French has more markers for contrast than for almost any other discourse function — and the choice between them is one of the clearest register signals in the language. Drop par contre into a formal report and an editor will cross it out. Use or in casual chat and you sound like a 19th-century novelist. Misuse pourtant for par contre and your sentence stops making sense altogether. This page sorts out the eight most useful contrast markers — mais, par contre, en revanche, cependant, néanmoins, toutefois, pourtant, or — by what each one actually does, where it sits in the sentence, and the register signal it carries.
The first thing to grasp is that these eight words do not form a synonym set. They split into three semantic families: simple opposition (mais, par contre, en revanche), concessive contrast (cependant, néanmoins, toutefois), and surprise contrast (pourtant, or). Within each family the differences are mainly stylistic; across families they are logical.
The headline summary
| Marker | Core meaning | Register | Position |
|---|---|---|---|
| mais | but (general) | neutral, universal | start of clause |
| par contre | on the other hand | informal/neutral | start of clause |
| en revanche | by contrast, on the other hand | formal/written | start of clause |
| cependant | however | formal/written | flexible |
| néanmoins | nevertheless | formal/written | flexible |
| toutefois | however, nevertheless | formal/written | flexible |
| pourtant | yet, and yet (surprise) | neutral | flexible |
| or | now, yet (new info) | literary/argumentative | start of sentence |
A working rule of thumb: mais in casual speech, cependant or toutefois in writing, par contre when speaking, en revanche when writing, pourtant when something surprises you. Refine from there.
Mais: the universal but
Mais is the workhorse. It is the closest French equivalent to English but and works in every register — from a child's playground complaint to a presidential speech. If you know only one contrast marker, mais will get you through any conversation.
J'aime le café, mais je ne peux pas en boire le soir.
I like coffee, but I can't drink it in the evening.
C'est petit, mais c'est confortable.
It's small, but it's comfortable.
Il a essayé, mais il n'a pas réussi.
He tried, but he didn't succeed.
Mais sits at the start of the second clause and links two propositions where the second contradicts an expectation set up by the first. Unlike all the other markers on this page, mais requires no judgement about register — it is always safe.
Mais as an emotional opener
A common spoken use of mais has nothing to do with logical contrast. Used at the start of a turn, mais expresses surprise, irritation, or insistence:
Mais qu'est-ce que tu fais ?!
What on earth are you doing?!
Mais oui, bien sûr !
Why yes, of course!
Mais non, ce n'est pas ce que j'ai dit.
No, that's not what I said.
These mais particles are emphatic discourse markers, not contrast operators. They are extremely frequent in spoken French and a clear marker of native fluency.
Par contre: on the other hand, informal
Par contre is the most-used (informal) contrast marker in spoken French. It introduces a counterpoint — on the other hand, however — typically when balancing two assessments of the same thing or person.
Le restaurant est cher. Par contre, la nourriture est excellente.
The restaurant is expensive. On the other hand, the food is excellent.
Je ne joue pas du piano, par contre je joue de la guitare.
I don't play the piano, but I do play the guitar.
Il parle anglais. Par contre, son français est terrible.
He speaks English. His French, however, is terrible.
The two clauses here are not really contradictory — they balance, and par contre signals here is the flip side. The marker sits at the start of the clause, sometimes set off by a comma, sometimes after a full stop.
Why grammarians used to hate par contre
For most of the 20th century, par contre was condemned by purists. Voltaire grumbled about it as a commercial barbarism, and the Académie française avoided it for decades. Today the prescription has loosened completely — par contre is recognised as standard everyday French — but its formal counterpart en revanche still sounds more elegant in writing.
En revanche: the formal counterpart
En revanche is (formal). It carries the same balancing meaning as par contre — on the other hand, by contrast — but it lives in writing, formal speech, and careful prose.
L'économie ralentit. En revanche, le secteur du tourisme reste dynamique.
The economy is slowing down. By contrast, the tourism sector remains buoyant.
Le vin rouge ne se conserve pas longtemps une fois ouvert. En revanche, le vin blanc peut tenir quelques jours au réfrigérateur.
Red wine doesn't keep long once opened. By contrast, white wine can last a few days in the fridge.
Il manque de patience. Il a en revanche une grande capacité de travail.
He lacks patience. On the other hand, he has a great capacity for work.
In the third example, en revanche sits inside the second clause rather than at its start — a position much more elegant than the equivalent slot for par contre would be. This mid-clause flexibility is one stylistic advantage of the formal alternatives.
Etymology, semantically alive
Revanche literally means revenge or return blow. The phrase en revanche originally meant in return, in compensation — and you can still feel that flavour in many uses. The first proposition presents one fact; the second presents a compensating counter-fact. This is not just however but here is what makes up for it.
