Quick answer
Use savoir for facts and skills: je sais nager, je sais qu’il vient. Use connaître for people, places and things you are familiar with: je connais Paul, je connais Lyon. Savoir is followed by a verb or a clause; connaître by a noun.
English has one verb for all of this: “to know”. French has two, and mixing them up is a very common mistake for English speakers. The good news is that one simple rule covers most cases.
The core rule: facts and skills vs familiarity
Savoir: you know a fact, or you know how to do something
- A fact or a piece of information: Je sais que Paris est la capitale de la France.
- An answer to where, how, why, when or who: Je sais où elle habite.
- A skill you have learned: Je sais nager.
Connaître: you are familiar with someone or something
- A person you have met: Je connais Paul.
- A place you have been to or know well: Je connais Lyon.
- A thing you have come across, such as a song, a film, a book or a restaurant: Je connais cette chanson.
The idea behind it: savoir is about knowledge in your head, facts and know-how. Connaître is about acquaintance: you have met, seen or experienced the person, the place or the thing. That is why you can know who someone is without knowing them: Je sais qui est Marie, mais je ne la connais pas.
The quick test
Look at what comes after the verb. A verb or que / si / où / comment / pourquoi? Savoir. A noun, a name, or le / la / les? Connaître.
If you know Spanish or German, you already know this split: saber / conocer in Spanish and wissen / kennen in German work in a very similar way.
Savoir vs connaître: comparison table
| Savoir | Connaître | |
|---|---|---|
| Core idea | To know a fact, or to know how to do something | To be familiar with a person, a place or a thing |
| Followed by | A verb in the infinitive, or que, si, où, comment, pourquoi, quand, qui + a clause | A noun, or a pronoun that stands for one (le, la, les) |
| Typical objects | Facts, answers, reasons, skills | People, places, books, films, songs, restaurants |
| Example | Je sais nager. Je sais où il habite. | Je connais Paul. Je connais Lyon. |
| With a person | Only a fact about them: Je sais qui c’est. | The person themselves: Je connais ma voisine. |
| On its own | Je sais. (I know.) Fine on its own. | Needs an object: Je le connais. (I know him.) |
| Present: je / nous | je sais / nous savons | je connais / nous connaissons |
| Past participle | su (j’ai su) | connu (j’ai connu) |
| Passé composé means… | found out, learned | met, got to know; lived through |
| Imparfait | je savais = I knew (a fact) | je connaissais = I knew (was familiar with) |
Both verbs are irregular, both take avoir in the passé composé, and both are among the 200 most common French verbs.

| 19 | Elle connaît tous les films de Truffaut. | She knows all of Truffaut’s films. | Familiarity with works. |

