Amélie · Learn French Learn French — Guides & Tips Tu vs Vous in French: The Rule, the Mistakes, the Fix
French has two words for “you”: tu (TEW) for one person you’re close to — friends, family, children, peers — and vous (VOO) for strangers, professional contacts, elders, and always for more than one person. The safe rule is brutally simple: when in doubt, use vous. Being too formal reads as well-mannered; being too familiar can read as disrespect.
English dropped this distinction centuries ago (that’s what “thou” was), which is why tu vs vous feels so foreign — it’s not just grammar, it’s a social signal baked into every sentence. The good news: the system runs on a handful of clear rules, and the French forgive learners almost everything. Let’s make you confident in it.
The rule in one table
| Situation | Use | Why |
|---|---|---|
| Friends and family | tu | Closeness is established |
| Children and teenagers (you’re an adult) | tu | Adults say tu to kids universally |
| Fellow students, teammates, peers your age in casual settings | tu | Peer contexts default to tu |
| Strangers, shopkeepers, waiters, taxi drivers | vous | No established closeness |
| Your boss, clients, officials, doctors | vous | Professional respect |
| Anyone noticeably older than you | vous | Age deference — let them propose tu |
| Online gaming, hobby forums, social media replies | tu | Internet culture defaults to tu |
| Any group of two or more people | vous | Vous is always the plural, formal or not |
That last row trips people up: vous does double duty. Addressing your two best friends is vous — not out of politeness, but because they’re plural. Context makes it unambiguous to French ears.
Pronunciation while we’re here: tu uses the pinched French u — say “ee” and round your lips as for “oo.” Vous is a plain “voo,” final s silent. Both vowels are covered properly in my guide to French pronunciation.
Why it matters more than you think
Tu and vous don’t just change one word — they conjugate the entire sentence:
- Tu as faim ? (tew ah FEH(N)) — “Are you hungry?” (informal)
- Vous avez faim ? (voo za-vay FEH(N)) — same question, formal or plural
- Comment t’appelles-tu ? vs Comment vous appelez-vous ? — “What’s your name?”
- Ça va ? works in both registers, which is one reason asking “how are you?” is such a safe opener.
The choice also carries real social weight. French even has verbs for it: tutoyer (tew-twah-YAY) — to address someone as tu — and vouvoyer (voo-vwah-YAY) — to address someone as vous. When a language needs dedicated verbs for a pronoun choice, you know the choice matters. Using tu with the wrong person can feel like an uninvited arm around the shoulder; clinging to vous with a close friend feels like shaking hands with your sister.
The decision guide, in 30 seconds
Run these three questions in order — the first “yes” decides:
- Is it more than one person? → vous, always, end of story.
- Would this person plausibly be a friend? Same generation, casual context, first names in use, or a child? → tu.
- Everything else — strangers, service staff, professional contacts, elders, anyone whose title you’d use? → vous.
A reliable shortcut: match the register of the greeting. If the situation calls for bonjour with a stranger, it calls for vous; if salut feels right, tu almost certainly does too. The greeting and the pronoun live in the same register — as covered in French greetings.
Switching from vous to tu: the little ceremony
Relationships in France often begin in vous and graduate to tu — and the switch is a small, genuinely warm ritual. The standard invitation:
— On peut se tutoyer ? (oh(n) puh suh tew-twah-YAY) — “Shall we switch to tu?” — Oui, bien sûr, avec plaisir ! — “Yes, of course, with pleasure!”
Or, offered as a statement: On se tutoie ? / Tu peux me tutoyer. (“You can call me tu.”)
The etiquette of who proposes it:
- The senior person offers. The older person, the boss, the professor — the one with more standing extends the invitation. Proposing tu upward is presumptuous.
- Accepting is near-mandatory. Refusing the offer is technically possible (Je préfère qu’on se vouvoie — “I’d rather we stay with vous”) but it’s a firm boundary-setting move.
- Once switched, never go back. Reverting to vous after tutoiement signals a relationship rupture — it’s how French speakers put someone coldly at arm’s length.
Teacher’s tip: in many modern workplaces — startups, creative fields, among colleagues of similar level — tu is immediate and automatic; imposing vous there would feel stiff. Traditional corporations, law, medicine, and government still run on vous. On day one, listen for how colleagues address you, and mirror it.
The mistakes, ranked by damage
Barely matters — using vous when tu was expected. Worst case, you sound charmingly formal, and someone smiles and says on peut se tutoyer ! This is why vous is the default: the failure mode is polite.
Noticeable — using tu with service staff or strangers. Saying tu to a waiter, taxi driver, or shopkeeper you don’t know reads as condescending, even though foreigners get a wide benefit of the doubt. A quick pardon, vous… self-correction fixes everything.
Actually costly — using tu in formal professional settings. With a client, an interviewer, a French administration official, or an older business contact, an unearned tu can genuinely undercut you. These are exactly the rooms where the vous reflex pays for all the practice.
The learner’s classic — mixing them mid-sentence. Vous pouvez me passer ton stylo ? (“Can you [formal] pass me your [informal] pen?”) French people find this endearing rather than rude, but consistency is the mark of control: pick the pronoun, and make every verb and possessive follow it (ton/ta/tes with tu, votre/vos with vous).
And one reassurance, because learners genuinely fear this: no French person is offended by a struggling foreigner’s pronoun choice. The rules above are for sounding polished — not for avoiding disaster. The French know their system is hard; the attempt is what earns the goodwill.
FAQ
What’s the basic difference between tu and vous?
Both mean “you.” Tu addresses one person informally — friends, family, kids, peers. Vous is for one person formally — strangers, professionals, elders — and for any group of people, formal or not. The sentence’s verbs change with the choice: tu as but vous avez.
When in doubt, should I use tu or vous?
Vous, always. Excess formality is read as good manners and, at worst, gently corrected with an invitation to switch. Excess familiarity is the direction that can offend. There is no situation where a polite vous to a single stranger gets you in trouble.
What do tutoyer and vouvoyer mean?
They’re the French verbs for the choice itself: tutoyer = to address someone as tu; vouvoyer = to address someone as vous. You’ll hear them constantly in the negotiation: On peut se tutoyer ? (“Shall we use tu?”) is the standard, friendly way to propose switching.
Do French people use tu with waiters and shopkeepers?
No — service interactions run on vous in both directions, even when everyone involved is young and the tone is friendly. A waiter says vous to you; you say vous back. Regulars at a neighborhood café may eventually graduate to tu with staff they’ve known for years, but that’s earned, never assumed.
Can I use tu on social media and in games?
Yes — internet French defaults to tu almost everywhere: gaming, Twitter/X replies, Reddit, Discord, YouTube comments. Writing vous to one person online sounds oddly stiff, like wearing a suit to a barbecue. The exception is professional platforms like LinkedIn, where vous remains standard between people who don’t know each other.
