When you form the perfect tense with être, the past participle agrees with the subject of the verb (the person doing the action):

• add -e to the past participle for feminine singular --> allée
• add -s for masculine plural --> allés
• add -es for feminine plural --> allées

So the perfect tense of aller (to go) is:

• je suis allé(e)
• tu es allé(e)
• il/elle/on est allé(e)
• on est allé(e)(s)
• nous sommes allé(e)s
• vous êtes allé(e)(s)
• ils/elles sont allé(e)s

• Monter = monté (went up)
• Retourner = retourné (returned)
• Sortir = sorti (went out)
• Venir = venu (came)
• Arriver = arrivé (arrived)
• Naître = né (was born)
• Descendre = descendu (went down)
• Entrer = entré (entered)
• Rester = resté (stayed)
• Tomber = tombé (fell)
• Rentrer = rentré (went back in)
• Aller = allé (went)
• Mourir =mort (died)
• Partir =parti (left)

To form the imperfect tense of all verbs take the nous form of the present tense, eg avoir --> nous avons and drop the nous and the -ons and add the imperfect endings, eg:

• j'avais
• tu avais
• il/elle/on avait
• nous avions
• vous aviez
• ils/elles avaient

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

Conjugating regular -er, -ir and -re verbs to form the present tense

                      -er verbs parler                      -ir verbs choisir                      -re verbs vendre

je                         parle                                     choisis                                         vends

tu                        parles                                     choisis                                        vends

ils/elles               perlent                                    choisissent                                 vendent

The immediate future tense is used to talk about what is going to happen in the future.

It's formed by combining both:

• the present tense of the verb aller
• the infinitive of the main verb

Je vais

Tu vas

Il/elle/on va

Nous allons

Vous allez

Ils/elles vont

Forming the conditional tense
