Historical Context & Motivation
Every language needs a way to distinguish between completed events and the ongoing backdrop surrounding them. In English, you might say "I was walking when it started to rain"—the walking is the background, and the rain is the sudden event. French solves this same storytelling problem with a dedicated verb tense called the imparfait (imperfect). Understanding where this tense came from helps you see why it works the way it does today.
The core question the imparfait answers is this: What was the situation like at a given moment in the past? Rather than reporting what happened next (that's the job of the passé composé), the imparfait describes the scene—the weather outside, the emotions inside a character, and the general atmosphere. Think of it as the "camera pan" before the action begins.
Core Principles & Definitions
Before diving into conjugation charts, you need to understand the three foundational roles the imparfait plays when it sets a background in the past. Each role answers a different kind of "What was going on?" question, and all three can appear in a single paragraph of French storytelling.
Setting & Scenery
Weather & Time
Feelings & States of Mind
Ongoing / In-Progress Actions
Visual Explanation — Imparfait vs. Passé Composé on a Timeline
One of the best ways to understand the imparfait is to see it on a timeline. The following diagram shows how background descriptions (imparfait) stretch across time like a continuous band, while specific events (passé composé) appear as distinct points that interrupt or sit on top of the background.
In the diagram above, imagine you're telling a friend about your day. You start by setting the scene: Il faisait beau, les gens marchaient, j'étais content… All of these use the imparfait because they describe the ongoing conditions. Then something specific happens—j'ai vu un accident—and you switch to the passé composé. The background keeps running; the event lands on top of it.
How It Works — Forming the Imparfait
The great news about the imparfait is that its formation is almost entirely regular. There is only one irregular verb in the imparfait: être. Every other verb—including notoriously tricky ones like avoir, faire, aller—follows the same two-step process.
| Subject Pronoun | Ending | parler (stem: parl-) | finir (stem: finiss-) |
|---|---|---|---|
| je | -ais | je parlais | je finissais |
| tu | -ais | tu parlais | tu finissais |
| il / elle / on | -ait | il parlait | elle finissait |
| nous | -ions | nous parlions | nous finissions |
| vous | -iez | vous parliez | vous finissiez |
| ils / elles | -aient | ils parlaient | elles finissaient |
Three Categories of Background Description
Now that you know how to form the imparfait, let's focus on when to use it for background details. French textbooks and native speakers generally group background imparfait usage into three overlapping categories: physical setting, weather and time, and internal states. The diagram below organizes these categories with example sentences so you can see the pattern at a glance.
A useful trick is to ask yourself: "Could I translate this with 'was' or 'were' plus an -ing form, or simply with 'was' plus an adjective?" If the answer is yes, you're almost certainly looking at an imparfait situation. It was raining → Il pleuvait. She was happy → Elle était contente. This test won't cover every case, but it handles most background descriptions reliably.
Worked Example — Writing a Paragraph with Background Details
Let's walk through the process of writing a short French paragraph that combines background descriptions (imparfait) with a main event (passé composé). We'll start with an English scenario and translate it step by step.
Imparfait vs. Passé Composé — Side-by-Side Comparison
The number-one challenge for French 2 students is choosing between the imparfait and the passé composé. They aren't interchangeable—each tense tells the listener something different about the action. The table below highlights the key differences so you can make confident choices in your writing and speaking.
| Feature | Imparfait | Passé Composé |
|---|---|---|
| What it expresses | Background, ongoing states, descriptions, habitual actions | Completed, specific events with a clear beginning and/or end |
| English equivalent | "was doing," "used to do," "was [adjective]" | "did," "has done" |
| Timeline image | A continuous, open-ended band (no defined start/end) | A single dot or short bounded segment |
| Key signal words | d'habitude, tous les jours, souvent, pendant que, quand (background) | soudain, tout à coup, un jour, hier, à 3 heures |
| Weather | Il pleuvait. (It was raining — backdrop) | Rarely used for weather (only if emphasizing a sudden change) |
| Feelings | Elle était contente. (She was happy — state) | Elle a été surprise. (She was surprised — sudden reaction) |
Connection to Advanced French Tenses
The imparfait is your first deep dive into the idea that French uses different tenses to express different aspects of the past—not just different times. This concept of grammatical aspect becomes even more important as you advance. The table below previews how the imparfait connects to tenses you'll encounter in French 3, French 4, and AP French.
| Tense / Structure | Connection to Imparfait | When You'll Learn It |
|---|---|---|
| Plus-que-parfait | Uses imparfait of avoir/être + past participle to express "had done" — background before the background. | French 3 |
| Conditionnel présent | Shares the same stem as the imparfait (nous-form minus -ons) but uses future endings. Used for hypotheticals. | French 3 / 4 |
| Si clauses (hypotheticals) | "Si j'avais de l'argent..." — the imparfait appears in "si" clauses to express unreal present conditions. | French 4 / AP |
| Literary past tenses | In literature, the imparfait pairs with the passé simple (instead of the passé composé) for the same background vs. event contrast. | AP French |
Mastering the imparfait now gives you a huge head start. The formation pattern you learned (nous stem + endings) will reappear almost identically when you study the conditionnel. And the idea of choosing tenses based on aspect rather than just time will guide every advanced grammar decision you make in French.

Lesson Summary
The imparfait is the French past tense dedicated to background description. It covers three main areas: physical settings (what a place looked like), weather and time (atmospheric conditions and time of day), and feelings and states of mind (emotions, desires, and thoughts). To form it, take the nous form of the present tense, drop -ons, and add the endings -ais, -ais, -ait, -ions, -iez, -aient. The only exception is être, which uses the stem ét-.
The imparfait works hand-in-hand with the passé composé. Think of the imparfait as the background music that establishes mood, and the passé composé as the sound effects that mark specific events. A quick test: if you can translate the English with "was/were + -ing" or "was + adjective," it's almost always imparfait. Mastering this distinction will transform your French storytelling and prepare you for the plus-que-parfait, the conditionnel, and si clauses in your future French studies.
