Saber vs Conocer: Which 'to Know' You Need, With Examples, a Chart and a Quick Quiz

Why ¿Conoces Valencia? asks whether you have been there, why it is sé nadar and not puedo nadar, and the one test that picks the right verb before you open your mouth.

A dinner in Valencia, eight people around a table, and someone turns to you with ¿Conoces Alicante? You reach for a fact: it is down the coast, it has an airport, you know where it is. The question was never about that. Conocer a city means you have been there, walked it, have an opinion about it. The answer they were waiting for is sí, estuve en mayo (yes, I was there in May) or no, todavía no (not yet).

English gets by with one know. Spanish has two, and the line between them is not where English speakers expect it; the French and Germans at that same table never had the problem, because savoir / connaître and wissen / kennen map straight across. For everyone else: one test, two bullets, below.

The test: could you text it, or would you recognize it?

Forget "facts versus people", which is the version most courses teach and which breaks the first time you meet conocer la ciudad or saber de fútbol. Use this instead:

• Saber is anything you could write in a WhatsApp message: a fact, an answer, an address, a phone number, a skill you have. Sé dónde está la parada (I know where the stop is). Sé su número (I know her number). Sé conducir (I can drive).
• Conocer is anything you would recognize if it walked past you in the street: a person, a place, a song, a book, a bar, a neighborhood. Conozco a tu casera (I know your landlady). Conozco Ruzafa (I know Ruzafa, the neighborhood). Conozco esa canción (I know that song).

Try it on the dinner question. Alicante is not a fact you can text; it is a place you would recognize once you have been there.

So conocer.

Now tu vecina, your neighbor: you would recognize her at the mailboxes, which puts her on the conocer side too, while her phone number stays with saber.

The test survives the tricky cases too. Sé el camino and conozco el camino both exist. The first means you could describe the route; the second means you have walked it. Spaniards say the second when they want to reassure you: tranquilo, conozco el camino (relax, I know the way).

Saber: facts, answers and things you can do

Saber takes a fact, usually wrapped in que, si, dónde, cuánto or a bare noun: Sé que el bar abre a las siete (I know the bar opens at seven). No sé si hay huelga mañana (I don't know whether there is a strike tomorrow). ¿Sabes cuánto cuesta el abono? (do you know how much the pass costs?) The abono is the monthly transport pass (in Valencia, the SUMA Mensual), and that question will come up in your first week.

It is also the verb for skills. English says "I can swim"; Spanish says sé nadar, I know how to swim. Poder is for whether circumstances allow it right now: sé nadar, pero hoy no puedo, el agua está helada (I can swim, but not today, the water is freezing). The same goes for languages. ¿Sabes valenciano? means "can you speak it", and the answer is un poco, not a list of grammar rules you once read.

The only irregular forms in the present tense are the first persons, yo sé and yo conozco. One side effect worth knowing: sé is also the imperative of ser, so ¡sé bueno! is "be good", not "I know good". Context sorts it out. Both sé carry the accent mark, and the note from your casera has the imperative one: ¡sé puntual!, be on time.

Then there is the lo. English answers "I know" with two words; Spanish needs three. ¿Sabes que la farmacia de la esquina cierra en agosto? (did you know the pharmacy on the corner closes in August?) — Ya lo sé (I know). That lo stands in for the whole fact, the same neuter pronoun we took apart in lo, la, le or se. Dropping it (ya sé) is not wrong, but ya lo sé is what you will hear.

Conocer: anything you have met

Conocer takes a person, a place or a thing you have met. With a person it needs the personal a: conozco a Marta, ¿conoces a mi casero? (do you know my landlord?). Leave the a out and the sentence sounds like Marta is a brand of yogurt.

With a place it means "have been to" as much as "be familiar with". The bar on the corner counts. ¿Conoces el Mercado Central? asks whether you have walked under that roof, and no lo conozco is the honest answer until you have. With a book, a film or a song, conocer means you have come across it: conozco la canción, pero no me sé la letra, I know the song but I don't know the words.

That last sentence hides the pronominal saberse: saber plus a reflexive pronoun means to know something by heart, completely. Me sé la lección (I know the lesson by heart). Se sabe todas las calles del Carmen (she knows every street in El Carmen). Spaniards say it with a touch of pride, and turn it ironic for the person who se las sabe todas, who knows every trick in the book.

Spain adds two uses of its own. Conocerse, reciprocal, is how you tell the story of meeting someone: nos conocimos en una cena, we met at a dinner. And se conoce que, which has nothing to do with knowing anybody: it means "apparently", "it seems". The neighbor on the landing says it: se conoce que han vendido el bajo, apparently they have sold the ground-floor flat.

The cheat sheet

Saber de earns its row. Sé de vinos is "I know about wine"; no sé nada de ella is "I haven't heard from her". Both are saber, because both are information.

Where the past tense moves the line

In the pretérito indefinido both verbs shift meaning, and it catches people who have the present tense sorted. Sabía is "I knew"; supe is "I found out". Conocía is "I knew (someone)"; conocí is "I met". So ayer supe que hay huelga de Metrovalencia el lunes is "yesterday I found out there is a Metrovalencia strike on Monday", and conocí a mi casera en 2023 is "I met my landlady in 2023", not "I knew her".

We lined those pairs up in a table in indefinido vs imperfecto, next to quería and quise, and the logic is the same: the indefinido turns a state into the moment it began. This is also why the dinner-table answer to ¿conoces Alicante? is so often sí, la conocí el año pasado: I got to know it last year (la, because ciudad is feminine).

If ser and estar still fight each other in your head, learn the two pairs side by side: ser vs estar separates who you are from how you are, and the habit that fixes both is the same, stop translating and ask what kind of being, or knowing, it is.

One sentence to keep: if you could text it, saber; if you would recognize it, conocer.
