French Question Words: Master the Common Question Words in French

It occurs to you that asking questions is unavoidable for traveling... Good call, because asking questions is basically half of any conversation when learning French. Whether you're trying to figure out where the bathroom is, when the train leaves, or who ate your croissant, you need to know how French question words work. The good news is that French has three main ways to form questions, and once you get the hang of them, you'll be asking away like a local. Let's break down everything you need to know about French question words and how to actually use them.🧐

The three ways to form questions in French

Before we dive into specific question words, you need to understand that French has three different methods for forming questions. Each one has a different vibe and formality level.

Intonation (The casual way to ask a question)

This is the easiest method and the one you'll hear most in everyday conversation. You literally just say a regular sentence and raise your voice at the end. That's it.

Pretty straightforward, right? This works great for casual situations with friends, family, or people your age. You'll hear this constantly in real French conversations.

Est-ce que (The middle ground)

This method sits right between casual and formal. You take "est-ce que" and stick it at the beginning of a regular sentence. The word order stays normal, which makes it easier for learners.

This works in most situations and sounds natural without being too stiff. You can use est-ce que pretty much anywhere without sounding weird.

Inversion (The formal way)

This is the fancy method where you flip the subject pronoun and verb. You'll see this in formal writing, official situations, and when people want to sound proper.

Notice that hyphen connecting the verb and pronoun? That's required. And see that extra "t" in "arrive-t-il"? When a verb ends in a vowel and the pronoun starts with one, French throws in a "t" to make pronunciation easier.

Essential French question words you need to know

Alright, here's where we get into the actual question words. French has the standard set you'd expect, plus a few quirks that trip people up.

Qui (Who)

This one's pretty straightforward. Qui means "who" and it works for both subjects and objects.

When qui is the subject of the sentence, you can also use "qui est-ce qui" for emphasis, though it sounds more formal.

You'll also see "qui est-ce que" when qui is the object:

Honestly though, most people just stick with qui in casual conversation.

Que and quoi (What)

Here's where French gets annoying. Both que and quoi mean "what" but you use them in different situations.

Que is more formal and typically comes at the beginning of questions:

Notice how que becomes qu' before a vowel? That's standard French contraction stuff.

Quoi is more casual and usually comes at the end of questions or after prepositions:

In everyday speech, you'll hear quoi way more often than que. The intonation method with quoi at the end is super common.

Où (Where)

This question word is your friend when you need directions or want to know locations.

That last one uses the preposition "de" (From) combined with où. When you see "d'où" it's asking about origin or source.

Pretty simple. Où is où, no weird variations to worry about.

Quand (When)

Use quand for any time-related questions.

Quand works the same way across all three question formation methods, so no surprises here.

Pourquoi (Why)

This one's for asking reasons and explanations.

When someone asks you pourquoi, the typical way to answer is with "parce que" (Because).

Comment (How)

Comment asks about manner, method, or condition.

You can also combine comment with other words for more specific questions:

Combien (How much/How many)

Use combien for quantities, prices, and numbers.

Notice that combien often pairs with the preposition "de" when followed by a noun.

Quel (Which/What)

Quel is actually an interrogative adjective, so it changes based on gender and number. You've got quel (Masculine singular), quelle (Feminine singular), quels (Masculine plural), and quelles (Feminine plural).

The pronunciation is basically the same for all of them, but you need to match the written form to whatever noun follows.

Yes or no French questions in French grammar

Sometimes you just need a simple yes or no answer. All three question formation methods work here.

The answer comes back as "oui" (Yes), "non" (No), or "si" (Yes, contradicting a negative question).

The 5 W's in French language learning

If you're familiar with the journalism basics, the 5 W's in French are:

Some people add comment (How) to make it six, but the core five cover most of what you need for basic information gathering.

Common patterns you'll use to ask a question in French

Let me give you some real-world examples that come up constantly.

Formal versus informal way to ask questions

Here's the thing about French questions. The formality level matters a lot depending on who you're talking to.

With friends, family, or people your age, go ahead and use intonation questions with the question word at the end:

With strangers, older people, or in professional settings, you'll want to use est-ce que or inversion:

Notice the switch from "tu" to "vous" too? That's part of the formality package.

Tricky bits that confuse learners

Tips to practice question words in French

The best way to get comfortable with French questions is to hear them in context.

It looks tricky and unnatural at first, but you'll get used to how to form a question

The more you expose yourself to real French, the more these patterns will stick. When you see these rules for the first time, they slip away from your brain fast like water running over a duck's feather. That's normal. Keep the grammar rules backstage, and immerse yourself in real content with no pressure. Reading helps too, especially dialogue in novels or comic books, where you see conversational French written out.

The best moment is when you can speak without thinking about the rules!
