Passé Composé vs Imparfait: The Complete Guide to French Past Tenses

The Root of the Confusion

Both passé composé and imparfait describe the past — but they describe it in fundamentally different ways. English learners struggle because English uses the simple past ("I went") for both. In French, the distinction is always made explicit:

• Je suis allé(e) au marché hier. — Passé composé: a completed action
• J'allais au marché tous les samedis. — Imparfait: a recurring habit

Both translate as "I went to the market" in English — but in French they mean very different things.

Passé Composé: Completed, Specific Actions

Use passé composé for:

• A specific, completed action: Il a mangé une pomme. (He ate an apple.)
• An action that happened a set number of times: Nous avons visité Paris trois fois. (We visited Paris three times.)
• A sequence of events: Elle s'est levée, a pris son café et est partie. (She got up, had her coffee, and left.)
• An action with a clear beginning or end: La réunion a duré deux heures. (The meeting lasted two hours.)

Passé Composé Signal Words

These time expressions usually signal passé composé:

• hier (yesterday), avant-hier (day before yesterday)
• la semaine dernière (last week), l'année dernière (last year)
• une fois, deux fois (once, twice)
• soudain, tout à coup (suddenly) — a sudden event interrupts a background
• d'abord... puis... ensuite... enfin (first... then... next... finally) — sequence

Imparfait: Background, Habits, and States

Use imparfait for:

• Habitual or repeated actions in the past: Quand j'étais enfant, je jouais au foot chaque soir. (When I was a child, I played football every evening.)
• Ongoing states or conditions: Il faisait beau et les oiseaux chantaient. (The weather was nice and the birds were singing.)
• Background setting when another action occurred: Je lisais quand le téléphone a sonné. (I was reading when the phone rang.)
• Descriptions of people, places, feelings: La maison était grande. Il avait les yeux bleus.
• Ongoing mental/physical states: Elle voulait partir. Il avait faim.

Imparfait Signal Words

• toujours, souvent, habituellement (always, often, usually)
• tous les jours, tous les soirs (every day, every evening)
• quand j'étais jeune / enfant / petit(e) (when I was young / a child)
• autrefois, jadis (in the old days, formerly)
• pendant que, tandis que (while) — ongoing background

The Classic Pattern: Background + Event

The most tested grammar point at B1/B2 is stories where imparfait provides background context and passé composé delivers the key event:

• Il pleuvait [background: imparfait] quand je suis sorti [event: passé composé].
  It was raining when I went out.
• Nous dînions tranquillement quand quelqu'un a frappé à la porte.
  We were having a quiet dinner when someone knocked at the door.
• Elle était fatiguée, alors elle s'est couchée tôt.
  She was tired, so she went to bed early.

Verbs That Usually Stay in the Imparfait

Certain verbs describe states rather than actions. In narratives, they almost always appear in the imparfait:

• être (to be), avoir (to have)
• savoir (to know — knowledge), croire (to believe)
• penser (to think), vouloir (to want)
• aimer (to love/like), préférer (to prefer)
• pouvoir (to be able to), devoir (to have to — in the sense of "was supposed to")

Exception: These verbs can appear in passé composé when describing a sudden change of state: Soudain, j'ai su la vérité. (Suddenly, I knew the truth.)

The Mental Model That Makes It Click

Think of a movie scene. The imparfait is the camera pan — the slow establishing shot of the setting, the weather, what people were wearing, what they habitually did. The passé composé is the action cut — the event that happens, the plot point that advances the story.

Every past-tense story in French uses both. Master this distinction and you'll handle 90% of past-tense usage correctly — in TCF writing, DELF essays, and everyday conversation.

Quick Practice: Which Tense?

Test yourself — which tense is correct?

1. Quand j'étais petit, je _____ (habiter) à Lyon. → habitais (imparfait — habitual)
2. Hier soir, nous _____ (aller) au cinéma. → sommes allés (passé composé — specific completed action)
3. Il _____ (lire) son livre quand elle _____ (entrer). → lisait / est entrée (background + event)
4. Elle _____ (être) très heureuse ce jour-là. → était (imparfait — emotional state)
5. Nous _____ (visiter) la tour Eiffel trois fois pendant notre séjour. → avons visité (passé composé — specific number of times)
