Why this matters

Modal verbs are the ones that color every other verb. "I want to go." "You must arrive on time." "She knows how to cook." In French, three key modals — vouloir, devoir, savoir — unlock an enormous range of expression. Together with pouvoir from Day 3, these four modals are the engine of French conversation. On the DELF A2 oral exam's role-play section, vouloir and devoir appear constantly (ordering in a restaurant, negotiating a schedule), so fluency here directly affects your score.

🦝 Remy says: "Modals are like seasoning — they make everything more interesting. Once you have these, you can express your desires, obligations, and abilities. That's basically half of all conversations right there."

Document Déclencheur

Post-it, cuisine partagée Je dois partir tôt demain, désolée pour le bruit. Tu sais où est la clé de la cave ? Je ne la trouve plus. Je veux bien t'aider à déménager samedi si tu veux !

What do you notice?

"Je dois partir" and "je veux bien t'aider" both pair a modal with an infinitive — can you find both modal verbs? (devoir, vouloir)
"Tu sais où est la clé" — why savoir here and not connaître? (savoir + a question word/fact, not knowing a person or place — connaître would be used for "Tu connais la cave ?")
"Je veux bien" is softer than a plain "je veux" — what does adding "bien" do to the tone? (it turns a blunt "I want" into a warmer, more polite offer, closer to "I'd be happy to")

VOULOIR — To Want

Pronoun	Form	Example
je	veux	Je veux un café, s'il vous plaît. = I want a coffee, please.
tu	veux	Tu veux venir ? = Do you want to come?
il/elle	veut	Elle veut partir. = She wants to leave.
nous	voulons	Nous voulons essayer. = We want to try.
vous	voulez	Vous voulez quoi ? = What do you want?
ils/elles	veulent	Ils veulent rester. = They want to stay.

Politeness tip: In shops and restaurants, say je voudrais (I would like) instead of je veux — it's much more polite.

Je voudrais un croissant. = I would like a croissant.
Nous voudrions réserver une table. = We would like to book a table.
Tu veux du thé ou du café ? = Do you want tea or coffee?

DEVOIR — To Have To / Must

Pronoun	Form	Example
je	dois	Je dois travailler demain. = I have to work tomorrow.
tu	dois	Tu dois arriver à l'heure. = You must arrive on time.
il/elle	doit	Il doit partir. = He has to leave.
nous	devons	Nous devons partir maintenant. = We must leave now.
vous	devez	Vous devez réserver. = You must make a reservation.
ils/elles	doivent	Elles doivent étudier. = They have to study.

Devoir can also express probability: Il doit être fatigué. = He must be tired (probably is).

Tu dois avoir faim après ce voyage. = You must be hungry after that trip.

SAVOIR — To Know (a fact / how to do something)

Pronoun	Form	Example
je	sais	Je sais parler espagnol. = I know how to speak Spanish.
tu	sais	Tu sais nager ? = Do you know how to swim?
il/elle	sait	Elle sait cuisiner très bien. = She knows how to cook very well.
nous	savons	Nous savons la réponse. = We know the answer.
vous	savez	Vous savez où c'est ? = Do you know where it is?
ils/elles	savent	Ils savent tout ! = They know everything!

SAVOIR vs CONNAÎTRE: Both mean "to know" but used differently:

Savoir = to know a fact or know how to do something: Je sais qu'il est là. / Je sais conduire. / Tu sais si le magasin est ouvert ?
Connaître = to know a person or place: Je connais Paris. / Je connais Marie. / Nous connaissons ce restaurant.

Mini-dialogue — deciding on weekend plans:

Inès : Tu veux sortir samedi ? Je connais un super restaurant. (Do you want to go out Saturday? I know a great restaurant.)
Karim : Je dois d'abord finir un projet, mais je sais que j'aurai le temps le soir. (I have to finish a project first, but I know I'll have time in the evening.)
Inès : Parfait ! Tu sais où se trouve la rue Lamartine ? (Perfect! Do you know where Lamartine street is?)
Karim : Oui, je connais bien ce quartier. (Yes, I know that neighborhood well.)

🦝 Remy's memory trick: "Devoir and vouloir both follow the same pattern: je/tu get the same form, il/elle adds a 't'. Noticing patterns between irregular verbs makes them feel less scary. They're not so irregular after all!"

Common Mistakes

❌ Je connais parler français. → ✅ Je sais parler français. — connaître can never be followed directly by an infinitive; use savoir for skills/abilities.
❌ Il doit à travailler. → ✅ Il doit travailler. — devoir, like pouvoir and vouloir, takes the infinitive directly, no "à" needed.
❌ Je veut un café. → ✅ Je veux un café. — the je form of vouloir is veux, not veut (which is il/elle).
❌ Je connais que Paris est joli. → ✅ Je sais que Paris est joli. — a fact/opinion introduced by "que" always uses savoir, never connaître.

Recap

VOULOIR, DEVOIR, and SAVOIR follow a shared irregular pattern: je/tu identical, il/elle adds -t, nous/vous regular-looking, ils/elles add -ent.
Use je voudrais instead of je veux for politeness in shops and restaurants.
Devoir can express obligation or probability depending on context.
Savoir = facts and skills; connaître = people and places — never mix them up.

🎯 Today's challenge

Write five sentences about yourself using today's verbs: what you want to do this week, what you have to do, and what you know how to do. Be honest — learning a language means talking about real life!

⭐ Key takeaways

VOULOIR (veux/veux/veut/voulons/voulez/veulent) — express desires. Use voudrais for polite requests.
DEVOIR (dois/dois/doit/devons/devez/doivent) — express obligations, duties, or probability.
SAVOIR (sais/sais/sait/savons/savez/savent) — knowing facts or skills; different from connaître, which is for people/places.
Mixing up savoir and connaître is the single most common modal-verb error at this level — check whether you're talking about a fact/skill or a person/place.
