Savoir vs Connaître: When to Use Each in French

Savoir and connaître both mean “to know,” but French uses them for different kinds of knowledge. Do you know someone’s name? Know how to swim? Know Paris because you’ve spent time there?

English uses the same verb for all three. French makes a distinction, and fortunately, there’s a useful way to tell them apart.

✦The Question✦

What kind of knowledge are you talking about?

Savoir is knowing information, facts, or how to do something.
Connaître is being familiar with a person, place, subject, or thing.

1. When to Use SAVOIR

Use savoir when you know a fact, have information, or know how to do something.

Facts and Information

Savoir commonly introduces information through words like que (that), où (where), quand (when), pourquoi (why), comment (how), qui (who), and si (whether).

Je sais qu’elle habite à Paris. I know that she lives in Paris. savoir + que — a fact

Tu sais où est la gare ? Do you know where the station is? savoir + où — a location

Nous savons pourquoi il est parti. We know why he left. savoir + pourquoi — a reason

Tu sais si Julie vient ce soir ? Do you know if Julie is coming tonight? savoir + si — whether

The important thing is that you know some information you could explain or tell someone else.

Knowing How to Do Something

Savoir also expresses skills and abilities you’ve learned. Simply follow it with an infinitive:

Je sais nager. I know how to swim. savoir + infinitive

Elle sait jouer du piano. She knows how to play the piano. savoir + infinitive

Tu sais conduire ? Do you know how to drive? savoir + infinitive

Notice that French doesn’t need a separate word for “how” in these expressions. Savoir + infinitive already means “to know how to.”

✦Quick Clue✦

If “know” is followed by a whole clause (I know that…, I know where…) or an infinitive (I know how to swim), French uses savoir. This is one of the most reliable clues for choosing between the two verbs.

2. When to Use CONNAÎTRE

Connaître expresses familiarity with a person, place, subject, or thing. Rather than knowing a particular fact, you’re acquainted with what you’re talking about.

People

Use connaître when you know someone personally, or recognize them even if you’ve never met.

Tu connais Marie ? Do you know Marie? connaître — a person

Je connais bien ton frère. I know your brother well. connaître — personal familiarity

Je connais cette actrice de nom. I know this actress by name. connaître — familiarity through reputation

Places and Things

Use connaître when you’re familiar with a place, subject, or thing.

Je connais bien Lyon. I know Lyon well. connaître — a city

Nous connaissons un bon restaurant dans ce quartier. We know a good restaurant in this neighborhood. connaître — a place

Elle connaît bien l’histoire de France. She knows French history well. connaître — a subject

And when you know a place really well, French has a handy expression:

Elle connaît Paris comme sa poche. She knows Paris like the back of her hand. connaître comme sa poche

Unlike savoir, connaître is followed directly by a noun or noun phrase, never by a whole clause or an infinitive.

3. Same Subject, Different Kind of Knowing

Sometimes the easiest way to understand the distinction is to compare two sentences about the same person or place.

Je sais qui est Marie. I know who Marie is. savoir — her identity

Je connais Marie. I know Marie. connaître — familiar with her

Je sais où se trouve Lyon. I know where Lyon is. savoir — its location

Je connais Lyon. I know Lyon. connaître — familiar with the city

In the first pair, you either know a fact about Marie or you know Marie herself. In the second, you could know exactly where Lyon is on a map without ever having visited it, or know the city well because you’ve spent years there.

4. When Both Are Possible

With a few nouns that name a piece of information, both verbs are correct:

Je sais la réponse. I know the answer. savoir — correct

Je connais la réponse. I know the answer. connaître — also correct

The same goes for an address (une adresse) or a phone number (un numéro de téléphone). Neither verb is wrong in these situations.

5. Savoir and Connaître in the Past

In the imparfait, both verbs simply mean “knew,” with the same split as in the present:

Je ne savais pas qu’elle était mariée. I didn’t know she was married. savais — knew

Je connaissais tout le monde dans le village. I knew everyone in the village. connaissais — knew

In the passé composé, though, they can take on slightly different meanings. Savoir can mean “found out,” and connaître can mean “met” or “got to know”:

J’ai su la vérité hier. I found out the truth yesterday. j’ai su — found out

J’ai connu Paul à l’université. I met Paul at university. j’ai connu — met

These meanings depend on context, so don’t assume every passé composé use has to mean “found out” or “met.”

And that’s the distinction: savoir is about information and skills, while connaître is about familiarity with people, places, and things. The Savoir vs. Connaître deck will help you recognize which kind of knowledge you’re expressing until the choice starts to feel natural.