| 22 | Je connais Paris, mais je ne sais pas où se trouve ce musée. | I know Paris, but I don’t know where this museum is. | Paris = connaître. où + clause = savoir. |
| 23 | Je connais cette chanson, mais je ne sais pas la chanter. | I know this song, but I can’t sing it. | The song = connaître. Singing it = a skill = savoir. |
| 24 | Tu connais Julie ? Tu sais où elle habite ? | Do you know Julie? Do you know where she lives? | Same pair of questions. |
Say it like a native
- In speech, je sais sounds like “chais” and je sais pas becomes chais pas. You will hear it all the time. Write the full je ne sais pas.
- Tu sais and il sait sound exactly the same, and so do tu connais and il connaît. Only the spelling tells you the person.
- When you are not sure, check the next word. A person or a place never follows savoir directly: Je sais Paul is wrong, Je connais Paul is right.
The tricky cases
Savoir + que, si, où, comment…
When a clause follows, it is always savoir. The question words are the clue.
| Word | Meaning | Example |
|---|---|---|
| que | that | Je sais que tu es là. |
| si | whether | Je ne sais pas si elle viendra. |
| où | where | Tu sais où il est ? |
| comment | how | Il sait comment faire. |
| pourquoi | why | Je sais pourquoi. |
| quand | when | Je ne sais pas quand il arrive. |
| qui | who | Tu sais qui a appelé ? |
| ce que | what | Je sais ce que tu veux. |
Never use connaître here: Je connais où il habite is wrong. Say Je sais où il habite.
Connaître + a noun
Connaître always needs an object: a person, a place or a thing. It does not work with a verb or a clause. When the noun is really a piece of information (the answer, the truth, an address), both verbs are used: Tu connais la réponse ? and Tu sais la réponse ? are both fine. Savoir stresses the information, connaître stresses that you are familiar with it.
One idiom to learn: Je connais la chanson ! means “I’ve heard it all before!”
“Je sais pas” in speech
Spoken French drops the ne and squeezes the words together. The same goes for je connais pas.
| French | English |
|---|---|
| Je ne sais pas. | I don’t know. (full form, for writing and polite speech) |
| Je sais pas. | I don’t know. (everyday speech) |
| Chais pas. | I dunno. (fast, casual) |
| Je n’en sais rien. | I have no idea. |
Two more things you will hear: Tu sais as a filler (“you know”), and Je sais ! to agree (“I know!”).
Savoir or pouvoir?
Savoir + infinitive means you have learned how to do something. Pouvoir means you are able to, or allowed to, right now. The two can be in the same sentence. More in how to express modal verbs in French.
Je sais nager, mais je ne peux pas nager aujourd’hui : j’ai mal au bras.I know how to swim, but I can’t swim today: my arm hurts.
Reconnaître
Reconnaître means “to recognize” and also “to admit”. It is conjugated like connaître (je reconnais, il reconnaît, reconnu), but it is a different verb.
| French | English |
|---|---|
| Tu me reconnais ? | Do you recognize me? |
| Je ne te reconnais plus ! | I don’t recognize you anymore! (You have changed.) |
| Il faut reconnaître que tu as raison. | I have to admit that you’re right. |
Se connaître and s’y connaître
Se connaître means “to know each other”, and in the passé composé “to meet”: Ils se sont connus à l’université. The participle agrees (connus) because se stands for “each other”. S’y connaître en means “to be an expert in”.
| French | English |
|---|---|
| Vous vous connaissez ? | Do you know each other? |
| Ils se sont connus à l’université. | They met at university. |
| Elle s’y connaît en informatique. | She knows a lot about computers. |

In the passé composé: j’ai su, j’ai connu
The meaning changes in the passé composé, and this is where English speakers get surprised. J’ai su is not “I knew”. It is “I found out”. J’ai connu is not just “I knew”. It is “I met”, or “I knew (at that time)”, or “I lived through”. For a state in the past, use the imparfait.
| Tense | Savoir | Connaître |
|---|---|---|
| Imparfait | Je savais qu’elle partait. I knew she was leaving. | Je connaissais déjà ce restaurant. I already knew this restaurant. |
| Passé composé | Quand j’ai su qu’elle partait, j’ai pleuré. When I found out she was leaving, I cried. | J’ai connu ma femme à Lyon. I met my wife in Lyon. |
| French | English |
|---|---|
| Je savais qu’elle partait. | I knew she was leaving. |
| Quand j’ai su qu’elle partait, j’ai pleuré. | When I found out she was leaving, I cried. |
| Il n’a pas su répondre. | He wasn’t able to answer. (ne pas savoir in the passé composé = couldn’t, didn’t manage to) |
| Je connaissais déjà ce restaurant. | I already knew this restaurant. |
| J’ai connu ma femme à Lyon. | I met my wife in Lyon. |
| Mon grand-père a connu la guerre. | My grandfather lived through the war. |
| Je n’ai pas connu mon grand-père. | I never knew my grandfather. |
The full passé composé vs imparfait rules are in imparfait vs passé composé, and the whole system is in French past tense: everything you need to know.

FAQ
What is the difference between savoir and connaître?
Savoir is for facts and skills: you know something, or you know how to do it. Connaître is for being familiar with a person, a place or a thing. After savoir comes a verb or a clause (que, si, où, comment…); after connaître comes a noun.
Can you say “Je sais” and “Je connais” on their own?
Je sais works on its own: “I know.” Je connais needs an object, so you say Je le connais (I know him) or Je connais Paul.
How do you say “I know him” and “I know that” in French?
Je le connais for a person (“I know him”), and Je le sais or Je sais for a fact (“I know that / I know”).
Do you use savoir or pouvoir for “can”?
For a skill you have learned, savoir: Je sais nager. For being able or allowed to do something right now, pouvoir: Je peux venir demain.
How do you say “I don’t know” in French?
Je ne sais pas is the standard form. In speech: Je sais pas or Chais pas. Other ways: Je n’en sais rien (I have no idea) and Aucune idée.

Avoir. The passé composé is j’ai su and, for connaître, j’ai connu.
