Understanding the Imparfait Tense

The Imparfait tense, also known as the Imperfect tense, is used to describe actions or situations that occurred in the past and were ongoing or repeated.

Formation of the Imparfait Tense

To form the Imparfait tense, follow these steps:

1. Take the verb in its present tense ‘nous’ form (e.g., ‘nous parlons’ for ‘parler’).
2. Remove the ‘-ons’ ending to find the stem (e.g., ‘parl-‘ for ‘parler’).
3. Add the following endings to the stem:

• je: -ais
• tu: -ais
• il/elle/on: -ait
• nous: -ions
• vous: -iez
• ils/elles: -aient

Example:

• parler (to speak)
  • je parlais
  • tu parlais
  • il/elle/on parlait
  • nous parlions
  • vous parliez
  • ils/elles parlaient

Uses of the Imparfait Tense

The Imparfait tense is used in several situations:

1. Habitual actions – Actions that happened regularly in the past.
   • Example: Nous allions à l’école à pied. (We used to go to school on foot.)
2. Ongoing actions – Actions that were in progress when another event occurred.
   • Example: Il pleuvait quand nous sommes sortis. (It was raining when we went out.)
3. Descriptive background – Setting the scene or providing background information.
   • Example: Il faisait froid et il y avait beaucoup de neige. (It was cold and there was a lot of snow.)
4. Emotions and desires – Expressing feelings, thoughts, or desires in the past.
   • Example: J’aimais beaucoup le chocolat. (I really liked chocolate.)

Understanding the Passé Composé Tense

The Passé Composé tense is used to describe completed actions or events that happened in the past.

Formation of the Passé Composé Tense

To form the Passé Composé tense, follow these steps:

1. Choose the appropriate auxiliary verb, either ‘avoir’ or ‘être’.
2. Conjugate the auxiliary verb in the present tense.
3. Add the past participle of the main verb.

Auxiliary Verbs

Most verbs use ‘avoir’ as their auxiliary verb, while some verbs use ‘être’. Verbs that use ‘être’ typically indicate motion or a change of state and include reflexive verbs. To remember which verbs use ‘être’, you can use the acronym ‘DR & MRS VANDERTRAMP’:

• Devenir
• Revenir
• Monter
• Rentrer
• Sortir
• Venir
• Aller
• Naître
• Descendre
• Entrer
• Retourner
• Tomber
• Rester
• Arriver
• Mourir
• Partir

Past Participles

The past participle for regular verbs is formed as follows:

• -er verbs: Replace the ‘-er’ ending with ‘-é’ (e.g., parler → parlé).
• -ir verbs: Replace the ‘-ir’ ending with ‘-i’ (e.g., finir → fini).
• -re verbs: Replace the ‘-re’ ending with ‘-u’ (e.g., vendre → vendu).

For irregular verbs, the past participles need to be memorized. Some common irregular past participles include:

• avoir: eu
• être: été
• faire: fait
• prendre: pris
• voir: vu
• écrire: écrit

Uses of the Passé Composé Tense

The Passé Composé tense is used to describe:

1. Completed actions – Actions that were completed in the past.
   • Example: J’ai mangé une pomme. (I ate an apple.)
2. Single events – Actions that happened once, rather than repeatedly or over a period of time.
   • Example: Il a plu hier. (It rained yesterday.)
3. Actions that interrupt an ongoing action – When referring to an action that interrupted another action in progress.
   • Example: Elle lisait quand le téléphone a sonné. (She was reading when the phone rang.)

Differentiating Between Imparfait and Passé Composé

The main difference between the Imparfait and Passé Composé tenses lies in how the past actions are viewed:

• Imparfait: Describes ongoing, habitual, or repeated actions in the past.
• Passé Composé: Indicates completed actions, single events, or actions that interrupt ongoing actions.

When choosing between these two tenses, consider whether the action in question was ongoing or completed, and whether it was habitual or a single occurrence.

Common Mistakes and How to Avoid Them

1. Misusing the auxiliary verb: Ensure you use the correct auxiliary verb (‘avoir’ or ‘être’) for the main verb in the Passé Composé tense.
2. Incorrect past participle formation: Memorize irregular past participles and apply the correct endings for regular verbs.
3. Choosing the wrong tense: Determine whether the action was ongoing or completed, and whether it was habitual or a single occurrence, before deciding between the Imparfait and Passé Composé tenses.