Le projet est ambitieux. En revanche, le budget est limité.
The project is ambitious. On the other hand (in compensation, in return), the budget is limited.
Cependant: the workhorse of written French
Cependant translates as however and is the most common formal contrast marker in written French. It is (formal/written) but not as heavy as néanmoins.
Le projet semblait simple. Cependant, des difficultés ont surgi.
The project seemed simple. However, difficulties arose.
Elle a réussi son examen. Cependant, elle reste modeste.
She passed her exam. However, she remains modest.
La réunion a été productive. Cependant, plusieurs questions restent en suspens.
The meeting was productive. However, several questions remain unresolved.
Cependant is highly mobile in the sentence. It can sit at the start, in the middle (between subject and verb, or after the verb), or at the end:
La situation est cependant préoccupante.
The situation is, however, worrying.
Nous restons confiants. Le risque est réel, cependant.
We remain confident. The risk is real, however.
This positional flexibility makes cependant the marker of choice when you want to vary sentence rhythm in formal prose.
Néanmoins: nevertheless, the heavyweight
Néanmoins is the heaviest of the standard formal contrast markers — nevertheless, nonetheless. It is (formal) and signals that the second proposition stands despite the first.
Les preuves sont insuffisantes. Néanmoins, l'enquête se poursuit.
The evidence is insufficient. Nevertheless, the investigation continues.
Il pleuvait à verse. Néanmoins, le match a eu lieu.
It was pouring with rain. Nevertheless, the match took place.
Le rapport est imparfait ; néanmoins, il pose les bonnes questions.
The report is imperfect; nonetheless, it asks the right questions.
The flavour of néanmoins is concessive — yes, the first thing is true, but the second still holds. In speech it sounds bookish; in writing it is at home in journalistic, academic, and administrative prose.
Toutefois: however, written
Toutefois is also (formal/written) and overlaps with cependant in most uses. The difference is subtle: toutefois often introduces a caveat — however, with this reservation — while cependant introduces a counterpoint more neutrally.
Le traitement est efficace. Toutefois, il peut entraîner des effets secondaires.
The treatment is effective. However, it may cause side effects.
Vous pouvez consulter le document. Toutefois, vous ne pouvez pas le copier.
You may consult the document. However, you may not copy it.
Le vote a été clair. Il faudra toutefois confirmer le résultat.
The vote was clear. It will, however, need to be confirmed.
Toutefois is especially common in legal and administrative French where it introduces conditions and exceptions. In an everyday register it is interchangeable with cependant.
Pourtant: the surprise contrast
Pourtant is different from all the others. It does not balance two facts (par contre) or concede a point (néanmoins) — it expresses surprise. The second clause contradicts what you would have expected from the first.
Il a tout révisé. Il a pourtant raté l'examen.
He revised everything. And yet he failed the exam.
Pourtant, je l'avais prévenu !
And yet I warned him!
Elle ne mange presque rien, et pourtant elle prend du poids.
She eats almost nothing, and yet she's putting on weight.
The English equivalent is closer to and yet than however. Pourtant is neutral in register — fine in speech and writing, formal and informal — but it carries a clear emotional weight: the speaker is reacting to something puzzling.
A diagnostic test: if you can paraphrase the sentence as I would have expected the opposite, pourtant fits. If you cannot — if the two clauses just present two sides of an issue — par contre or en revanche is the right choice.
❌ Le restaurant est cher. Pourtant, la nourriture est excellente.
Awkward — these are not surprising opposites, just two attributes
✅ Le restaurant est cher. Par contre, la nourriture est excellente.
The restaurant is expensive. On the other hand, the food is excellent.
✅ Le restaurant est cher. Pourtant, il n'y a presque personne.
The restaurant is expensive. And yet it's almost empty. (surprise — you would expect the opposite)
Or: literary, argumentative new information
Or is the most specialised marker on this page. It belongs to (literary) and (argumentative) registers and introduces a new piece of information that bears on what came before — usually contradicting an assumption or extending a chain of reasoning.
Tous les hommes sont mortels. Or Socrate est un homme. Donc Socrate est mortel.
All men are mortal. Now, Socrates is a man. Therefore Socrates is mortal.
Il croyait avoir tout prévu. Or, un détail lui avait échappé.
He thought he had foreseen everything. But — one detail had escaped him.
Les sondages annonçaient une victoire facile. Or les résultats ont surpris tout le monde.
The polls predicted an easy victory. Yet the results surprised everyone.
Or always sits at the start of a sentence and introduces a piece of information that changes the trajectory of the argument. It is the marker of formal essays, classical syllogisms, news editorials, and literary narrative. In casual speech it sounds noticeably bookish — children sometimes mock it as parler comme un livre (talking like a book).
