Learning to talk about the past in French can be confusing, especially when you have to choose between l’imparfait and le passé composé.
Both tenses are used to talk about past events, but they have different roles. The easiest way to understand the difference is to think about what you want to say about the past.
Are you describing a situation, a habit, or something that was happening? Use the imparfait.
Are you talking about a specific, completed event? The passé composé is usually the right choice.
Let’s look at the difference step by step.
1. When to Use the Imparfait
The imparfait is used to describe situations and actions that were happening in the past.
It is commonly used for:
- Descriptions
- Past habits
- Repeated actions
- Background information
- Actions that were in progress
Think of the imparfait as the background of a story.
Describing a Past Situation
Use the imparfait when you want to describe what something or someone was like.
Examples:
Il faisait froid.
It was cold.
La maison était grande.
The house was big.
J’étais fatigué.
I was tired.
Le ciel était bleu.
The sky was blue.
These sentences describe a situation rather than a specific event.
2. The Imparfait for Past Habits
The imparfait is also used when talking about things you used to do or things that happened regularly in the past.
Common expressions include:
- souvent — often
- toujours — always
- d’habitude — usually
- chaque jour — every day
- tous les dimanches — every Sunday
- quand j’étais enfant — when I was a child
Examples
Quand j’étais enfant, je jouais au football tous les jours.
Nous allions souvent au parc.
Elle regardait toujours des dessins animés le dimanche.
Chaque été, nous visitions nos grands-parents.
The important idea is that these actions were habitual or repeated, rather than one-time events.
3. When to Use the Passé Composé
The passé composé is generally used for a specific action or event that is completed in the past.
It is often used to answer the question:
“What happened?”
Examples
J’ai mangé une pizza.
Elle a appelé son ami.
Nous avons regardé un film.
Ils sont arrivés à huit heures.
Each action is presented as a completed event.
4. Imparfait vs Passé Composé: The Basic Difference
Compare these two sentences:
Je regardais la télévision.
J’ai regardé la télévision.
The first sentence uses the imparfait. It focuses on the activity as something that was happening.
The second uses the passé composé. It presents watching television as a completed event.
A useful way to remember this is:
Imparfait → What was happening?
Passé composé → What happened?
This is not a perfect rule for every situation, but it is an excellent starting point for beginners.
5. Imparfait = Background, Passé Composé = Main Event
One of the easiest ways to understand these tenses is to imagine that you are telling a story.
The imparfait gives us the background.
The passé composé tells us what happened.
For example:
Il faisait nuit. Je marchais dans la rue quand j’ai entendu un bruit.
There are three important elements here:
Il faisait nuit → description → imparfait
Je marchais dans la rue → action in progress → imparfait
J’ai entendu un bruit → specific event → passé composé
The imparfait creates the scene, while the passé composé introduces the event.
6. When One Action Interrupts Another
This is one of the most common situations where French learners use both tenses together.
When an action was already happening and another event interrupted it, the ongoing action is usually expressed with the imparfait, while the interrupting event is expressed with the passé composé.
Examples
Je dormais quand le téléphone a sonné.
Nous mangions quand Marie est arrivée.
Il travaillait quand son patron l’a appelé.
Je regardais un film quand mon ami m’a envoyé un message.
In each example:
Imparfait = action already in progress
Passé composé = new event that happened
This pattern is extremely useful when telling stories in French.
7. Using the Passé Composé for a Sequence of Events
When several completed actions happen one after another, French often uses the passé composé.
For example:
Je me suis levé, j’ai pris une douche et j’ai préparé mon petit-déjeuner.
The actions happen in sequence:
- Je me suis levé.
- J’ai pris une douche.
- J’ai préparé mon petit-déjeuner.
These are individual completed events, so the passé composé works naturally.
Another example:
Elle est rentrée, elle a préparé le dîner et elle a regardé un film.
The events move the story forward.
8. Using Both Tenses in a Story
In real French, the imparfait and passé composé are often used together.
Consider this example:
Il faisait beau et les oiseaux chantaient. Je marchais dans le parc quand j’ai rencontré Paul. Nous avons parlé pendant quelques minutes, puis nous sommes allés prendre un café.
Let’s break it down.
Il faisait beau → description → imparfait
Les oiseaux chantaient → background action → imparfait
Je marchais dans le parc → action in progress → imparfait
J’ai rencontré Paul → completed event → passé composé
Nous avons parlé → completed event → passé composé
Nous sommes allés prendre un café → completed event → passé composé
This is a very common structure in French storytelling.
9. How to Form the Imparfait
The imparfait is relatively regular.
For most verbs, take the nous form of the present tense, remove -ons, and add the imparfait endings.
| Subject | Ending |
|---|---|
| Je | -ais |
| Tu | -ais |
| Il / Elle | -ait |
| Nous | -ions |
| Vous | -iez |
| Ils / Elles | -aient |
For example, with parler:
Present:
Nous parlons.
Remove -ons:
parl-
Then add the endings:
Je parlais.
Tu parlais.
Il parlait.
Nous parlions.
Vous parliez.
Ils parlaient.
The important exception to remember is être:
J’étais.
Tu étais.
Il était.
Nous étions.
Vous étiez.
Ils étaient.
10. How to Form the Passé Composé
The passé composé is generally formed with:
auxiliary verb + past participle
The auxiliary is usually avoir or être.
With Avoir
J’ai mangé.
Nous avons regardé un film.
Elle a terminé son travail.
With Être
Some verbs use être as their auxiliary.
Je suis arrivé.
Elle est partie.
Nous sommes venus.
Ils sont rentrés.
With être, the past participle generally agrees with the subject.
For example:
Elle est arrivée.
Ils sont partis.
11. Useful Clues
Certain expressions can help you identify which tense might be appropriate.
Expressions often used with the imparfait
- souvent — often
- toujours — always
- d’habitude — usually
- chaque jour — every day
- tous les ans — every year
- quand j’étais enfant — when I was a child
Example:
Quand j’étais enfant, je jouais souvent au football.
Expressions often used with the passé composé
- hier — yesterday
- soudain — suddenly
- tout à coup — all of a sudden
- une fois — once
- ce matin — this morning
- à huit heures — at eight o’clock
Example:
Hier, j’ai rencontré un ancien ami.
However, these expressions are clues, not absolute rules. The context and meaning of the sentence are more important.
12. A Simple Question to Ask Yourself
When you are unsure which tense to use, ask yourself:
Am I describing what things were like or what was happening?
If yes, think about the imparfait.
Il pleuvait.
Je lisais un livre.
Am I describing a specific event that happened and was completed?
If yes, think about the passé composé.
Il a commencé à pleuvoir.
J’ai terminé le livre.
This simple distinction can help you make the right choice much more often.
13. A Final Story to See the Difference
Here is a short story using both tenses:
C’était samedi matin. Il faisait beau et les enfants jouaient dans le jardin. Leur mère préparait le déjeuner quand quelqu’un a frappé à la porte. Elle a ouvert la porte et elle a découvert son frère. Il était de passage dans la ville.
Notice how the tenses work together.
C’était samedi matin → background → imparfait
Il faisait beau → description → imparfait
Les enfants jouaient → action in progress → imparfait
Leur mère préparait le déjeuner → action in progress → imparfait
Quelqu’un a frappé à la porte → specific event → passé composé
Elle a ouvert la porte → completed event → passé composé
Elle a découvert son frère → completed event → passé composé
Il était de passage → description/situation → imparfait
The two tenses work together to make the story clear and natural. Once you start thinking about whether you are setting the scene or telling what happened, choosing between the imparfait and passé composé becomes much easier.
