Explaining causes, results, and purpose in French

In English, “because of” comes before a noun and “because” introduces a clause. French makes a similar distinction: use “à cause de” with a noun group and “parce que” with a clause. This lesson also shows how “alors,” “pour,” and “pour que” express consequences and purposes.

Words for causes and purpose

“À cause de” means “because of,” “pour” can mean “in order to,” and “pour que” means “so that.” The construction after each one matters: a noun group follows “à cause de,” an infinitive follows “pour” for a purpose, and a clause with the subjunctive follows “pour que.”

Give a cause with a noun

Use “à cause de” before a noun group: “à cause de la neige.” Use “parce que” before a clause with a subject and verb. This parallels standard English “because of” versus “because.” “À cause de” commonly introduces the cause of an unwanted situation. The first example uses “nous,” which is more formal than conversational “on” meaning “we” in the second example.

Connect a cause to what happened next

After the situation and its cause, use a consequence connector such as “alors” or informal “du coup” to say what actually followed. “La route était fermée à cause de la neige, alors nous avons pris le train” gives the cause and the real consequence. “Du coup” is conversational; “alors” is suitable in more neutral or formal speech. “On” commonly means “we” in informal French.

Give a purpose with an infinitive

Use “pour” followed by an infinitive to express a purpose, normally when the main action and the purpose have the same subject. “Pour gagner du temps” means “in order to save time”; no extra equivalent of “in order” is needed. “Nous” gives the first example a more formal tone, while “boulot” is an informal word for a job; “je” itself is neutral. The final example is also grammatically neutral and is used here in an informal conversation. It shows that a purpose can fail: the speaker wanted a seat, but the room was already full.

Give a purpose with “pour que”

Use “pour que” followed by a subject and a subjunctive verb, especially when the purpose has a different subject from the main action: “pour que tout le monde puisse suivre.” English similarly allows a clause with “so that,” but French requires the subjunctive after “pour que.” “Pourriez-vous” makes a polite request, with “vous” marking formal singular address or plural address; “Tu peux” addresses someone informally. In the map example, “puisse” remains in the present subjunctive even though the main action happened in the past. That sentence uses “nous” and is labelled formal here, although its purpose construction is usable in either register.

Separate an intended aim from the outcome

“Pour” and “pour que” state the aim, but do not say whether it succeeded. In “Je suis parti tôt pour avoir une place, mais la salle était déjà pleine,” the speaker left early hoping to get a seat, but the room was already full. The same contrast appears in “Nous lui avons envoyé un plan pour qu'elle puisse trouver le bureau, mais elle s'est quand même perdue.”

Ask why someone missed a talk

The dialogue is informal: it uses “tu,” “te,” and “t'as,” a very informal written representation of spoken “tu as.” “Pourquoi” asks the reason; “pour avoir une place” gives an intended purpose, followed by the actual outcome with “mais.” That purpose sentence is neutral in itself and fits this informal exchange. The request “Tu peux m'envoyer” is informal, and “pour que je puisse” takes the subjunctive. “Bien sûr” signals agreement, and “Je te les envoie ce soir” uses the present tense to promise to send the notes tonight.
