Verbes auxiliaires

Auxiliary verbs are also known as helping verbs, because they help form compound conjugations, meaning compound tenses like the passé composé as well as compound moods like the past subjunctive.

The key thing to remember about compound conjugations is that there are two verbs: the auxiliary verb, which conjugates for the required tense or mood, and the main verb, which is always in the form of the past participle.

Par exemple…

J’ai mangé.	I have eaten, I ate.	passé composé
J’avais mangé.	I had eaten.	pluperfect
J’aurai mangé.	I will have eaten.	future perfect

French has only two auxiliary verbs. Avoir is the auxiliary for the vast majority of French verbs, but there are a number of notable exceptions for which être is the auxiliary. Whichever verb it is, the auxiliary is consistent for all compound conjugations: avoir verbs always take avoir as their auxiliary verb for all compound tenses and moods, while être verbs always take être. However, there are a few verbs that can take either auxiliary, depending on how they’re used: learn more.

Être verbs

Since most French verbs take avoir, it makes sense to memorize the relatively short list of the ones that don’t. Verbs that require être as the auxiliary can be divided into two groups:

1. All pronominal verbs

2. Intransitive verbs of movement – when the following verbs are used intransitively*, they require être as their auxiliary:

		And their derivatives…
aller	to go
arriver	to arrive
décéder	to die
descendre	to descend / go downstairs	redescendre – to descend again
entrer	to enter	rentrer – to re-enter
monter	to climb	remonter – to climb again
mourir	to die
naître	to be born	renaître – to be reborn, born again
partir	to leave	repartir – to leave again
passer	to pass	repasser – to come/go back
rester	to stay
retourner	to return
sortir	to go out	ressortir – to go out again
tomber	to fall	retomber – to fall again
venir	to come	devenir – to become parvenir – to reach, achieve revenir – to come again, come back

* Intransitively = without a direct object. Most of these verbs can only be intransitive, so they always require être as the auxiliary. But eight of them can be used transitively, and when that happens, they need avoir.

Être verbs require agreement in all compound tenses.

With practice, you’ll get used to these verbs and know instinctively that they require être, but for right now, you might find one of these mnemonic devices helpful.

La Maison d’être

Native French-speaking teachers teach être verbs by having students draw a house with a door, windows, at least two rooms, and a staircase, and then label it with the être verbs. For example, draw a figure passing in front of the house (passer), another entering it (entrer), and a third going upstairs (monter).

The Infamous Vandertramps

DR & MRS VANDERTRAMP seems to be the standard mnemonic device for être verbs in the United States. I don’t like it – I think including the derivatives is silly, but whatever works for any given student is all that matters.

Also note that passer is missing.

Devenir
Revenir
&
Monter
Rester
Sortir
Venir
Aller
Naître
Descendre
Entrer

ADVENT

Each letter in ADVENT stands for one of the verbs and its opposite, and then there’s one extra verb.

Once again, passer is missing.

Arriver – Partir
Descendre – Monter
Venir – Aller
Entrer – Sortir
Naître – Mourir
Tomber – Rester
Retourner

DRAPERS VAN MMT13
