Questions & Answers about Nous devons valider nos billets avant de monter dans le train, et valider aussi ce formulaire sur Internet.
What does the verb valider mean in this context, especially since it is used with both tickets and an online form?
Why is the phrase avant de monter dans le train constructed with avant de followed by an infinitive?
In French, avant de is a standard construction used to indicate that one action takes place before another. It is always followed by an infinitive form (here, monter) because it expresses a condition in time: "before boarding the train."
Why is the verb valider repeated in the sentence without restating the subject?
It is common in French—and many languages—to repeat the main verb when listing multiple actions, even if the subject remains the same. The first clause gives the general obligation (Nous devons valider nos billets), and the second part continues the list of tasks (et valider aussi ce formulaire sur Internet). The subject "we" is understood for both actions, so repetition of the verb helps to emphasize and clearly structure each task.
What is the difference between nos billets and ce formulaire, and why are different determiners used?
