The third group: comprises all the other verbs. We also call them “irregular verbs” because they don’t follow any specific conjugation. For example: prendre, tenir, voir, etc.
The verbs of the third group don’t follow any specific rule. That’s why we call them “verbes irréguliers” . Their conjugation varies depending on the verb. We will try to classify them according to their terminaisons or their racines.
