Tu vs Vous: The French Formality Rule
English flattened “thou” and “you” into one word centuries ago, so French speakers have to constantly manage a social distinction that English speakers don’t even think about. Tu and vous both mean “you,” but choosing wrong can land somewhere between “a little awkward” and “genuinely rude,” depending on the context.
The short version
- Tu is informal singular — friends, family, children, peers your age, and anyone who’s explicitly invited you to use it.
- Vous is formal singular, or ANY plural regardless of formality — strangers, elders, professional contexts, and groups of people.
When you’re not sure, default to vous. Being overly formal is a minor social hiccup; being overly familiar can genuinely offend.
When to use tu
- With friends: Tu veux venir ce soir? (Do you want to come tonight?)
- With family: Tu as bien dormi? (Did you sleep well?)
- With children, always, regardless of how well you know them: Comment tu t’appelles? (What’s your name?)
- With peers your age in casual settings: students, young colleagues at informal companies.
- With pets, which always get tu, and with God in religious/poetic French, interestingly.
When to use vous
- With strangers: Excusez-moi, vous avez l’heure? (Excuse me, do you have the time?)
- With elders or people clearly above you in age or status: Comment allez-vous? (How are you?)
- In professional or formal settings, even with colleagues you like: Vous pouvez m’envoyer le rapport?
- Speaking to more than one person, no matter how close you are to them: Vous venez tous les deux? (Are you both coming?)
- With service staff you don’t personally know: waiters, shopkeepers, receptionists.
Quick chart
| Tu (informal singular) | Vous (formal or plural) |
|---|---|
| Friends, family, kids | Strangers, elders, formal contexts |
| Casual peers | Any group, regardless of familiarity |
| Invited familiarity — “on peut se tutoyer?” | Default until invited otherwise |
| Verb: tu as, tu es, tu fais | Verb: vous avez, vous êtes, vous faites |
| Pets, close family | Service staff, professional emails |
The moment of switching: tutoyer and vouvoyer
French has actual verbs for this social maneuver — tutoyer means to address someone with tu, and vouvoyer means to address them with vous — and the switch from one to the other is a real, sometimes explicitly negotiated social moment. It’s completely normal for a French speaker to ask On peut se tutoyer? (“Can we use tu with each other?”) after a few meetings, essentially requesting to move the relationship to informal footing. Until that invitation happens, staying with vous is the safe, respectful default, and switching to tu without an invitation — especially with someone older or in a position of authority — can come across as presumptuous. This varies somewhat by country: francophone Quebec tends to use tu more liberally and faster than France does, even in some professional settings, so what counts as “too familiar” shifts depending on which French-speaking region you’re in. Workplace culture also matters enormously within France itself — some modern, informal companies (especially tech startups) use tu company-wide regardless of seniority, while traditional firms keep vous strictly in place even between colleagues who’ve worked together for years. When traveling or working across regions and industries, matching the local norm matters more than applying one fixed rule everywhere.
Mistakes learners make
- Using tu with a stranger, shopkeeper, or waiter — this reads as disrespectful even if you didn’t intend it that way.
- Sticking with vous long after someone has clearly invited tu, which can feel oddly cold or overly formal.
- Using tu with a single person but forgetting that vous is also required for any group, even a group of close friends.
- Mixing tu and vous verb forms within the same sentence out of uncertainty — pick one and stay consistent.
- Assuming workplace norms are the same everywhere — a tu-friendly startup culture doesn’t transfer to a traditional French company.
Frequently asked questions
What’s the difference between tu and vous?
Tu is informal, used with friends, family, children, and peers. Vous is formal singular, used with strangers and elders, and it’s also the only option for addressing more than one person.
When should you use vous instead of tu?
Use vous by default with anyone you don’t know well, anyone older or in a position of authority, and always when speaking to a group, regardless of how close you are to them.
Can you ask someone if you can use tu with them?
Yes — On peut se tutoyer? is a common, polite way to ask if you can switch from vous to tu, essentially requesting a shift to informal footing.
Is vous always plural?
No. Vous is used both as the formal singular “you” and as the plural “you,” for any group size, whether the group is close friends or strangers.
Do French speakers in Quebec use tu differently than in France?
Yes, generally. Quebec French tends to use tu more freely and in more contexts, including some professional settings, than European French typically does.
What happens if you use tu with the wrong person?
It can come across as overly familiar or disrespectful, especially with strangers, elders, or people in authority. When in doubt, vous is the safer choice.
Do French children use vous with their own parents?
Rarely in most families today — tu is standard between parents and children. Vous with a parent is unusual and tends to signal either a very formal family tradition or a distant relationship.
Can you switch back to vous after starting with tu?
It’s unusual and can feel like a deliberate signal of distance or displeasure — once a relationship moves to tu, reverting to vous is a noticeable social move, not a neutral one.
Getting tu and vous right is as much about social judgment as grammar. corrector.co’s free French checker flags inconsistent tu/vous verb forms within the same piece of writing.
