Saber and conocer can both be translated by the English verb “to know,” but they are used in completely different situations.
Saber means to know a fact or to know how to do something. It is often followed by an infinitive or a subordinate clause.
In the pretérito, saber means to learn or to find out:
Conocer means to know someone or to be familiar with someone, something, or somewhere. It can only be followed by a direct object, never by an infinitive or a subordinate clause.
Remember that if the direct object is a person, the personal preposition a must be used.
In the pretérito, conocer means to meet someone for the first time.
Now that you know how to know, take the Test on saber vs cononcer.
