Future temporal clauses (quand, dès que)

Future Temporal Clauses

In English, when we talk about a future event using words like "when" or "as soon as", the first verb is usually in the present tense: "When they demonstrate, they will win."

In French, if the action in the temporal clause happens in the future, it must use the future tense (le futur simple). You will use the future tense in both halves of the sentence.

When the workers demonstrate, they will go down into the street.
Quand les travailleurs manifesteront, ils descendront dans la rue.
When you organize the protest, you will not do it without me.
Quand vous organiserez la manifestation, vous ne la ferez pas sans moi.

Dès que (As soon as)

The expression dès que means "as soon as". Just like quand, it requires the future tense for upcoming events.

As soon as the union announces it, the strike will begin.
Dès que le syndicat l'annoncera, la grève commencera.
As soon as the negotiation begins, they will answer the workers.
Dès que la négociation commencera, ils répondront aux travailleurs.

Lorsque vs. Quand

Lorsque is another word for "when". It means the same thing as quand and follows the same future-tense rule, but it is slightly more formal.

(Note: Unlike *quand, lorsque is only used to connect statements. You cannot use it to ask a question.)*

When the union obtains its demands, the strike will end.
Lorsque le syndicat obtiendra ses revendications, la grève finira.
When the minister hears our demand, he will accept.
Lorsque le ministre entendra notre revendication, il acceptera.
