* "Is it true that..."
* "Do you..."
* "Are you..."
* "Does..."
* "Is..."
For example:
* Est-ce que tu parles français ? (Is it true that you speak French? / Do you speak French?)
* Est-ce que vous êtes fatigué ? (Is it true that you are tired? / Are you tired?)
* Est-ce que le train arrive à l'heure ? (Is it true that the train arrives on time? / Does the train arrive on time?)
* Est-ce que c'est bon ? (Is it true that it's good? / Is it good?)
You can also use "est-ce que" for yes/no questions.
* Est-ce que tu as faim ? (Are you hungry?)
* Est-ce que vous voulez du café ? (Do you want coffee?)
In informal speech, you can often omit "est-ce que" and simply use the verb in the interrogative form.
* Tu parles français ?
* Vous êtes fatigué ?
* Le train arrive à l'heure ?
However, using "est-ce que" can make the question sound more polite or formal.
