Remember, question words like quand and pourquoi come before est‑ce que!
Pourquoi est‑ce que tu te réveilles tard ?
Whyare you waking up late?
Quand est‑ce que vous allez à Paris ?
Whenare you going to Paris?
In English, we might say Who are you going outwith? But in French, avec always comes before qui!
Avec qui est‑ce que tu sors ?
With whom are you going out?
Qui est prêt ?
When not talking about a specific person or thing, French speakers default to using the masculine form of a word. The feminine form is used when talking specifically about feminine things or people.
