Level Level A2 (around the DELF A2 exam). Real French: rearranging plans with a friend by text and phone.

What it is

Your mission: your friend Sarah asks, « Tu veux venir au cinéma samedi ? » You can't: you have to work. Say no kindly, explain why, and suggest another day she can manage.

Three key verbs, all irregular, all followed by an infinitive:

pouvoir (can)vouloir (want)devoir (must, have to)
jepeuxveuxdois
tupeuxveuxdois
il / elle / onpeutveutdoit
nouspouvonsvoulonsdevons
vouspouvezvoulezdevez
ils / ellespeuventveulentdoivent
  • Je peux venir. I can come.
  • Tu veux sortir ? Do you want to go out?
  • Je dois travailler. I have to work.

Il faut + infinitive = "you have to / we need to", without saying who: Il faut réserver. (We need to book. / You have to book.)

Negative: ne … pas goes round the conjugated verb: Je ne peux pas venir.

    Show answer

    doivent. ils doivent + infinitive.

Why it matters

Plans change all the time, and saying "I can't, I have to…, can we…?" politely is a core everyday skill. These three verbs also let you ask permission (Je peux… ?), make offers (Tu veux… ?) and give obligations (Il faut…), so they unlock a lot of conversation with very little grammar.

Worked example

By phone with Sarah:

  • Sarah: Tu veux venir au cinéma samedi ?
  • You: Ah, je suis désolé(e), je ne peux pas. Je dois travailler samedi.
  • Sarah: Dommage ! Tu peux dimanche ?
  • You: Oui, dimanche je peux. Mais il faut réserver, non ?
  • Sarah: Oui, je veux bien m'en occuper. On se retrouve à 18 h ?
  • You: Parfait, à dimanche !

Real French: Je veux bien means "I'd be happy to / yes, gladly", softer than a plain je veux. And to sound polite when asking for something, French uses je voudrais rather than je veux: that's coming up in a later mission.

Common mistake

Conjugating the second verb: wrong: Je peux viens. After pouvoir, vouloir, devoir and il faut, the second verb stays in the infinitive: Je peux venir.

And il faut never changes its subject: wrong: je faut, wrong: nous faut. It's always il faut.

Practise speaking

Studyfern has no voice tools of its own. To practise out loud, copy this prompt into a voice-capable AI assistant and talk with it.

Mission role-play. You are Sarah, my French friend, inviting me to the cinema on Saturday by phone. Speak naturally but clearly, at level A2, using tu. Start with « Tu veux venir au cinéma samedi ? ». I can't come on Saturday. Ask why, then suggest other days and times one at a time; accept one of my suggestions in the end. After each of my answers, tell me in English what kind of mistake I made, if any, and let me try again; watch the infinitive after pouvoir, vouloir, devoir and il faut. When I have said no politely, given a reason with devoir, suggested another day with pouvoir, and we have agreed a time, say « Mission accomplie ! » and give me one tip. Keep every reply under 3 sentences.

Listen too. Listen to native speakers before and after: see the free listening and shadowing links.

Good to know. AI feedback on pronunciation is hit and miss, so check yourself against native recordings. Many assistants turn your speech into text first, so a vowel or liaison you got wrong may be silently “heard” as the right word. Don't share personal details: use a made-up name and town.
