When to use vous or tu in French

I made a huge mistake after I started dating Brian when I met his parents. I was visiting France for the first time, and we were sitting around the table gorging on Aperol and chips while laughing and having ‘what’s France like compared to America’ conversations. Standing next to Bri’s mom, I nonchalantly swirled my drink around while exclaiming, “Mais, oui, c’est evident, mais tu sais.” Joce looked at me with a strange eye, I didn’t realize it then but I was starting on a journey of irreversible grammatical errors. The rest of the summer I filled with tus mirroring their language and following Brian.

I didn’t realise my mistake for another year, until I finally moved to France. Bri’s grandmother was over for dinner and we were eating when I noticed Joce motioning to Madame Corrieri and saying, “Voulez-vous un autre tranche du boeuf?” I stared for a moment and it sunk in. Aghast I leaned over to Bri and said, “Omg. Am I supposed to be using vous with your parents? Like since the beginning?” He looked at me and nodded, like, duh! I was aghast. I didn’t know how to discuss this with his parents and be like, “So can we go back to the vous or is it too late?”

Luckily, I have understanding French in-laws, and when I finally knew enough French to be able to make conversation on my own I posed the question: “C’est ok si j’avais toujours appelé toi un tu, pourrais-je changer?” She laughed and said, “C‘est pas nécessaire.” I nodded.

Thus, I embarked on the horrible journey of deciding when to use the tu and when to use the vous. I’ve sort of broken down some social rules.

When to use the tu

  • With other students that are in your class.
  • With close friends or people that are your age.
  • Anyone who is younger than you.
  • When someone has requested it, a true French social thing: Tu peux m’appelle tu.

When to use the vous

  • Professors or bosses.
  • Colleagues at work.
  • Anyone who is older than you, at least by a generation.
  • Anyone you meet in a store.
  • Parents/grandparents of your French boyfriend.
  • Addressing a group of people.

It can be incredibly annoying, as all those verb forms change and if you make the social mistake of calling someone a vous when they are clearly a tu, you risk looking too formal. And vice versa. Just don’t call your boyfriend’s parents tu. That is a bad and irreversible mistake.

Frequently Asked Questions

What formal vocabulary do you use when addressing people in French?
'Vous' is the formal way to address adults you don't know well, people older than you, or in professional settings. 'Monsieur' and 'Madame' prefix names when using vous. Using tu (informal) with someone you've just met is disrespectful. The vous/tu distinction reflects French social hierarchy. Learning when to use each is crucial for integration and social respect.
When should you use 'tu' (informal you) in French?
Use tu with friends, family, children, and people you've built familiarity with. Many French people are comfortable with tu after brief acquaintance if they suggest it. Workplace dynamics vary: some offices use tu throughout, others use vous. When uncertain, use vous and wait for invitation to use tu. Making this mistake is more forgivable than overusing familiarity.
What are the consequences of using the wrong form of 'you' in French?
Using tu with someone expecting vous can be perceived as rude or disrespectful. Using vous with friends might seem cold or distant, creating awkwardness. Native speakers are usually forgiving to foreigners, but making an effort shows respect for culture. Learning context and conventions helps avoid these social mistakes and integrate better.
How do French workplace formalities differ from other countries regarding 'vous' and 'tu'?
French workplaces vary: some use vous throughout, others use tu even in formal settings. Hierarchy, age, and industry influence expectations. Traditional industries (law, banking) more formal. Tech companies more casual. Ask colleagues what they prefer. Following the team's established norms shows professionalism and social awareness important for career success.

I told everyone I was moving to Paris for a museum internship. That was technically true. But really, I just wanted to eat croissants for breakfast every day. Seven years later, I'm still here, still eating croissants, and now I help others navigate French administration without losing their minds.
