PrÉpositions Avec Le temps POUR, DANS, et EN
Review • Depuis means "since" or "for." It is used with a French verb in the present tense to talk about an action that began in the past and continues in the present. • J'étudie le françaisdepuis 3 ans. I've studied French for 3 years (and still do). • Pendant means "for" and refers to the entire duration of an action in the past or future, with no relation to the present. • J'aiétudié le français pendant 3 ans. I studied French for 3 years (and then stopped).
review • Pendant followed by a noun means "during." In this sense, it is synonymous with durant. • J'ai vu un film pendant monséjour. I saw a film during my stay. • “Il y a” means "ago" and can only be used for things that are already completed. The verb in the sentence must be in the past and il y a must be followed by some reference to time. • Je suisarrivéeil y a uneheure. I arrived an hour ago.
POUR • Pourmeans for. It can express the duration of an event only in the future. Note that pendant could also be used in all of these.
exemples • Je vais y habiter pour 2 mois. I'm going to live there for 2 months. • Il étudiera en Europe pour 3 ans. He'll study in Europe for 3 years. • Le projetestsuspendu pour un an. The project is suspended for a year.
Be careful… • Although the verb in the final example is not in the future, the use of pour indicates that the one-year suspension is either about to start or is currently underway. If the suspension had already occurred, you would have to use pendant:Le projet a étésuspendu pendant un an. The project was suspended for a year.
dans • Dans means in. It is used to indicate a moment in the future in which something will occur.
exemples • Je partiraidansdeux ans. I will leave in two years. • Le film finiradansuneheure. The film will end in one hour.
en • En means in. It is used to indicate the amount of time needed to complete an action.
