What are Causal Clauses?
Causal clauses are dependent clauses that explain the reason or cause behind an action or state. In French, they use conjunctions like parce que, puisque, comme, and vu que to link a reason to a result.
Causal clauses are subordinate clauses that introduce the reason or cause for something. They use French conjunctions (parce que, puisque, comme, vu que) to explain why something happens.
- •parce que — because (most common)
- •puisque — since (reason already known)
- •comme — since, as (gives a reason)
- •vu que — given that, seeing that
- •Je reste à la maison parce qu'il pleut.
- •Puisque tu arrives demain, je préparerai le dîner.
- •Comme tu aimes la musique, voici ce disque.
- •Vu que c'est tard, allons-nous coucher.

Common mistakes
Using parce que and puisque interchangeably without considering context. — Correct: Use parce que for new reasons, puisque when the reason is already established.
Thinking causal clauses must always follow the main clause. — Correct: Causal clauses can come before or after: Parce qu'il pleut, je reste. = Je reste parce qu'il pleut.
Forgetting to use the subjunctive mood after causal clauses. — Correct: Causal clauses use the indicative (not subjunctive) because they state a fact, not a doubt.
Confusing causal clauses with temporal clauses. — Correct: Causal = why (reason), Temporal = when (time). Different conjunctions and purposes.
FAQ
What is a causal clause?
A causal clause is a dependent clause that explains why something happens, introduced by conjunctions like parce que, puisque, comme, or vu que.
Quand utilise-t-on parce que vs puisque?
Parce que introduces a new reason. Puisque is used when the reason is already known or accepted by both the speaker and listener.
Can you place a causal clause at the beginning of a sentence?
Yes. Example: Parce qu'il pleut, je ne sors pas. (Because it's raining, I'm not going out.)
Do causal clauses use subjunctive or indicative?
They use the indicative mood because they state facts and reasons, not doubts or hypotheticals.
