French Imperfect Tense (Imparfait): How to Form It and Use It Naturally

The French imperfect tense, l'imparfait, is the past tense you use for habits, ongoing background actions, and states or descriptions in the past, like je parlais (zhuh par-LAY), meaning “I was speaking” or “I used to speak” depending on context.

French is spoken by hundreds of millions of people worldwide and is used across multiple continents, so mastering core story tenses like imparfait vs passé composé pays off fast in real listening, from everyday conversations to movies (see Ethnologue and the OIF for global figures and reach).

If you want a quick refresher on greeting lines you will actually hear in scenes, pair this with how to say hello in French and how to say goodbye in French, then come back to the grammar that makes the dialogue flow.

What the imperfect means (in plain English)

The imperfect is about unfinished past time.

Not “unfinished” because the action failed, but because the sentence does not frame it as completed. It frames it as in progress, habitual, or simply true at that time.

The two English translations that confuse people

The same French form can map to two common English patterns:

• “was/were + -ing”: je parlais = “I was speaking”
• “used to / would”: je parlais = “I used to speak” or “I would speak”

French does not need a special “used to” tense. Context does the job.

How to form l'imparfait (step by step)

Formation is one of the most learner-friendly parts of French grammar.

You build the imperfect from the nous form of the present tense.

Step 1: take the present “nous” form

Example with parler:

• nous parlons (noo par-LOHN)

Step 2: remove -ons to get the stem

• parl-

Step 3: add imperfect endings

Pronunciation tip: -ais / -ait / -aient are usually pronounced the same in modern standard French, which is why listening alone can feel tricky at first.

The one big exception: être

The imperfect of être uses a special stem:

• nous sommes (noo SOM) → stem ét-

So you get:

• j'étais (zhay-TAY)
• tu étais (tyoo ay-TAY)
• il était (eel ay-TAY)
• nous étions (noo ay-tee-OHN)
• vous étiez (voo ay-tee-AY)
• ils étaient (eel ay-TAY)

This is the form you hear constantly in flashbacks and childhood stories.

Spelling rules you actually need (and why they exist)

French spelling changes in the imperfect are mostly about keeping pronunciation stable.

-cer verbs: c becomes ç before a

With commencer:

• nous commençons → commenç- → je commençais (zhuh koh-mahn-SAY)

The ç keeps the soft “s” sound before “a”.

-ger verbs: add an e to keep the soft g

With manger:

• nous mangeons → mange- → je mangeais (zhuh mahn-ZHAY)

That extra “e” helps keep the “zh” sound.

Stems ending in i: the “nous” and “vous” forms look doubled

With étudier:

• nous étudiions, vous étudiiez

It looks odd, but it is regular: stem étudi- + -ions/-iez.

When to use the imperfect (the 5 core uses)

Reference grammars like Collins French Grammar and usage notes from the Académie française describe the imperfect as a tense of duration, repetition, and description. Here is the practical version you can apply while watching scenes.

1) Past habits and routines

If it happened repeatedly, without focusing on start or end, use imperfect.

• Quand j'étais petit, je jouais dehors.
  (kohn zhay-TAY puh-TEE, zhuh zhoo-AY duh-HOR)
  “When I was little, I used to play outside.”

2) Ongoing background action (the “was doing” frame)

This is the classic setup for an interruption.

• Je regardais la télé quand tu as appelé.
  (zhuh ruh-gar-DAY lah tay-LAY kohn tyoo ah ah-PLAY)
  “I was watching TV when you called.”

Imperfect = background. Passé composé = interrupting event.

3) Descriptions in the past (people, places, atmosphere)

This is why the imperfect is everywhere in storytelling.

• Il faisait froid, et la rue était vide.
  (eel fuh-ZAY frwah, ay lah ryoo ay-TAY VEED)
  “It was cold, and the street was empty.”

4) Mental states, feelings, and opinions (as ongoing states)

Many verbs of state naturally lean imperfect in the past.

• Je pensais que c'était vrai.
  (zhuh pahn-SAY kuh say-TAY vray)
  “I thought it was true.”

5) Polite softening (especially with vouloir, pouvoir)

In real-life French, imperfect can make a request sound less abrupt.

• Je voulais vous demander quelque chose.
  (zhuh voo-LAY voo duh-mahn-DAY kel-kuh SHOZ)
  “I wanted to ask you something.”

This is not “past time” in the story sense. It is a politeness strategy you will hear in shops, offices, and customer service.

Imparfait vs passé composé: the movie-scene rule

If you only remember one thing, remember this:

• Imparfait: the scene, the background, what was ongoing, what used to happen
• Passé composé: the event, what happened once, what moved the story forward

This matches how narratives are structured, a point discussed in many French pedagogy traditions and in classic tense-aspect explanations like those in Bernard Comrie’s work on aspect (useful for understanding why “completed vs ongoing” is not just about time).

