Using Être & Avoir (Present & Past) — I can use être and avoir accurately in present and past contexts in familiar sentence frames.

If you could only learn two verbs in French, they would be être (to be) and avoir (to have). These verbs are the backbone of the entire language. They help you describe who you are, what you possess, and — crucially — they serve as auxiliary (helping) verbs that unlock every past-tense construction in French. Understanding their evolution helps explain why their conjugation patterns are irregular and why they behave so differently from regular verbs.

So why do these two verbs matter so much for you right now in French 2? The answer is simple: without être and avoir, you cannot talk about the past. The passé composé — the most common past tense in spoken French — always requires one of these two verbs as a helper. This lesson will give you the tools to conjugate both verbs confidently in the present tense and use them to build past-tense sentences in familiar sentence frames.

Before diving into conjugation charts, you need to understand four foundational ideas that govern how être and avoir work in both the present and the past. These principles will keep you from memorizing blindly and help you actually predict the correct forms.

The diagram below places the full present-tense conjugations of être and avoir side by side so you can compare their forms visually. Notice how neither verb follows a predictable pattern — every form is unique. Study the color-coded subject pronouns on the left; they connect to each conjugated form on the right.

A few things to notice in the chart above. First, the singular forms of être — suis, es, est — look completely different from the plural forms — sommes, êtes, sont. This is because the singular forms descend from one Latin root while the plural forms come from another. Second, look at avoir's third-person singular: a — just a single letter! It's the shortest conjugated form in all of French. These quirks make memorization essential; there is no shortcut formula.

The passé composé is called a "compound" tense because it is built from two parts: a conjugated auxiliary verb (être or avoir in the present tense) plus a past participle (participe passé). Think of it as a two-piece construction — the auxiliary carries the person and number information, while the participle carries the meaning of the action.

Forming Past Participles

Which Auxiliary: Avoir or Être?

Most verbs use avoir as their auxiliary. Only a select group of verbs — often memorized with the mnemonic DR MRS VANDERTRAMP — use être. These are mostly verbs of motion or change of state: Devenir, Revenir, Monter, Rester, Sortir, Venir, Aller, Naître, Descendre, Entrer, Rentrer, Tomber, Retourner, Arriver, Mourir, Partir. All reflexive verbs (se laver, se lever, etc.) also use être.

One of the trickiest parts of the passé composé is remembering which verbs use être instead of avoir. The diagram below organizes the DR MRS VANDERTRAMP verbs visually, grouping them by the type of motion or change they describe. Many of these verbs come in natural pairs of opposites — arriver/partir, monter/descendre, naître/mourir — which makes them easier to remember together.

Grouping these verbs by meaning rather than just by the first letter of the mnemonic can help you internalize them faster. If a verb describes someone arriving, leaving, going up, going down, being born, dying, staying, or becoming something, it most likely uses être. All other verbs — eating, speaking, studying, watching, playing — use avoir.

Let's walk through the process of building both a present-tense and a passé composé sentence. We'll translate the English sentence "Marie went to school and she studied French" into correct French.

Even after you've memorized the conjugations and the DR MRS VANDERTRAMP list, certain situations trip students up repeatedly. The table below highlights the most common areas of confusion and shows you how to avoid them.

The passé composé is only the beginning of your journey with être and avoir as auxiliary verbs. As you advance in French, you'll discover that these same two verbs serve as the foundation for several other compound tenses. The table below previews how the auxiliary concept extends into more advanced grammar.

Notice the pattern: in every compound tense, the structure is always conjugated auxiliary + past participle. The only thing that changes is which tense the auxiliary is conjugated in. This means the work you're doing right now — memorizing which verbs take être, learning agreement rules, and forming past participles — will pay off repeatedly throughout your French studies. The passé composé is the template for all compound tenses to come.
