Auxiliary Verbs – Avoir vs Être

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:

1. Auxiliary verb, whose conjugation determines the tense or mood
2. 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 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

• s’asseoir
• se coucher
• s’enfuir
• s’habiller
• se méfier
• se souvenir
  etc.

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.

Once again, passer is missing.

Arriver – Partir
