What this is
English has one verb for “know” and leans on context to sort out what kind of knowing you mean. French splits that job across two completely different verbs, and picking the wrong one doesn’t just sound slightly off — it produces a sentence that doesn’t parse. This concept teaches both verbs, plus a third: voir (to see), which you’ve been using informally since early in the course without ever seeing its full present-tense paradigm laid out. All three are irregular, and none of them follow the -er/-ir/-re patterns you already know.
The rule
| savoir | voir | connaître | |
|---|---|---|---|
| je | sais | vois | connais |
| tu | sais | vois | connais |
| il/elle/on | sait | voit | connaît |
| nous | savons | voyons | connaissons |
| vous | savez | voyez | connaissez |
| ils/elles | savent | voient | connaissent |
savoir is for facts, information, and skills — anything you could finish with “…that,” “…how,” or a question word. It takes a clause (je sais où elle habite — I know where she lives), an infinitive (je sais nager — I know how to swim), or a fact stated outright (je sais la vérité).
connaître is for familiarity with a person, a place, or a thing — anything you’d answer with “yes, I’ve met them” or “yes, I’ve been there.” It always takes a direct object — a noun phrase — and never a clause. This is the one rule worth memorizing above all the others here: if what follows the verb is a person or a place, reach for connaître; if it’s a fact, a clause, or “how to,” reach for savoir.
voir just means “to see,” and its paradigm is worth learning explicitly now because you’ve already been producing forms of it by ear (je vois, il voit) without the underlying pattern being named.
Why it works this way
The savoir/connaître split isn’t arbitrary — it tracks a real distinction French insists on marking that English doesn’t bother with. Knowing a fact is a different mental act from having encountered a person or place, and French gives each its own verb rather than letting one verb cover both, the way English does with the single, overworked “know.” Once you internalize the test — is what follows a person/place, or a fact/clause? — the choice stops being a vocabulary problem and becomes a grammar reflex.
Edge cases
connaître can never take a clause
This is the single most common mistake in this pair. Je sais où elle habite is correct — savoir happily takes the whole clause “where she lives.” But Je connais où elle habite does not work: connaître demands a direct object noun phrase, not a clause, so there is nothing for it to attach to here. If you’re tempted to follow connaître with “où,” “que,” “pourquoi,” or any other clause-starter, stop — you want savoir instead. The same logic explains Nous savons pourquoi tu pars (we know why you’re leaving): pourquoi introduces a clause, so it has to be savoir, regardless of how tempting “connaître” might feel with a more concrete-sounding subject.
The circumflex in connaît appears only before a written t
Look at the table again: connais, connais, connaissons, connaissez, connaissent all use a plain “ai.” Only the il/elle/on form — connaît — carries a circumflex, and it appears precisely because that form is the only one where the stem’s final vowel sits directly in front of a written “t” with nothing in between. The circumflex marks a letter (historically an “s”) that used to sit there and got dropped, leaving the accent behind as a trace. You’ll see the identical pattern on other verbs later (paraître → il paraît); for now, the rule to hold onto is mechanical: circumflex only immediately before a bare “t,” nowhere else in the paradigm.
What English speakers get wrong here
The most frequent error is reaching for connaître with a clause, because English “I know that…” feels like it should map onto whichever French verb comes to mind first. Train yourself to check what follows the verb before you conjugate: a noun phrase (a person, a place, a thing) means connaître; anything with the shape of a clause — a question word, “que,” or a bare infinitive — means savoir.
The second is dropping the circumflex or adding it where it doesn’t belong — writing “connais” as “connaît” out of over-caution, or leaving it off “il connaît.” The rule is narrow enough to just memorize: the accent lives only on the il/elle/on form, directly before the t.
The third is treating savoir + infinitive as needing a preposition, by analogy with English “know how to.” French doesn’t insert one: je sais nager, not “je sais de nager” or “je sais à nager” — the infinitive attaches directly, the same way it does after pouvoir, vouloir, and devoir.