A clear contrast pair

• Tous les étés, on allait à Marseille. (too lay ay-TAY, oh-nah-LAY ah mar-SAY)
  “Every summer, we used to go to Marseille.” (habit)

• L'été dernier, on est allé à Marseille. (lay-TAY dehr-NYAY, oh-nay-tah-LAY ah mar-SAY)
  “Last summer, we went to Marseille.” (completed trip)

The “when” trap: quand + imperfect is normal

Learners sometimes think quand forces passé composé. It does not.

• Quand j'habitais ici, je connaissais tout le monde.
  (kohn zhah-bee-TAY ee-SEE, zhuh koh-neh-SAY too luh MOHND)
  “When I lived here, I knew everyone.”

Here, quand introduces a time frame. The imperfect shows that the situation was ongoing during that frame.

Common verbs you will hear in the imperfect (and how they sound)

These show up constantly in dialogue, especially in flashbacks, explanations, and relationship talk.

être

• j'étais (zhay-TAY)
• c'était (say-TAY)

You will hear c'était in everything from nostalgia to complaints.

avoir

• j'avais (zhah-VAY)
  Often used for age, possessions, and conditions: j'avais 20 ans.

aller

• j'allais (zhah-LAY)
  Often means “I was going” or “I was about to”: j'allais partir.

faire

• je faisais (zhuh fuh-ZAY)
  Used for weather and background actions: il faisait nuit.

vouloir

• je voulais (zhuh voo-LAY)
  Polite requests and softened intentions.

If you are building everyday emotional range, this pairs naturally with how to say I love you in French, because relationship scenes often mix imperfect background with passé composé turning points.

The imperfect in negatives and questions

The mechanics are the same as other tenses.

Negation

• Je ne parlais pas. (zhuh nuh par-LAY pah)
  “I wasn’t speaking.”

• Il n'était pas là. (eel nay-TAY pah lah)
  “He wasn’t there.”

Questions

In casual speech, intonation is common:

• Tu parlais à qui ? (tyoo par-LAY ah kee)
  “Who were you talking to?”

Or with est-ce que:

• Est-ce que tu parlais français ? (ess kuh tyoo par-LAY frahn-SAY)
  “Did you speak French / Were you speaking French?”

Mistakes that make you sound non-native (and the fixes)

Mistake 1: using passé composé for long descriptions

Learners often overuse passé composé because it feels like “past tense”.

But French uses imperfect for descriptions:

• Natural: Il faisait beau. (eel fuh-ZAY boh)
• Awkward: Il a fait beau. (eel ah fay boh)
  The second can work, but it implies the weather “happened” as a bounded event, which is not what you usually mean.

Mistake 2: forgetting the “nous stem” rule and guessing

If you guess stems from the infinitive, you will miss irregularities.

Example:

• boire: nous buvons → je buvais (zhuh byoo-VAY), not je boivais

Mistake 3: mixing up pronunciation with spelling (-aient)

In ils parlaient, the ending looks complex but sounds like par-LAY.

This is why reading practice helps: your ear will not always tell you which spelling you need.

How natives use imparfait in real conversation (not just textbooks)

Textbooks often present the imperfect as “used to” and stop there.

In real French, the imperfect is a tool for explaining, justifying, and setting context.

“I was just…” explanations

• Je voulais juste te dire… (zhuh voo-LAY zhyoo-stuh tuh deer)
  “I just wanted to tell you…”

It can soften the intent, especially before delivering news.

Backgrounding to reduce blame

• Je ne savais pas. (zhuh nuh sah-VAY pah)
  “I didn’t know.”

This frames ignorance as a state, not a deliberate act. In conflict scenes, that nuance matters.

Nostalgia and storytelling

French nostalgia often leans on imperfect because it paints a continuous past.

If you watch French films, you will hear strings like: On était jeunes, on sortait tout le temps, on connaissait tout le monde.

If you want to understand how tone shifts when French gets sharp or emotional, compare that to the vocabulary in French swear words, where speakers often switch to short, completed-event phrasing for impact.

Practice: build the imperfect from real “nous” forms

Pick five verbs you actually use, then do this drill:

1. Say the “nous” present form out loud.
2. Remove -ons.
3. Add endings.

Here are good high-frequency choices:

• parler: nous parlons → je parlais
• finir: nous finissons → je finissais
• prendre: nous prenons → je prenais
• venir: nous venons → je venais
• être: nous sommes → j'étais

A quick note on learning it through clips

The imperfect is easier to acquire when you hear it in context-rich scenes: flashbacks, childhood stories, “before we met” conversations, and background descriptions.

That is also why movie-based learning works well for tense-aspect: you see the scene, then the grammar matches what your brain already understands about the timeline. For more on using media effectively, browse the Wordy blog and combine grammar study with short, repeatable listening loops.

Summary: the imperfect in one mental model

Use l'imparfait when you are talking about the past as a state, a habit, or an ongoing background.

Use passé composé when you want a completed event that advances the story.

Once you start hearing French as “scene vs event,” the choice becomes much more automatic.

If you want structured listening practice that makes these contrasts stick, learn French with short dialogue clips on Wordy, then rewatch the same moment until you can predict whether the next verb will be imperfect or passé composé.
