Saber vs. Conocer: Which to Use for To Know
The two Spanish verbs that both translate as to know. Saber covers facts, information, and how-to skills. Conocer covers people, places, and being familiar with something.
Sé cocinar. / Conozco a la chef.
I know how to cook. / I know the chef.
What it is
Spanish splits the English to know into two verbs. Saber covers facts, information, and skills (how to do something). Conocer covers people, places, and familiarity with anything. Pick the wrong one and the sentence either sounds off or shifts meaning entirely.
In Sé cocinar (I know how to cook), saber covers a learned skill. In Conozco a la chef (I know the chef), conocer covers knowing a person. Both translate as I know in English, but Spanish keeps them strictly separate.
How to spot it
If the object is a fact, piece of information, or how-to skill → saber. If it's a person, place, or something you've encountered / experienced → conocer.
- Sé la respuesta. — I know the answer. (fact → saber)
- Conozco a tu hermano. — I know your brother. (person → conocer)
- ¿Conoces Madrid? — Have you been to Madrid? (place → conocer)
Mix them up and the sentence either flips meaning or sounds wrong. Native speakers don't run this check, they've heard the split thousands of times.

Common Saber vs. Conocer Examples in Spanish
Side-by-side examples make the split clear. Each row shows the same situation handled by saber or conocer.
Knowing Information vs. Knowing People
- Sé el número de teléfono.
- I know the phone number.
- Conozco a la persona.
- I know the person.
- Sé dónde vive.
- I know where he lives.
- Conozco su casa.
- I know his house.
Information (fact about where) → saber. Place itself (house, neighborhood) → conocer.
Knowing How vs. Being Familiar With
- Sé tocar guitarra.
- I know how to play guitar.
- Conozco una banda excelente.
- I know an excellent band.
- Sé conducir.
- I know how to drive.
- Conozco las calles de Madrid.
- I know the streets of Madrid.
Skill (you can do it) → saber + infinitive. Familiarity (you've experienced it) → conocer.
Preterite Meaning Shifts
- Supe la noticia ayer.
- I found out the news yesterday.
- Conocí a mi esposa en 2018.
- I met my wife in 2018.
- Supieron la verdad.
- They found out the truth.
- Lo conocí en una fiesta.
- I met him at a party.
Preterite shifts both verbs: supe = found out (came to know). conocí = met for the first time (came to know a person).
Tricky Cases
- Sé qué es.
- I know what it is.
- Conozco lo que es.
- I'm familiar with what it is. (rarer; nuance)
- Sé esa canción.
- I know that song (the words / facts).
- Conozco esa canción.
- I know that song (have heard it).
Sometimes both work but with different nuance. Sé focuses on facts; conozco focuses on familiarity.
How to Choose Between Saber and Conocer
Saber = Facts, Information, How-To Skills
Use saber when the object is a fact, a piece of information, a date / time, or how to do something (saber + infinitive).
Sé la respuesta. Sé que llegaste tarde. Sé cocinar.
I know the answer. I know you arrived late. I know how to cook.
If you can rephrase as I have the information that... or I have the skill to..., use saber.
Conocer = People, Places, Familiarity
Use conocer when the object is a person, a place, or something you've encountered / experienced (a brand, a song, a book).
Conozco a María. Conozco Barcelona. Conozco esa banda.
I know María. I know Barcelona. I know that band.
If you can rephrase as I'm familiar with..., use conocer.
Personal A Required Before People
Conocer takes personal a before a person as direct object: Conozco a Juan. No personal a before places: Conozco Madrid.
Conozco a Pedro. ≠ Conozco Pedro. (Wrong without personal a.)
I know Pedro. (Personal a is mandatory.)
If the object is a specific person, the a is required. Drop it for places or things.
Preterite Meanings Shift
In preterite, saber → found out (came to know information). Conocer → met for the first time (came to know a person). Both refer to the moment of discovery, not ongoing knowledge.
Supe que vienes. Conocí a tu padre.
I found out you're coming. I met your father (for the first time).
Ongoing past knowledge uses imperfect: sabía / conocía. Specific moment of discovery uses preterite: supe / conocí.
Common Mistakes with Saber vs. Conocer
Incorrect: Sé a María. — I know María. (wrong, people require conocer, not saber)
Correct: Conozco a María. — I know María.
People take conocer. Saber is for facts and information. Sé a María isn't grammatical.
Incorrect: Conozco la respuesta. — I know the answer. (wrong, facts require saber)
Correct: Sé la respuesta. — I know the answer.
An answer is a fact / piece of information, saber territory. Conocer would imply familiarity with the answer as a thing, not actually knowing it.
Incorrect: Conocí la noticia ayer. — I found out the news yesterday. (wrong, finding out info = supe)
Correct: Supe la noticia ayer. — I found out the news yesterday.
News is information → saber. Preterite supe specifically means found out. Conocí is for meeting a person.
Preterite Meaning Shifts
Saber → Supe (Found Out)
In the preterite, saber means to find out or to discover. It refers to the moment information arrived, not ongoing knowledge.
- Supe que tu hermana se casó.
- I found out your sister got married.
- Cuando supimos, ya era tarde.
- When we found out, it was already too late.
Imperfect sabía = had been knowing (ongoing). Preterite supe = found out (one-shot moment).
Conocer → Conocí (Met for First Time)
In the preterite, conocer means to meet someone for the first time. It refers to the moment of introduction.
- Conocí a mi esposo en la universidad.
- I met my husband in college.
- ¿Cuándo conociste a Pedro?
- When did you meet Pedro?
Imperfect conocía = had been knowing / was familiar with. Preterite conocí = met (first time).
Saber vs. Conocer FAQs
- What's the difference between saber and conocer in Spanish?
- Saber means to know facts, information, or how to do something. Conocer means to know people, places, or be familiar with something. Sé la respuesta (I know the answer) uses saber; Conozco a María (I know María) uses conocer.
- When do I use saber vs. conocer?
- Use saber for facts (Sé tu número), how-to skills (Sé nadar), and information (Sé que viene). Use conocer for people (Conozco a Ana), places (Conozco Roma), and things you've encountered (Conozco esa canción).
- What happens to saber and conocer in the preterite?
- Both shift meaning. Supe (preterite of saber) = found out / discovered. Conocí (preterite of conocer) = met for the first time. Imperfect forms (sabía, conocía) keep the ongoing know meaning.
- Do I need personal a with conocer?
