You (formal) knew
NosotrosConociéramosWe knew
Ellos / Ellas

ConocieseHe/She knew

UstedNo conozcaDon’t meet
VosotrosNo conozcáisDon’t meet
UstedesNo conozcanDon’t meet

Meanings of Conocer & Examples

Since we’ve just learned how to conjugate conocer, here are some examples of how to apply this verb to your Spanish conversations.

  1. Talking about meeting/knowing someone 

(Object pronoun) + [conocer conjugated] + a + (noun)

Creo que no la conozco. ¿Cómo se llama?
I don’t think I know her. What’s her name?

En unos días, conoceremos a nuestros vecinos.
We will meet our neighbors in a few days.

Take Note: Use direct object pronouns in Spanish to replace the person someone knows. However, if you’re expressing that two people know each other, you should use reflexive pronouns to convey reciprocity. 

  1. Expressing your familiarity with a place 

[Conocer conjugated] + [determiner] + [noun]

¿Ya conocen este restaurante?
Do you guys already know this restaurant?

No conocía esta canción, es muy bonita.
I didn’t know this song; it’s very nice.

Take Note: Because they’re both translated as ‘to know’, conocer and the verb saber are usually confused. However, you should take the time to understand how saber vs conocer work
