How to Say Yes in French: Oui, Ouais, Si and More

How do you say yes in French?

The standard word for yes in French is oui. It’s pronounced almost exactly like the English word “we.” It’s neither formal nor informal, so you can use it in any situation, with anyone.

If you only remember one word, oui is it. But if you want to sound like a real speaker, a few more options are worth knowing. They’ll also help you understand what you hear, because spoken French rarely sticks to a textbook oui.

Tip: a clear oui with a nod is perfectly polite. You don’t need to add anything to be understood.

Ouais: the casual yes you’ll hear everywhere

In everyday spoken French, ouais (it sounds like “way”) is arguably more common than oui. It’s the relaxed, informal version, a bit like “yeah” in English.

Use it with friends and family. In a formal setting, a job interview, or with someone you address as vous, stick to oui. For more of these everyday building blocks, see our list of useful French phrases.

Si: the special French yes

This is the one that surprises English speakers. French has a second word for “yes,” si, used only to contradict a negative question or statement.

For example: someone says Tu n’aimes pas le café ? (“You don’t like coffee?”). If you do like it, you don’t answer oui, you answer Si ! (“Yes, I do!”). Using oui here would sound off to a French ear.

• Tu ne viens pas ? → Si, j’arrive ! (“You’re not coming?” → “Yes, I am!”)
• Ce n’est pas vrai. → Si, c’est vrai ! (“That’s not true.” → “Yes, it is!”)
• Tu n’as pas faim ? → Si, un peu ! (“You’re not hungry?” → “Yes, a little!”)

Other ways to agree in French

“Yes” isn’t always a plain oui. Depending on what you mean, here are the most useful alternatives:

• D’accord → “okay / alright,” to agree with a suggestion (literally “in agreement”).
• Ça marche → “works for me,” casual and very common to accept a plan.
• Volontiers → “gladly,” the polite way to accept an offer (like a drink).
• Ben oui → “well, yeah,” when the answer feels obvious.
• Exactement / tout à fait → “exactly / absolutely,” to strongly agree with what someone said.

For example: offered a coffee, a simple Volontiers ! sounds far nicer than a flat oui.

How to say an emphatic yes

When you really mean it, French gives you punchier options:

• Bien sûr → “of course,” a warm, confident yes.
• Carrément → “totally / for sure,” casual and enthusiastic.
• Absolument → “absolutely,” strong and a touch formal.
• Avec plaisir → “with pleasure,” gracious and warm.
• Grave → slang for “totally,” very informal among young people.

Mouais: the hesitant yes

Add an “m” to ouais and you get mouais (or mouich), the unconvinced yes. It signals doubt or reluctance, the French equivalent of “meh, I guess.” It’s very expressive and very common in casual speech.

You’ll also hear ouaip, a playful “yep,” and bof, which leans toward “meh, not really.” These casual forms are everywhere once you start listening. If you enjoy that informal side of the language, you’ll like our guide to French slang words.

Oui or si: which yes do you need?

Here’s the rule of thumb that saves you every time:

• Answering a normal question (Tu viens ?) → oui.
• Answering a negative question to say “yes, actually” (Tu ne viens pas ?) → si.

That single distinction is what separates a confident speaker from a hesitant one, so it’s worth a little practice.

A quick guide to choosing the right yes

To keep it simple:

• Neutral, works anywhere: oui
• Casual, with friends: ouais
• Contradicting a negative question: si
• Agreeing to a plan: d’accord, ça marche
• Emphatic: bien sûr, tout à fait, carrément
