parce

In a sentence

• Je suis resté à la maison parce qu'il pleuvait.

  I stayed at home because it was raining.

  Used as part of the conjunction 'parce que,' which introduces a reason or cause.

• Elle est heureuse parce qu'elle a réussi son examen.

  She is happy because she passed her exam.

  Again, 'parce que' connects the cause (passing the exam) to the effect (feeling happy).

• Parce que c'est important, nous devons en discuter.

  Because it is important, we need to discuss it.

  Here, 'parce que' begins the sentence to emphasize the reason, maintaining its role as a causal connector.
