Saber vs Conocer: Two Ways to 'Know' in Spanish

English has one verb for knowing: know. Spanish has two — saber and conocer — and they’re not interchangeable.

The core distinction: saber is for knowing facts and how to do things. Conocer is for being acquainted with people, places, and things.

When to Use Saber

Knowing Facts and Information

Use saber when you know a piece of information — something you could state or recall:

• No sé la respuesta. — I don’t know the answer.
• Sabes su número de teléfono? — Do you know his phone number?
• Sé que mañana hay examen. — I know there’s an exam tomorrow.
• Ella sabe hablar cuatro idiomas. — She knows how to speak four languages.

Knowing How to Do Something

Saber + infinitive means “to know how to” — a learned skill or ability:

• Sé nadar. — I know how to swim.
• ¿Sabes cocinar? — Do you know how to cook?
• No saben bailar salsa. — They don’t know how to dance salsa.
• Mi hijo ya sabe leer. — My son already knows how to read.

This is different from poder (to be able to) — saber implies you’ve learned a skill, poder implies you have the opportunity or physical capability in the moment.

Knowing a Fact Inside a Clause

When “know” is followed by a that-clause, question word, or if:

• Sé que tienes razón. — I know (that) you’re right.
• No sé cuándo llega. — I don’t know when she’s arriving.
• ¿Sabes dónde está el banco? — Do you know where the bank is?
• No sé si viene o no. — I don’t know if he’s coming or not.

When to Use Conocer

Knowing People

Use conocer for being acquainted with a person — you’ve met them:

• ¿Conoces a María? — Do you know María?
• Conozco al director del colegio.* — I know the school principal.
• No los conozco. — I don’t know them.

Note the personal a before direct objects that are people: conocer a alguien.

Knowing Places

Conocer is used for knowing a place — meaning you’ve been there and are familiar with it:

• ¿Conoces Madrid? — Do you know Madrid? (Have you been there? Are you familiar with it?)
• No conozco bien este barrio. — I don’t know this neighborhood well.
• Conozco una buena restaurante por aquí. — I know a good restaurant around here.

Being Familiar With Things

Conocer also applies to works, concepts, or things you’ve experienced:

• ¿Conoces esta canción? — Do you know this song? (Are you familiar with it?)
• Quiero que conozcas mi trabajo. — I want you to see (know / be familiar with) my work.
• No conozco bien la obra de Cervantes. — I’m not very familiar with Cervantes’s work.

The Preterite Twist

In the preterite tense, both verbs shift meaning:

Verb	Imperfect	Preterite
saber	knew (ongoing state)	found out (the moment of learning)
conocer	was acquainted with	met (for the first time)

• Sabía que venía. — I knew he was coming. (I already knew)
• Supe que venía cuando llamó. — I found out he was coming when he called. (in that moment)
• Conocía a Juan. — I knew Juan. (I was acquainted with him)
• Conocí a Juan en la fiesta. — I met Juan at the party. (for the first time)

This is one of the most elegant examples of how the preterite/imperfect distinction changes meaning.
