See Imparfait: habitual past for the complete treatment.

Habit vs single event

A famous contrast that rests entirely on aspect choice:

The lexical content is the same (aller à la mer); the aspectual reading is entirely encoded in the choice between imparfait (habit, recurring) and passé composé (single event, bounded).

Chaque fois que… — every time that…

The conjunction chaque fois que introduces a clause expressing habitual conjunction — "every time X happens, Y happens." Both clauses typically take the same tense.

The variant à chaque fois que is also widespread in modern French and means the same thing.

Punctual repetition: number + fois

For counted or punctual repetition — "three times," "twice," "twenty-seven times" — French uses nombre + fois. This combines naturally with the passé composé (each repetition is a bounded event).

The phrase une fois is pronounced with the s silent (/yn fwa/), as is the standard pattern for fois.

For "once" (one time), une fois alone, often paired with adverbs of time:

For "twice" (two times), deux fois; for "three times," trois fois; and so on. There is no specialized word for "twice" — French simply counts.

Source-language note: English vs French repetition

English distributes the work of expressing repetition across several different mechanisms: the prefix re-, the adverb again, the auxiliary keep + V-ing, the construction would for past habit, and a separate vocabulary item used to. French does much of this work with two key tools: the re- prefix (more productive than English's), and the imparfait of habit (which absorbs both used to and habitual would).

The re- productivity is one of the more striking features of French verb morphology. Where English speakers might say "I'll watch the film again" or "I'll rewatch the film," French has revoir sitting ready as a single lexical item. Native speakers almost always reach for it.

The imparfait of habit is the bigger hurdle. English speakers tend to translate "I used to live in Paris" as j'utilisais d'habiter à Paris or some other word-for-word horror; the right French is j'habitais à Paris. The imparfait alone, without any auxiliary or marker, encodes the habitual reading. Once you internalize this, your French past tense narration becomes radically more natural.

Common Mistakes

Mistake 1: Using passé composé for habitual past actions.

Mistake 2: Using re- incorrectly with vowel-initial stems (forgetting the spelling shift).

Mistake 3: Trying to translate "used to" with a separate auxiliary.

Mistake 4: Doubling encore unnecessarily.

Mistake 5: Using passer son temps without the possessive adjective.

Mistake 6: Confusing encore (still / again) with toujours (always / still).

Key takeaways

• The re- prefix is highly productive: it attaches to most verbs to mean "do again" or "do back." Spelling shifts to ré- before vowels and to r- in established forms (rouvrir, rappeler).
• The two senses of re- are repetition (refaire, redire) and return (revenir, retourner). Most verbs accept both readings; context disambiguates.
• Periphrastic iteration: ne pas arrêter de (be incessantly V-ing), passer son temps à (spend one's time V-ing), and stylistic X et reX (do and redo).
• Habitual past is the imparfait's territory. English "used to," "would," and "every X" all map to the imparfait without auxiliary. Tous les étés on allait à la mer.
• Counted repetition uses nombre + fois with the passé composé: je l'ai dit trois fois (I said it three times).
• À nouveau and de nouveau both mean "again," with a soft distinction (à nouveau = anew/fresh start; de nouveau = once more). In practice, often interchangeable.
• Chaque fois que, à chaque fois que, and toutes les fois que introduce habitual-conjunction clauses, with both clauses normally in the same tense.
