Updated December 2, 2025 — Lesson written by French teacher David Issokson for students who want to learn French online, with native audio by Marie Assel Cambier, a voice artist from France.
The verb savoir (to know) is one of the top 10 most used irregular verbs in the French language. It is critical to master its forms and conjugations for two main reasons:
- Core Irregular Verb: It is a highly irregular verb that must be fully memorized by every beginner, as its forms (e.g., je sais, nous savons) do not follow standard patterns.
- Structural Function: It is the required verb for expressing how to do something (followed by an infinitive) and for knowing facts, information, or knowledge (followed by a clause).
