What is the difference between sapere and conoscere?

Sapere is knowing information or knowing how to do something: so che è vero, so guidare. Conoscere is being familiar with a person, a place, or a thing: conosco Luca, conosco Milano. Conoscere always needs a noun after it.

Which verb do I use with a person?

Conoscere if you have met them: conosco tuo fratello. Sapere only if you are identifying them in a clause: so chi è tuo fratello. The two sentences mean different things, and both can be true at once.

How do you say I can swim in Italian?

So nuotare. Sapere plus an infinitive describes a skill you have learned. Posso nuotare means the situation allows you to swim right now, which is a different idea.

Why does ho conosciuto mean I met?

Because the passato prossimo marks a completed event, and for a state verb like conoscere that event is the moment the acquaintance began. Ho saputo works the same way and means I found out.

Is it non so or non lo so?

Both are correct. Non lo so is the most common answer when someone asks you a question, because lo refers to the information they asked about. Non so is used before a clause: non so dove sia, I don't know where it is.

Sapere vs Conoscere

Written by Parrot Italian Team, Italian Curriculum Editors · Reviewed October 2026

Sapere and conoscere both translate as to know. Sapere is knowing information (a fact, an answer) and knowing how to do something. Conoscere is being familiar with a person, a place, or a thing. Conoscere always needs a noun after it, while sapere introduces a clause or an infinitive.

Conosco Roma, ma non so dov'è questa via.

I know Rome, but I don't know where this street is.

What it is

Use sapere for information and skills: so che hai ragione (I know you're right), so nuotare (I can swim). Use conoscere for people, places, and things you are familiar with: conosco tuo fratello (I know your brother), conosco Napoli (I know Naples). English uses know for both, but Italian keeps the two ideas apart.

So chi è, ma non lo conosco. (I know who he is, but I don't know him.)

How to spot it

Look at what follows the verb. A clause with che, se, dove, come, or perché, or an infinitive, means sapere. A person, a place, or another noun on its own usually means conoscere.

So che è partito. (I know he's left. (a clause))
Sai guidare? (Can you drive? (an infinitive))
Conosci mia sorella? (Do you know my sister? (a person))
Conosco bene questa zona. (I know this area well. (a place))

A few nouns of information, such as la risposta, la verità, and la strada, can go with either verb: so la risposta and conosco la risposta are both correct.

Common Sapere vs Conoscere Examples in Italian

Each pair puts the two verbs in the same kind of situation:

Facts vs People

So dove abita Paolo.: I know where Paolo lives.
Conosco Paolo da anni.: I've known Paolo for years.

Where Paolo lives is a piece of information, so sapere. Paolo himself is a person you know, so conoscere.

Skills vs Familiarity

So cucinare.: I can cook.
Conosco un ottimo ristorante.: I know a great restaurant.

Sapere plus an infinitive is a skill you have learned. A restaurant is a place you are familiar with.

Places

Sai dov'è la stazione?: Do you know where the station is?
Conosci Napoli?: Do you know Naples?

Conosci Napoli asks whether you have been there and know your way around. Sai dov'è asks for one piece of information.

Answers vs Works

Non so perché è arrabbiata.: I don't know why she's angry.
Non conosco questa canzone.: I don't know this song.

A reason is information. A song, a book, or a film is something you are familiar with.

Finding Out vs Meeting

Ho saputo la notizia stamattina.: I heard the news this morning.
Ho conosciuto Anna a Roma.: I met Anna in Rome.

In the passato prossimo, sapere means to find out and conoscere means to meet for the first time.

The Rules That Separate Them

One structural test settles most cases. The rest are about meaning.

Conoscere Always Takes a Direct Object

Conoscere needs a noun or a pronoun after it: a person, a place, a book, a subject. It cannot introduce a clause. If there is no noun for it to take, the verb you want is sapere.

Conosco la ricetta, ma non so farla.

I know the recipe, but I can't make it.

No noun after it: sapere.

Sapere Introduces Information

Che, se, dove, quando, come, perché, chi, and quanto all follow sapere. The verb holds a piece of information rather than describing familiarity with something.

Sai quando arriva il treno?

Do you know when the train arrives?

Question word next: sapere.

Sapere Plus an Infinitive Is a Learned Skill

English uses can for ability and for possibility. Italian uses sapere for a skill you have learned and potere for whether the situation allows it.

So nuotare, ma oggi non posso.

I can swim, but I can't today.

sapere = learned. potere = possible.

Non Lo So Needs the Pronoun

Italian usually adds lo to sapere when the information has already been mentioned. Non lo so is the normal way to say I don't know, and lo so is I know.

Dov'è Marco? Non lo so.

Where's Marco? I don't know.

Lo so. Non lo so.

Sapere Is Irregular, Conoscere Is Regular

Sapere has a short, irregular present: so, sai, sa, sappiamo, sapete, sanno. Conoscere is regular, but its sound changes: conosco and conoscono have a hard sc sound (as in sk), while conosci and conosce have the soft sh sound.

Sappiamo che conoscete bene la città.

We know that you know the city well.

so, sai, sa.

Common Mistakes with Sapere vs Conoscere

Incorrect: Conosco che hai ragione. (I know you're right.)

Correct: So che hai ragione. (I know you're right.)

Conoscere cannot introduce a clause. Anything introduced by che, se, or a question word goes with sapere.

Incorrect: So Maria. (I know Maria.)

Correct: Conosco Maria. (I know Maria.)

Knowing a person takes conoscere. Sapere with a person only works inside a clause: so chi è Maria.

Incorrect: Conosco nuotare. (I can swim.)

Correct: So nuotare. (I can swim.)

A skill expressed with an infinitive always takes sapere. Conoscere is only followed by a noun or a pronoun.

Incorrect: Non so questa città. (I don't know this city.)

Correct: Non conosco questa città. (I don't know this city.)

A place is something you are familiar with, so it takes conoscere. With sapere you need a clause: non so dov'è.

Edge Cases Worth Knowing

Both verbs describe states, so the past tense you choose changes the meaning.

How the past tenses change the meaning

In the imperfetto, both verbs keep their normal meaning. In the passato prossimo, they mark the moment the knowledge or the acquaintance began.

Sapevo che eri qui.: I knew you were here.
Ho saputo che eri qui.: I found out you were here.
Conoscevo già Marco.: I already knew Marco.
Ho conosciuto Marco ieri.: I met Marco yesterday.

Ho conosciuto is the normal way to say I met someone for the first time. For meeting up with a friend, use incontrare or vedersi.

Conoscersi and set phrases

The reflexive conoscersi means to meet each other or to know each other. Several everyday phrases use it.

Ci siamo conosciuti all'università.: We met at university.
Piacere di conoscerti.: Nice to meet you.
Vi conoscete?: Do you two know each other?

To someone you address formally, say piacere di conoscerLa, or simply piacere.

Sapere di: to taste of

Sapere di plus a noun means to taste of something. It has nothing to do with knowledge.

Questa torta sa di limone.: This cake tastes of lemon.
Questo vino sa di tappo.: This wine is corked.

The conditional non saprei (I wouldn't know) is a polite way to say you are not sure.
