Expression de la cause: How to explain "why".
When you want to justify an action, explain a situation, or give a reason in French, you have several tools at your disposal. Choosing the right connector depends entirely on two things: whether the reason is a full sentence or just a single noun, and whether the listener already knows the reason you are giving.
1. Explaining the Unknown: « Parce que » vs « À cause de »
When the reason or cause provides new or unknown information to the listener, you will typically use one of these two phrases. Your choice depends strictly on grammar:
« Parce que + phrase (Subject + Verb) » (Because...)
- Use this to connect to a full clause. It becomes parce qu' before a vowel.
- « Il joue mal parce qu'il est fatigué. » (He plays poorly because he is tired.)
« À cause de + nom (Noun) » (Because of... / Due to...)
- Use this when your reason is just a noun or noun phrase. It usually implies a negative or neutral cause.
- « Il joue mal à cause de sa fatigue. » (He plays poorly because of his fatigue.)
2. Highlighting the Obvious: « Comme » and « Puisque »
When the reason or cause is already known, obvious, or evident to everyone involved, French shifts to a different set of connectors.
« Comme / Puisque + phrase (Subject + Verb) » (Since... / As...)
- Comme is specifically placed at the very beginning of the sentence to launch the reason before the result.
- « Comme il est fatigué, il joue mal. » (As/Since he is tired, he plays poorly.)
- Note: Puisque functions identically in meaning (puisqu'il est fatigué...) but carries an extra tone of "since it's an obvious fact."
➔ Need to follow up with a noun? Use à cause de.
➔ Explaining a new reason with a full clause? Use parce que in the middle of the sentence.
➔ Starting your sentence with the reason first? Lead with Comme!
