Demander des Précisions

Asking for clarification — when you didn't catch something, didn't understand a word, or just need the speaker to slow down — is one of the highest-value skills for any learner. It is also a politeness minefield. The difference between Pardon ? (polite, neutral) and Quoi ? (informal, can sound rude) is the difference between asking gracefully and accidentally insulting someone. This page covers the everyday repertoire: how to signal that you didn't hear, that you didn't understand, that you need a word explained, that you want the speaker to slow down — and how to upgrade any of those moves to formal register when you're talking to a stranger, a superior, or a service worker.

The good news for English speakers: most French clarification phrases have direct functional equivalents in English. The traps are mostly social — knowing which form fits which situation.

Pardon ? and Comment ? — the basic "what was that?"

The two everyday "I didn't catch that" responses are Pardon ? and Comment ? They are not interchangeable in tone.

Pardon ? — literally "pardon?" — is the polite, all-purpose request for repetition. It works in any register: with friends, with strangers, in shops, at work. It comes with a built-in apology, which is why it's so universally safe.

Comment ? — literally "how?" — is also widely used and not impolite, but it's a touch more abrupt. It's the bare "what?" with no apology attached. Many speakers prefer Pardon ? in formal contexts and reserve Comment ? for among friends.

A trap: Quoi ? — "what?" — is (informal) and can sound brusque or even rude with strangers. Used among close friends it's fine, but in service contexts or with people you don't know, it sounds like you're snapping. Pardon ? is the safe default.

Excusez-moi — the polite opener

When you want to interrupt politely to clarify something, excusez-moi (formal) or excuse-moi (informal) is the standard opener. It signals "I'm about to ask something — I know I'm interrupting."

In service contexts — shops, hotels, trains — excusez-moi, madame/monsieur is the standard polite opener for any clarification request. It positions you as someone who knows the social code and signals respect.

Asking for repetition

The full polite request for repetition uses the verb répéter — almost always with pouvoir in conditional or present:

The conditional pourriez-vous is more polite than the present pouvez-vous. In service or formal contexts, the conditional is the default. With friends and family, the present is fine.

A useful variant uses redire (to say again) instead of répéter:

Redire (re- + dire) is slightly less formal than répéter and feels more conversational.

Asking the speaker to slow down

When the issue isn't volume but speed — a French speaker is firing words faster than you can process — the standard request is parler plus lentement.

A useful framing: J'apprends le français (I'm learning French) tells the speaker exactly what to adjust. French speakers are generally happy to slow down once they know the situation — what feels confusing is being asked to repeat the same fast utterance several times when slowing down would solve it.

A polished alternative is un peu plus lentement — adding un peu takes the edge off the request:

Asking what something means

When the problem is a specific word or expression, the go-to phrase is Qu'est-ce que ça veut dire ? — literally "what does that want to say?"

The verb vouloir dire (literally "to want to say") is the standard way to ask about meaning. The English equivalent is to mean, but French does not have a single verb for mean in this sense — vouloir dire is the lexicalised expression.

A more formal variant is Que signifie X ?

In school, in lectures, in formal writing — signifier and vouloir dire are both used. In conversation, vouloir dire dominates.

Asking how something is spelled or written

For spelling, French uses s'écrire (to be written / to spell oneself).

The reflexive s'écrire in Comment ça s'écrit ? is the everyday phrasing — literally "how does it write itself?" The verb épeler (to spell, letter by letter) is more specific and is what you ask for when you want the spelling letter by letter.

Asking for an explanation

When clarification is needed at the level of meaning rather than vocabulary — a concept, an idea, a decision — the verb is expliquer.

The verb reformuler (to rephrase, reword) is a polished way to ask for a different formulation rather than the same one repeated. It's especially useful when the original phrasing wasn't the issue — you understood the words but didn't follow the meaning.

Buying time — une seconde, attendez

Sometimes you don't need new information yet — you just need a moment to process what's been said.

These holding phrases buy you the seconds you need without forcing the speaker to repeat. They're especially useful on the phone or when you're processing something complicated.

