You walk into a bakery in Lyon. The baker smiles and asks how your day is going. Do you answer with tu or vous? This tiny choice trips up almost every French learner, and the fear of getting it wrong keeps many people quiet. The good news is that the rule behind it is clearer than most grammar books make it sound.
What the two words actually mean
French has two second-person pronouns. Tu is singular and informal. Vous is the plural you, and it is also the singular formal you. So when you talk to a group, you always use vous, as in Vous êtes fatigués (you all are tired). When you talk to one person, you pick based on closeness and respect.
The informal tu signals familiarity. The formal vous signals distance or politeness. English lost this distinction centuries ago, which is exactly why it feels strange at first. You are not just choosing a word. You are deciding how close you want to sound.
When vous is the safe default
If you are unsure, use vous. It never offends. Strangers get vous: shopkeepers, waiters, people on the street, taxi drivers. Anyone older than you whom you do not know gets vous. Bosses and colleagues you are not friendly with get vous too, at least until the office culture relaxes.
Service situations are simple. The person helping you is a stranger, so you say Vous avez du pain (do you have bread) and Vous pouvez m’emballer (you can wrap it). Using tu with a stranger can read as rude or oddly familiar, even when your accent makes it obvious you are a learner.
When tu starts to feel natural
Some people always get tu, no matter your age or status. Use tu with:
- Children and babies, including those of strangers
- Your pets and the pets of friends
- Close friends and family members
- Peers around your own age once you know them a little
French friends will often invite you to switch. You will hear On se tutoie? (shall we use tu) or simply Tutoiementoi (let’s use tu). That is your cue. Accept it and relax into tu for that person from then on.
The middle ground and how to switch
The awkward part is the transition. You might use vous with a neighbor for months, then become friends. When they suggest tu, switch without apology. Staying on vous after the offer can feel cold. In writing, the same logic applies. Emails to a company use vous. Messages to a new friend shift to tu once you meet in person.
One trap: do not mix them in the same sentence to one person. Pick one and stay consistent until the relationship changes. If you slip, French speakers are forgiving. They know the system is a puzzle for newcomers.
Reading real French is the fastest way to absorb these social cues. In our news articles written for learners, you will see vous in polite reporting and tu in interviews with friends and stars. Notice who gets which, and the instinct will settle in. Pick one article at your level today and read it while asking yourself why each speaker chose the pronoun they did.