Side-by-side comparison
The same opposition realised with each marker, ranked roughly from casual to formal:
Le film est long, mais il est captivant.
The film is long, but it's captivating. (universal)
Le film est long. Par contre, il est captivant.
The film is long. On the other hand, it's captivating. (informal)
Le film est long. Pourtant, il est captivant.
The film is long. And yet it's captivating. (surprise — you would expect the opposite)
Le film est long. En revanche, il est captivant.
The film is long. By contrast, it's captivating. (formal)
Le film est long. Cependant, il est captivant.
The film is long. However, it's captivating. (formal)
Le film est long. Néanmoins, il est captivant.
The film is long. Nevertheless, it's captivating. (heavy formal)
All six are correct. The choice is partly logical — pourtant requires that long would normally make a film unwatchable, so the captivating quality comes as a surprise — and largely a register signal.
Position inside the clause
A useful stylistic note: cependant, toutefois, néanmoins, and en revanche can sit inside the second clause, not just at its start. This positioning is much more elegant in formal writing than always opening with the marker:
La proposition est, cependant, difficile à mettre en œuvre.
The proposal is, however, difficult to implement.
Le projet sera toutefois maintenu.
The project will, however, be maintained.
L'idée mérite néanmoins d'être étudiée.
The idea is nevertheless worth studying.
Mais, par contre, and or always open the clause and never slip inside.
Common mistakes
❌ J'aime le thé. Pourtant, je n'aime pas le café.
*Pourtant* requires surprise — disliking coffee is not surprising given liking tea
✅ J'aime le thé. Par contre, je n'aime pas le café.
I like tea. On the other hand, I don't like coffee.
❌ Le rapport est important. Par contre, nous vous remercions de bien vouloir le lire avant la réunion.
Register clash — formal letter requires *cependant* or *toutefois*
✅ Le rapport est important. Nous vous remercions cependant de bien vouloir le lire avant la réunion.
The report is important. We would, however, ask you to read it before the meeting.
❌ Mais cependant, je ne suis pas d'accord.
Don't double up two contrast markers
✅ Cependant, je ne suis pas d'accord.
However, I disagree.
❌ Or est-ce que tu viens ?
*Or* never starts a question; it introduces a new fact in argumentation
✅ Mais est-ce que tu viens ?
But are you coming?
❌ Il pleut. En revanche, je sors quand même.
*En revanche* balances two parallel facts; here you mean *pourtant* (surprise) or *mais quand même*
✅ Il pleut. Je sors quand même.
It's raining. I'm going out anyway.
❌ Salut, par contre, t'as vu mes clés ?
*Par contre* is not a topic-changer; for *by the way*, use *au fait*
✅ Salut, au fait, t'as vu mes clés ?
Hi, by the way, have you seen my keys?
The first error is the classic confusion between balanced contrast (par contre, en revanche) and surprising contrast (pourtant). English but covers both, so English speakers default to whichever French marker comes to mind, often the wrong one. The second is a register slip in business writing. The third is the doubled-marker mistake — pick one. The fourth uses or for what should be mais; or requires an argumentative chain, not an interrogative. The fifth confuses en revanche (balanced contrast) with pourtant or mais quand même (going-out-anyway concession). The sixth shows that par contre introduces contrast, never new topics.
A note on classroom par contre
Some traditional French teachers still tell students that par contre is wrong and only en revanche is correct. This prescription is outdated. Modern dictionaries (Larousse, Le Petit Robert) and the Académie française's current position both accept par contre in everyday usage. The sensible distinction is register: par contre in spoken and informal written French, en revanche in formal writing. Both are correct French.
Key takeaways
- All eight markers express contrast, but they split into three families: simple opposition (mais, par contre, en revanche), concession (cependant, néanmoins, toutefois), and surprise (pourtant, or).
- Mais is universal and always safe.
- Par contre is informal everyday; en revanche is its formal counterpart.
- Cependant, néanmoins, toutefois belong to written and formal registers and can sit inside the clause.
- Pourtant requires that the second clause be unexpected given the first — and yet, not just however.
- Or introduces a new piece of information in an argumentative chain. Literary or essay register.
- The most common learner error is using pourtant where balanced contrast (par contre, en revanche) is needed.

- Français Parlé vs ÉcritB1 — Spoken and written French are nearly two different languages. Spoken French drops 'ne,' elides schwas, prefers dislocation over inversion, uses 'on' for 'we,' and is punctuated by 'euh,' 'ben,' 'quoi,' and 'du coup.' Written French does almost none of this. Learning to operate in both is essential for fluency.
