Quand (question word)

‘Quand’ means ‘when’ and is placed at the beginning of a time‑question.

2

est‑ce que (question‑forming particle)

‘est‑ce que’ turns a statement into a yes/no or wh‑question without changing word order.

✕Common Mistakes

  • Quand est‑ce que ça commencer ?

    The infinitive ‘commencer’ must be conjugated in the passé composé.

  • Quand est‑ce que ça a commencer ?

    The past participle needs the accent ‘é’ – ‘commencé’. Also, the auxiliary ‘a’ must be followed by the past participle.

  • Ça a commencé quand ?

    In French the question word stays at the front; placing ‘quand’ at the end creates a clumsy structure.

Cultural Tip

French speakers love the ‘est‑ce que’ construction for clarity, especially in spoken language. While ‘ça’ is perfectly natural in conversation, avoid it in formal writing; replace it with ‘cela’ or the noun you’re referring to. Also, note that the passé composé is the default past tense for completed actions, so ‘a commencé’ is the right choice here.
