Le Préfixe Re-: répétition

The re- prefix is the single most productive word-formation tool in French. Native speakers attach it to verbs on the fly, often creating forms that are not in the dictionary but are immediately understandable. Once you internalize the system, you stop learning refaire, redire, relire, revoir, recommencer as separate words — you learn the rule, and the words generate themselves.

This page covers the prefix's three spelling forms, its two distinct senses (again / back), and the full list of high-frequency re- verbs you will meet constantly in spoken and written French.

The three spellings: re-, ré-, r-

The form of the prefix depends on what sound it attaches to. The rules are phonological — they exist to keep the prefix easy to pronounce.

Re- before a consonant (default)

This is the most common form. The prefix is re- whenever the underlying verb begins with a consonant.

Ré- before a vowel (with the accent)

When the base verb begins with a vowel, the prefix usually takes the form ré- with an acute accent. The accent preserves the closed /e/ sound; without it, re- + vowel would create awkward pronunciations.

R- in well-established forms

A small set of high-frequency verbs uses the contracted form r- directly attached to the vowel-initial stem. These are historical formations that resisted the ré- pattern; native speakers learn them as fixed lexical items.

The two senses of re-: again vs back

A subtle but central feature of the prefix: it carries two related but distinct meanings, and most verbs admit both readings.

Sense 1: repetition (again)

The action is performed a second (or third, or nth) time. This is the dominant reading for re- verbs based on activity verbs that have no natural "return" sense.

Sense 2: return (back)

The action restores a previous state or location. This is the dominant reading for re- verbs based on motion verbs (revenir, retourner, rentrer) or state-change verbs (rouvrir, refermer).

Verbs that allow both

Many verbs sit at the intersection and admit either reading depending on context. The hearer disambiguates from the situation.

Productivity: making new re- verbs on the fly

The re- prefix is "productive," which means native speakers create new forms with it whenever they need to. Many of these forms are not in dictionaries but are perfectly natural in speech and writing.

For learners, this means two things. First, when you need to say "do X again" in French and you do not know if a re- form exists, try it. Repenser, redécorer, reconfigurer, renégocier, reformuler — they all exist and are widely used. The risk of making up a form that turns out not to exist is low; you will either be understood or gently corrected. Second, do not memorize every re- verb as a separate entry — recognize the productive process and parse on the fly.

Conjugation: follow the base verb

A re- verb conjugates exactly like its base. The prefix is invisible to morphology.

• Refaire conjugates like faire: je refais, tu refais, il refait, nous refaisons, vous refaites, ils refont.
• Reprendre conjugates like prendre: je reprends, tu reprends, il reprend, nous reprenons, vous reprenez, ils reprennent.
• Revenir conjugates like venir: je reviens, tu reviens, il revient, nous revenons, vous revenez, ils reviennent.
• Réécrire conjugates like écrire: je réécris, tu réécris, il réécrit, nous réécrivons, vous réécrivez, ils réécrivent.

Auxiliary choice in compound tenses also follows the base. Revenir, repartir, retomber, rentrer, remonter, redescendre, ressortir take être (they are based on motion verbs from the maison d'être). Refaire, redire, relire, réécrire, reprendre, retrouver take avoir. Whatever the base verb does, the re- verb does too.

Re- vs à nouveau / de nouveau

French has periphrastic ways of saying "again" — à nouveau and de nouveau — that compete with the re- prefix. The choice is largely stylistic, but there are tendencies.

• The re- prefix is more compact. It expresses repetition in a single word, often without further marking. Je relis is more economical than je lis à nouveau.
• À nouveau / de nouveau are more emphatic. They put the focus on the repetition itself. Je l'ai lu de nouveau draws attention to the fact that this is a second reading.
• Some verbs prefer one or the other. Recommencer feels complete on its own; commencer de nouveau is redundant. Conversely, periphrastic à nouveau combines easily with verbs that do not take a productive re- (expliquer à nouveau rather than réexpliquer, though both exist).
• Both can co-occur for emphasis: recommencer à nouveau (start over yet again).

Source-language note: English re- vs French re-

English and French both inherited the Latin re- prefix, and many re- verbs map directly between the two languages: rewrite/réécrire, redo/refaire, reread/relire, recommence/recommencer, reopen/rouvrir, reorganize/réorganiser. The semantic field overlaps almost entirely.

The main differences:

• Productivity is higher in French. Where English often prefers a periphrasis (do over, see again), French reaches for the re- verb (refaire, revoir). English speakers underuse re- when speaking French because they instinctively reach for the periphrasis they would use in English.
• The "back" reading is more developed in French. English re- almost exclusively means "again" (rewrite, return being a Latin borrowing). French re- commonly means "back": revenir (come back), rapporter (bring back), remettre (put back), retourner (return).
• Spelling alternation has no parallel in English. English re- never contracts; French shifts among re-, ré-, and r- based on what follows.

Common Mistakes

Mistake 1: Spelling réécrire as reécrire.

Mistake 2: Forgetting to use re- and reaching for periphrasis instead.

Mistake 3: Inventing re- forms for irregular alternations.

Mistake 4: Confusing rappeler (call back / remind) with appeler (call).

Mistake 5: Using a wrong auxiliary in the compound tense.

Mistake 6: Confusing redire (say again) with retraduire (translate back) or other approximate forms.

Key takeaways

• The re- prefix is highly productive — it attaches to most verbs and creates an immediately understandable new form meaning "do again" or "do back."
• Spelling: re- before a consonant, ré- before a vowel (with the accent), r- in established contractions (rouvrir, rappeler, rallumer).
• Two senses: repetition (refaire, relire) and return (revenir, remettre). Many verbs admit both; context disambiguates.
• Conjugation follows the base verb exactly — including auxiliary choice in compound tenses. Revenir takes être because venir does; refaire takes avoir because faire does.
• Productivity: try out re- forms when you need them. Most exist; the few that do not will be cheerfully corrected by your interlocutor.
• Compact re- beats periphrastic "à nouveau" in casual speech for most simple repetitions. Reach for réécouter, réessayer, redire instead of écouter à nouveau, essayer encore une fois, dire de nouveau.
