Questions & Answers about Le train arrive enfin à Lille.
French verb endings work differently from English ones.
The verb here is arriver = to arrive. With le train (it), the present-tense form is:
- j’arrive
- tu arrives
- il / elle / on arrive
- nous arrivons
- vous arrivez
- ils / elles arrivent
So le train arrive is correct because le train is third-person singular, like it arrives.
Even though tu arrives and ils arrivent have extra letters in writing, those endings are often not pronounced differently.
