French Conditional Tense: How to Say 'Would' in French

You're at a friend's dinner table in Lyon, and they ask if you'd like more wine. Your brain reaches for je veux plus de vin -- technically correct, but it comes out sounding like a toddler demanding juice, not a guest making a polite request. The word you actually needed was je voudrais, and the tense behind it -- French's conditional tense, the conditionnel -- is one of the fastest ways to sound like a considerate adult instead of a blunt beginner.

The conditional isn't just about politeness, though that's where most learners meet it first. It's also how French expresses hypotheticals (what would happen if...), gives advice (what you would do in someone else's place), and reports what someone said about the future from a past vantage point. English handles all of this with a single word, would, dropped in front of a verb -- I would like, I would go, she said she would come. French instead conjugates the verb itself into a distinct tense, which means there's no shortcut: you either know the conditional forms, or every "would" sentence you try to build stalls halfway through.

The good news is the conditionnel présent doesn't need a new set of endings memorized from scratch -- it borrows both halves from tenses you likely already know. Take the same stem you'd use for the futur simple (for regular verbs, that's just the infinitive) and attach the imparfait endings: -ais, -ais, -ait, -ions, -iez, -aient. Parler (to speak) gives je parlerais, tu parlerais, il/elle parlerait, nous parlerions, vous parleriez, ils/elles parleraient -- every form sounds like the future tense with an imperfect ending swapped on. Finir (to finish) works the same way: je finirais, tu finirais, il finirait. For -re verbs, drop the final e from the infinitive before adding the endings: vendre (to sell) becomes je vendrais, not je vendreais.

A handful of very common verbs use an irregular stem instead of their infinitive -- and it's the exact same irregular stem the futur simple uses, so if you already know one tense, you already know the other's foundation. Être (to be) uses ser-: je serais (I would be). Avoir (to have) uses aur-: j'aurais (I would have). Faire (to do/make) uses fer-: je ferais (I would do). Aller (to go) uses ir-: j'irais (I would go). Vouloir (to want) uses voudr-: je voudrais (I would like). Pouvoir (to be able to) uses pourr-: je pourrais (I could/would be able to). Devoir (to have to) uses devr-: je devrais (I should/would have to). Venir (to come) uses viendr-: je viendrais (I would come). These eight cover the overwhelming majority of conditional sentences you'll actually build, so they're worth memorizing as a set rather than looking each one up as it comes up.

The single most useful everyday job of the conditional is softening a request. Je veux (I want) is grammatically fine but can land as blunt or even rude in French, the way "I want a coffee" sounds pushier in English than "I'd like a coffee." Swap it for je voudrais (I would like) and the same sentence turns into the standard, polite way to order, ask, or request almost anything in French: je voudrais un café, s'il vous plaît (I'd like a coffee, please). J'aimerais (I would like/love to) works the same softening job for wishes and invitations -- j'aimerais visiter le Japon (I'd love to visit Japan). Formal questions get the same treatment: pourriez-vous...? (could you...?) and auriez-vous...? (would you have...?) are the go-to polite question openers in a shop, a hotel, or an email, replacing the blunter pouvez-vous and avez-vous. [AUDIO: je voudrais] [AUDIO: pourriez-vous] This isn't a minor nicety -- in French service culture, reaching for je veux instead of je voudrais with a stranger, a waiter, or a shopkeeper is one of the fastest ways an otherwise fluent-sounding sentence reads as abrupt.

The conditional is also the second half of French's most common hypothetical structure: si (if) plus the imparfait in one clause, paired with the conditionnel in the other. Si j'avais le temps, je voyagerais plus (If I had the time, I would travel more) -- notice avais is imparfait, while voyagerais is conditional; the two never both take the conditional form, even though it's tempting to reach for "would" logic in both halves the way English sometimes does. This is the single most common mistake with this structure: writing si je serais riche instead of the correct si j'étais riche, je serais riche (if I were rich, I would be rich). The si-clause always stays in the imparfait; only the result clause takes the conditional.

Two more everyday uses round out the picture. For advice, à ta place (in your place/if I were you) pairs naturally with the conditional: à ta place, je lui parlerais (in your place, I'd talk to them). And for reporting what someone said about the future, the conditional steps in wherever English would normally use "would" inside reported speech: il a dit qu'il viendrait (he said he would come) -- the original statement, il viendra (he will come), shifts from futur simple to conditionnel once it's wrapped inside a past-tense sentence, the same way English shifts "will" to "would."

Picture yourself back at that dinner table, this time ready. Your host asks, Tu veux encore du vin ? (Do you want more wine?) Instead of the blunt oui, je veux, you answer: Oui, je voudrais bien, merci (Yes, I'd like some, thank you) -- bien here just adds warmth, the way "I'd love some" is warmer than a flat "yes." Later in the evening, talking about a trip you're both dreaming about, you might say: Si j'avais plus de vacances, j'irais en Grèce cet été (If I had more vacation time, I'd go to Greece this summer) -- imparfait in the if-clause, conditional in the result, exactly the pattern above.

Try it yourself. 1) Conjugate vouloir in the conditional for je: je ___ un thé, s'il vous plaît. 2) Fix the mistake: Si je serais toi, je partirais maintenant. 3) Translate to French using the conditional: "I would love to visit Paris." 4) Fill in the blank with the correct tense: Si elle avait plus de temps, elle ___ (lire) plus de livres. 5) Translate, using a polite conditional question: "Could you close the window?" 6) Fill in the blank: Il a dit qu'il ___ (venir) à la fête.

Answer key: 1) je voudrais un thé, s'il vous plaît. 2) The fix is Si j'étais toi, je partirais maintenant -- the si-clause needs the imparfait, not the conditional. 3) J'aimerais visiter Paris. 4) elle lirait -- si + imparfait pairs with a conditional result clause. 5) Pourriez-vous fermer la fenêtre ? 6) viendrait -- venir's conditional stem is viendr-, matching its futur simple stem.

Three things to carry forward: the conditionnel présent is built from the same stem as the futur simple plus imparfait endings, so learning one tense gives you most of the other for free. Si-clauses always keep the imparfait in the if-half and save the conditional for the result. And swapping je veux for je voudrais is one of the smallest changes that makes the biggest difference in how polite your French sounds. Ready to make it automatic?
