Savoir is a French verb meaning “to know.” It is used to express knowledge of facts, information, or a learned skill. Savoir is irregular and is commonly followed by a subordinate clause introduced by que, si, or a question word (e.g., , comment), or by an infinitive.
  • Use savoir + que/si/wh-: Savoir is often followed by que (that), si (if/whether), or a question word (e.g., , comment).
  • Use savoir + infinitive: Savoir can be followed directly by an infinitive to mean “to know how to do something.”
  • Do not confuse with connaître: Savoir refers to knowing facts or how to do something, while connaître refers to being familiar with people, places, or things.

. Usage

Savoir is used to express:
  • Knowledge of facts or information
  • Knowing how to do something (a skill)
  • Understanding or being aware of something
Examples:
  • Je sais que tu viens ce soir. (I know that you’re coming tonight.)
  • Sais-tu où est la bibliothèque? (Do you know where the library is?)
  • Elle sait parler espagnol. (She knows how to speak Spanish.)
  • Nous savons nager. (We know how to swim.)

We know how to swim.


Nous savons nager.

The correct sentence uses savoir + infinitive: "Nous savons nager" means "We know how to swim." Connaître is incorrect, and the other options misuse the infinitive form.
