Avoir vs Être
Choosing the right auxiliary verb for compound tenses in French
The Basic Rule
In French compound tenses (like passé composé), you need an auxiliary verb + past participle. Most verbs use avoir, but some special verbs use être.
AVOIR (Most Verbs)
Use "avoir" with:
- • Most verbs (90%+ of them)
- • All transitive verbs (verbs with direct objects)
- • Action verbs (manger, boire, faire, etc.)
Example:
J'ai mangé une pomme.
(I ate an apple)
ÊTRE (Special Verbs)
Use "être" with:
- • DR & MRS VANDERTRAMP verbs
- • All reflexive verbs (se laver, se lever, etc.)
- • Verbs of motion and state change
Example:
Je suis allé(e) au parc.
(I went to the park)
The DR & MRS VANDERTRAMP Rule
These 16 verbs ALWAYS use "être" as their auxiliary. Memorize this acronym:
DR & MRS
VANDERTRAMP
Devenir
to become
Revenir
to come back
Monter
to go up
Rester
to stay
Sortir
to go out
Venir
to come
Aller
to go
Naître
to be born
Descendre
to go down
Entrer
to enter
Rentrer
to return home
Tomber
to fall
Retourner
to return
Arriver
to arrive
Mourir

Partir

⚠️ Important Note:
When using "être" as auxiliary, the past participle must agree in gender and number with the subject:
- • Il est allé (masculine singular)
- • Elle est allée (feminine singular - add "e")
- • Ils sont allés (masculine plural - add "s")
- • Elles sont allées (feminine plural - add "es")
Reflexive Verbs ALWAYS Use Être
All reflexive verbs (verbs with "se") use être in compound tenses:
Je me suis levé(e)
I got up
Tu t'es lavé(e)
You washed yourself
Elle s'est habillée
She got dressed
Nous nous sommes amusés
We had fun

Memory Tricks & Mnemonics
🏠 The "House of Être"
Imagine a house. DR & MRS VANDERTRAMP verbs are all about movement (arriving, leaving, going up/down, entering) or state changes (becoming, being born, dying, staying). They're the "comings and goings" of the house!
🪞 Reflexive = Mirror Action
If you're doing something to yourself (se laver = wash yourself), think of it as a mirror reflecting back - and mirrors are a form of being, so use "être"!
📊 Default to Avoir
When in doubt, use "avoir" - it's correct 90% of the time! Only switch to "être" if the verb is: (1) in DR & MRS VANDERTRAMP, or (2) reflexive.
