French Imperfect: The Tense You Need to Describe Incredible Past Journeys

Get a hold of your hat, because I’m about to blow your mind and tell you that there is another way besides the perfect tense to talk about the past in French.

The imperfect tense by itself is crucial for talking about way-back-when, but is also a gateway drug to other tenses (the conditional and the pluperfect, just to name a few).

So to make this perfectly simple… er, uhm, imperfectly simple, we’ll go through this nice and easy.


The Building Blocks of the Imperfect Tense

Pay close attention, because this is a tense that will not quit. You’ll hear it in movies, in literature and just about any conversation.

Before we get into the semantics of the imperfect tense, let’s get through the easiest part: forming it. Luckily, for those of you who are already hiding under your desk from PTSD from forming the perfect tense, the imperfect is not a compound tense and has way way way fewer irregular verbs than the perfect. So come out of there, will ya?

French verb stems

First, let’s remember that the stems are just what we derive from the verb before we add the ending. For the verbs that aren’t irregular and rebellious, we simply use the nous form of the verb and drop the –ons at the end. Like so…

Parler (to speak)
Nous form: parlons
Stem: parl-

Finir (to finish)
Nous form: finissons
Stem: finiss-

Prendre (to take)
Nous form: prenons
Stem: pren-

If you know the nous form of any verb, then you know the stem if you chop off the –ons. That’s good news if your present tense conjugations are fresh, and bad news if that’s not your strong suit.

The only irregular stem is that for être (this verb is always getting into trouble). This is because its nous form is sommes, and there’s no doing anything with that. The stem for être is ét-. 

They’re ready, they’re waiting, they’re in the imperfect terminal and ready for those endings!

French imperfect tense endings

The easy part: All you need to do is memorize the endings and we’re there.

Je  -ais
Tu  -ais
Il/Elle  -ait
Nous  -ions
Vous  -iez
Ils/Elles -aient 

Add A to B, and voilà! we’ve got the imperfect tense:

Je parlais (I was speaking)
Tu finissais (You were finishing)
Il prenait (He was taking)
Elle sautait (She was jumping)
Nous choisissions (We were choosing)
Vous disiez (You were saying)
Ils marchaient (They were walking)
Elles conduisaient (They were driving)

Things to keep in mind

When forming the imperfect, you’ve got two parts: your nous stem and your endings. You probably think you have the stem thing on lock right now, since it’s just the nous form—for every verb but êtrebut make sure you are confident with those spellings.

Take étudier (to study) for example, the nous form is étudions. So what? You ask.

Well, that would make the stem étudi- (careful, not étud-). If our stem is étudi-, when we mix in part two (our endings) then we’re stuck with:

Tu étudiais
Il/Elle étudiait
Nous étudiions
Vous étudiiez
Ils/Elles étudiaient 

Did you catch it? There’s an “ii” in there, which is disturbing to look at for some, but yes, you are forming this correctly, even if it is funny looking.

In addition, watch out for verbs that end with -cer or ger. The nous form of these verbs have pesky little spelling changes in the present tense:

Commencer (to start) and other –cer verbs are conjugated like:

Nous commençons, making the imperfect stem commenç-

Nager (to swim) and other –ger verbs are conjugated like:

Nous nageons (with an e) making the stem nage-

Apart from the nous conjugations that you have to keep an eye out for, you fair pretty well with this tense, don’t you? Only one irregular verb compared to the daunting amount of irregular verbs the perfect tense burdens us with.

When to Use the French Imperfect Tense

So when the heck do we use this anyway? Well, to start, it’s not interchangeable with the perfect tense, despite both of them being past tenses. The imperfect tense has many uses, so we’ll just tick them off one by one, nice and easy.

When the amount of time is vague

This is perhaps the most general rule of its usage.

Think of the perfect tense as something that happened at a definite moment, perfect because the action had a beginning and an end.

With the imperfect tense, it is something that happened and happened for an undetermined amount of time. It happened in an imperfect amount of time, aka undefined.

This will come more into play when we start mixing our tenses together.

You are describing how something looked or felt

Let’s say you are weaving a story about your past, lots of details and descriptions because you’re fancy. When you are describing how things looked or how you felt, you use the imperfect tense:

Quand j’étais petite, ma maison était verte. J’avais peur des monstres sous mon lit. 

(When I was young, my house was green. I was scared of the monsters under my bed).

Since you are describing things in the past and your emotions, you would use the imperfect tense (think back to the first usage rule: the house was green for an indeterminable amount of time). Think of the imperfect tense as the setting; you’re creating the background for a story as you speak about the past.