Saying you didn't understand

Two phrasings for the basic admission:

A useful distinction: je n'ai pas compris (I didn't understand) vs je n'ai pas bien entendu (I didn't hear well). The first is about meaning; the second is about audibility. Specifying which is the issue helps the speaker know whether to repeat louder, repeat slower, or rephrase.

The verb saisir (to grasp) is a slightly more polished alternative: je n'ai pas saisi (I didn't catch) — common in professional or careful speech.

In conversational French, the ne of ne… pas is often dropped: j'ai pas compris, j'ai pas bien entendu — the famous spoken-French ne-deletion. Both forms are heard; the dropped ne is (informal) but completely standard in everyday speech.

Confirming understanding — si je comprends bien

A more sophisticated clarification move is to summarise your understanding back to the speaker for confirmation. This serves both as a check and as a sign of attentive listening.

The structure si je comprends bien, … (if I understand correctly, …) is a polished, professional clarification frame. It signals that you've been listening and want to confirm before moving on. Vous voulez dire que… ? (you mean that…?) does similar work, focused more on the speaker's intent than your interpretation.

The phrase autrement dit (in other words / put another way) is useful for restating something more simply.

Formal clarification frames

In formal contexts — meetings, customer service, official correspondence, talking to authorities — the politeness level rises. Standard frames:

The pattern pourriez-vous + infinitive is the standard formal request frame. Auriez-vous la gentillesse de (would you have the kindness to) is one notch up the formality scale and would suit a written letter or a very formal exchange.

The phrase je me permets de + infinitive is a useful frame for any potentially intrusive question or comment. It signals careful, deferential phrasing.

Service-context openers

In shops, ticket counters, restaurants, post offices, the standard polite-opener-for-clarification is Excusez-moi, monsieur/madame, …:

The opener Excusez-moi… + service title (monsieur, madame) does several things at once: it signals respect, it gets the worker's attention, and it positions the question as a polite request rather than a demand.

Common Mistakes

Quoi ? alone, addressed to a stranger or in any service context, sounds sharp. Pardon ? is the universally polite version.

The two patterns are alternatives, not combinations. Pick one: vouloir dire (everyday) or signifier (formal).

For "how is it spelled?", French uses s'écrire. Épeler exists, but it's used in the active form: vous pouvez épeler ?, vous pouvez l'épeler ?

A bare imperative request without s'il vous plaît and without softening (un peu) sounds peremptory in French. Frame the request and explain.

In pouvez-vous répéter, the second verb is in the infinitive (répéter), not the conjugated form. Two verbs in sequence — modal + main — give you modal-conjugated + main-infinitive. Also, with inversion, the hyphen is required: pouvez-vous.

For asking the meaning of a word or phrase, the standard subject is ça (impersonal). Using il/elle personifies the word in a way that sounds odd.

When you want to check that your listener has followed, je suis clair ? (am I clear?) or je me fais comprendre ? (am I making myself understood?) puts the burden on you, not on them. Vous comprenez ? can imply doubt about the listener's capacity.

Key takeaways

• Pardon ? is the safe, polite "sorry?" in any context. Comment ? is fine but slightly more abrupt. Quoi ? is informal-only and can sound rude.
• Excusez-moi is the polite-opener for any clarification request. In shops and service contexts, pair it with monsieur / madame.
• For the meaning of a word: qu'est-ce que ça veut dire ? (everyday) or que signifie X ? (formal).
• For spelling: comment ça s'écrit ? — or vous pouvez l'épeler ?
• For slowing down: vous pouvez parler un peu plus lentement, s'il vous plaît ? — and explaining why (j'apprends le français) helps enormously.
• The summarise-and-confirm move — si je comprends bien, … / vous voulez dire que… ? / autrement dit, … — is the most professional way to verify your understanding.
• Formal frames: pourriez-vous m'expliquer … / auriez-vous la gentillesse de … / je me permets de …
• The conditional softens. Use pourriez-vous over pouvez-vous when in doubt.
