The passé composé is a past tense in French that indicates completed actions. It’s formed using an auxiliary verb (either “avoir” or “être”) and the past participle of the main verb. On the other hand, the Imparfait is another past tense used to describe ongoing or repeated actions in the past. It’s formed by adding specific endings to the stem of the verb.

When to use imparfait

The imparfait tense in French is a past tense used to describe ongoing or habitual actions in the past. It’s often used to set the scene, provide background information, and express states of mind or feelings at a specific time in the past.

1. Describing ongoing actions:

This usage of the l’imparfait emphasizes actions that were ongoing or in progress when another event occurred.

Example: Je mangeais quand il est arrivé. (I was eating when he arrived.) Here, “mangeais” (was eating) indicates an action that was in progress when “il est arrivé” (he arrived), which is expressed in the passé composé tense.

2. Describing habitual actions:

L’imparfait is also used to describe actions that were habitual or repeated in the past, often in a context where no specific endpoint is mentioned.

Example: Quand j’étais jeune, je jouais au foot tous les jours. (When I was young, I used to play soccer every day.) In this sentence, “je jouais” (I used to play) indicates a habitual action that occurred repeatedly in the past without specifying individual instances.

3. Setting the scene and providing background information

L’imparfait is commonly used in storytelling to provide context and background details about the past.

Example: Il faisait beau. Les oiseaux chantaient. Tout était parfait. (The weather was beautiful. The birds were singing. Everything was perfect.) Here, “faisait” (was) and “chantaient” (were singing) create a vivid scene in the past, setting the mood and atmosphere.

4. Expressing feelings or states of mind: 

L’imparfait can also be used to describe feelings, emotions, or mental states that were ongoing in the past.

Example: Elle était heureuse quand elle habitait en France.(She was happy when she lived in France.) In this sentence, “était” (was) describes a state of happiness that persisted during her time living in France.

When to use passé composé (perfect tense)

1. Describing completed actions:

The passé composé is used to talk about actions that have been completed or happened at a specific time in the past.

Example: Hier, j’ai mangé au restaurant. (Yesterday, I ate at the restaurant.) Here, “ai mangé” (ate) indicates a completed action that occurred yesterday.

2. Narrating a sequence of events:

This tense is also used to narrate a series of completed actions or events that happened one after another.

Example: Je suis rentré chez moi, j’ai préparé le dîner, puis j’ai regardé la télé. (I came back home, prepared dinner, and then watched TV.) In this sentence, “suis rentré” (came back), “ai préparé” (prepared), and “ai regardé” (watched) are all actions completed in the past.

3. Emphasizing the result or outcome:

The passé composé is often used to highlight the result or consequence of an action that took place in the past.

Frequently Asked Questions

How do you use imparfait and passé composé in the same sentence?

To use l’imparfait and Le passé composé in the same sentence, L’imparfait sets the background or ongoing action, while passé composé interrupts with a completed action. For example: “Je lisais un livre quand le téléphone a sonné.” (I was reading a book when the phone rang.) The imparfait (“je lisais”) describes the on going action, and the passé composé (“a sonné”) describes the interruption.

You can identify the l’imparfait by looking for clues indicating ongoing or habitual actions in the past. Common indicators include expressions like “toujours” (always), “souvent” (often), “tous les jours” (every day), and “pendant que” (while). The l’imparfait is used to set the scene, describe background information, and express continuous states or repeated actions.

Is age passé composé or imparfait?