You are wishing upon a star

This will mix in with our conditional tense later on, but if you are expressing a wish using si (if), then you will want to use the imperfect tense:

Si seulement j’avais beaucoup d’argent! (If only I had a lot of money!)

It can also be used in the case of a suggestion, as in “How about we…”

Si nous allions au cinéma? (How about we go to the movies?)

With certain special phrases

If you use the phrase “être en train de (to be in the middle of) and are talking about the past, then you would use the imperfect tense:

J’étais en train de sortir. (I was in the middle of leaving).

Also, using venir de in the past takes the imperfect. This phrase is essentially the equivalent of “just had.”

Nous venions de déjeuner. (We had just had lunch).

Mixing the French Imperfect with Other Tenses

Some tenses mix like peanut butter and jelly or Nutella and French bread (if we’re staying culturally accurate). Some do not. Don’t just go putting your peanut butter (the imperfect tense) with onions!

With the perfect tense

You will use the imperfect tense with the perfect tense the most often. In fact, the imperfect tense acts as a great set-up for the perfect tense in many cases. Think of it this way: Your imperfect tense is moseying along, happening and happening for an undetermined amount of time then BAM, something else happens. That something else is the perfect tense.

Here are a few examples:

Je regardais la télévision quand un singe est apparu dans ma chambre.
(I was watching the TV when a monkey appeared in my room.)

Je mangeais une tarte quand j’ai trouvé une clé dans ma part.
(I was eating a pie when I found a key in my slice.)

Je suis tombée quand je courais.
(I fell when I was running.)

If you aren’t certain that you are using the tenses correctly, then translate it to English and see how it sounds. Both of these tenses translate well into English most of the time. You wouldn’t say: I was eating a pie when I was finding a key in my slice. That doesn’t mean what you are trying to say.

Remember: The perfect tense, because she’s a prissy perfectionist, interrupts the imperfect tense (so rude!).

With the imperfect subjunctive

RED ALERT: If you’re a beginner, you can skip over this section. You won’t be missing out on vital information; I promise. Intermediate and advanced learners may want to stick around just to get the whole gamut of French grammar!

If you aren’t familiar with the subjunctive, stop what you’re doing and get familiar, because it’s important.

Good? Got it? At least the gist? Then here we go…

The imperfect subjunctive is a literary tense, much like the past simple, which means you only need to know how to recognize it. You’d only need to know how to write it if you plan on writing French literature.

The imperfect subjunctive is used to express the subjunctive mood in the past. If your main clause is in the imperfect tense, then you’ll have to use the imperfect subjunctive in the clause following que.

Like so:

Il était content que nous aimassions son gâteau.
(He was happy that we liked his cake).

Until you are ready to dive deep into the depths of literature, that’s about as much as you need to know. Lucky you, because it’s not the easiest fish to fry as far as conjugations go. Though, it’s important to know all of the places you can expect to see the imperfect (even when reading).

With the conditional

Ah, back to those wishes and wants. Good old si sentences. There are three different types, but we’ll concentrate on our new friend, the imperfect, in this post.

In imperfect + conditional si clauses, you are expressing something that would happen if something else happened. It usually expresses things that are unlikely. Fat chance. Yeah right. Don’t get your hopes up.

For example:

Si j’avais un milliard d’euros, j’achèterais deux maisons.
(If I had a million euros, I would buy two houses.)

Nous serions amis si tu étais plus gentil.
(We would be friends if you were nicer.)

If you are doing a double take in the face of the conditional, then check out how to form it and how you would use it if you knew how, here.

Tip: The imperfect and the conditional use the same endings. So if you are feeling particularly ambitious right now, the conditional is a great tense to learn in conjunction with the imperfect!


Your imperfect usage may not be perfect at first (Get it? Get it?), but it’s a tense that will lurk around and beg to be used for the entire duration of your French learning experience. Now you know where you’ll see it, when you’ll use it, and the easiest part, how to form it.

It’s recommended that you practice the imperfect tense by seeing how it’s used in context. That way, you can really get a hang of how this tense is realistically used in different situations. For this, you can check out authentic French content, the kind of stuff made for and by native speakers.

Authentic French content can be French books, podcasts on Spotify or videos on YouTube—for anything you consume, see if you can spot instances of the tense. For a more learner-tailored approach, there’s the language learning program FluentU and its video library. Each clip comes with interactive captions that provide definitions, grammatical information and usage examples for any spoken word. This lets you understand proper behavior and conjugation of verbs in different tenses.

Since you’ve mastered the past, I guess it’s time for you to travel into the future; you may like what you see. Become the master of the French space-time continuum (okay, so it’s not quite that exciting)!
