A few quick notes about savoir

Savoir is an irregular ir verb. This means that its endings in the present tense are different to other regular -ir verbs, such as finir (to finish).

In this post we’ve covered the following major tenses:

  • present (le présent)
  • passé composé (compound past)
  • imperfect (l’imparfait)
  • future (le futur simple)
  • conditional (le conditionnel)
  • subjunctive (le subjonctif)

The past participle of savoir is su (knew, found out) and the present participle is savant (knowing).

Savoir means “to know” in the context of knowing facts. For example, je sais que le ciel est bleu (I know the sky is blue).
