Imparfait versus Passé Composé

In addition to le passé composé (perfect or compound past tense), you can also use l'imparfait (imperfect tense) to talk about things that occurred in the past. So, when should you choose l'imparfait over le passé composé? Let's explore both tenses.

Before we embark on the specific uses of l'imparfait, let's find out how to form this past tense. Just take the nous (we) form of the present tense, as in nous faisons (we do/are doing), remove the -ons, and add the ending -ais, -ais, -ait, -ions, -iez, or -aient. So, nous faisons (we do/are doing) becomes nous faisions (we were doing/used to do). Margaux and Manon will show you how to conjugate the rest of the verb faire in the imparfait:

Je faisais... Tu faisais. Il ou elle faisait.

I was doing... You were doing. He or she was doing.

Nous faisions. Vous faisiez.

We were doing. You [pl. or formal] were doing.

Ils ou elles faisaient.

They [masc.] or they [fem.] were doing.

Now that you know how to form the imperfect tense, let's discuss how to use it. Usually, l'imparfait indicates ongoing actions in the past that have a stronger connection to the present than le passé composé, which describes a completed action. In his conversation with Lea in the video below, Lionel uses the imperfect form tu me parlais (you were telling me) as a subtle cue that he wants to hear more about the animals in the park. It's an invitation to Lea to elaborate:

Tu me parlais aussi tout à l'heure de la

You were also telling me earlier about the

présence d'animaux dans ces parcs.

presence of animals in these parks.

If Lionel wanted to say something like “you already told me earlier” and then changed the subject, he would have used passé composé:

Ah oui, tu m’en as déjà parlé tout à l’heure.

Oh yes, you already told me about that earlier.

But l'imparfait is not only used to evoke an ongoing action drifting into the present. It's also the ideal tense for talking about things you used to do or describing repeated actions. In the following video, Claire remembers how elle allait (she used to go) to the park with her daughter:

Oh,  j'y allais beaucoup avec ma fille, il y a quelques années.

Oh, I used to go there a lot with my daughter a few years ago.

L'imparfait is very helpful for setting a background and creating a mood. In his poem "Barbara," Jacques Prévert sets the scene by describing the incessant rain in the city of Brest, which was destroyed during the Second World War:

Il pleuvait sans cesse sur Brest ce jour-là

It was raining nonstop in Brest that day

Later on, the poet uses the imparfait again to describe the romantic encounter that follows:

Tu souriais

You were smiling

Et moi je souriais de même

And I smiled back

(Note that we used the perfect tense in English for je souriais [I smiled]. The French imparfait does not always correspond to the English imperfect, as we'll discuss further below.)

Prévert then adds more to the background: a man who s’abritait (was taking shelter) under a porch and interrupted the scene with a shout. Whereas the imparfait is used for background or habitual actions, single actions interrupting an ongoing action are usually expressed in passé composé:

Un homme sous un porche s'abritait

A man was taking shelter under a porch

Et il a crié ton nom

And he shouted your name

While all verbs can be conjugated in both the passé composé and the imparfait, certain verbs by their very nature express a state of mind, an attitude, a condition, or a desire, thus lending themselves better to the use of the imparfait. These verbs include avoir (to have), croire (to believe), désirer (to desire), espérer (to hope), être (to be), penser (to think), pouvoir (to be able to), savoir (to know), vouloir (to want). Note that some of these verbs don’t usually take the imperfect in English. For example, we can say on savait, but we don’t really say “we were knowing” in English. In the video below, on ne savait pas translates as "we didn't know":

On ne savait pas que le marché de Noël ouvrait aujourd'hui

We didn't know that the Christmas market was opening today

In another example using the verb penser (to think), the imperfect form is necessary for expressing repetition in French, but not in English:

Je pensais souvent à toi.

I often thought of you.

However, just like in English, when referring to a completed action, we switch to passé composé in French. In the example below, the action was completed hier (yesterday), hence the use of the perfect tense (j’ai pensé). So, paying attention to adverbs in French can help you choose the correct tense:

J’ai pensé à toi hier.

I thought of you yesterday.

In some rare cases, a verb's meaning can change depending on what tense it's in. For example, the verb connaître (to know) usually means “to know” in the imparfait but "to meet" in the passé composé:

Je l'avais fréquenté pendant plusieurs années et je le connaissais.

I had socialized with him for several years, and I knew him.

J'ai connu Gérard y a une dizaine d'années.

I met Gérard about ten years ago.

In the first example, the speaker uses the imparfait to describe an old acquaintance she has known for a long time—something in the past that has an effect on the present. In the second example, we're dealing with a singular event that can't be repeated, when the speaker first met Gérard. So the passé composé is in order here. 

Sometimes certain grammatical structures dictate which tense you should use. For example, to describe hypothetical situations, we use the construction si + imparfait. Zaz uses this construction throughout her song "Si" (If):

Si j'étais l'amie du bon Dieu

If I were the good Lord's friend
