A copular verb (also called a linking verb) doesn't describe an action — it connects a subject to a description of itself. I am tired doesn't say what I'm doing; it tells you what state I'm in. The verb am is just the bridge between I and tired. French has a small but heavily-used set of copulas: être (the workhorse), devenir (to become), sembler and paraître (to seem), rester (to remain), demeurer (to remain, formal), se sentir (to feel), and the curious noun-based construction avoir l'air (to look, to seem).
The list is small, but each item has its own quirks — register, agreement behavior, subjunctive triggers, and where it stops being interchangeable with another. This page works through them in order of frequency and explains how French handles a job that English largely outsources to a single verb (to be) and a couple of helpers (to seem, to feel, to become).
être: the default copula
Être covers everything English handles with to be: identity, location, profession, time, condition, emotion. There is no ser/estar split as in Spanish, no essere/stare in the Italian sense. One verb does it all.
Je suis fatigué après cette semaine de fou.
I'm exhausted after this crazy week.
Marie est étudiante en médecine à Lyon.
Marie is a medical student in Lyon.
Il est tard ; on devrait rentrer.
It's late — we should head home.
Le restaurant est juste à côté de la pharmacie.
The restaurant is right next to the pharmacy.
The adjective or noun after the copula agrees with the subject in gender and number, exactly as it would in attributive position:
Sophie et Élise sont contentes du résultat.
Sophie and Élise are pleased with the result.
Mes parents sont retraités depuis l'année dernière.
My parents have been retired since last year.
A note on professions: French traditionally drops the indefinite article when the predicate is a profession with no qualifier (Marie est avocate, not Marie est une avocate). When you add a qualifier, the article comes back: Marie est une excellente avocate. This is unlike English, which always uses the article ("Marie is a lawyer").
devenir: to become
Devenir describes a change into a new state or identity. It is a 3e-groupe verb that conjugates exactly like venir and takes être in compound tenses (along with revenir, parvenir, intervenir, provenir, survenir — the venir-family verbs that describe motion or change of state). Note that tenir and most of its compounds (tenir, retenir, maintenir, obtenir, soutenir, contenir, appartenir) take avoir, not être. Like être, the predicate after devenir agrees with the subject.
Il est devenu médecin après dix ans d'études.
He became a doctor after ten years of studying.
Avec l'âge, elle est devenue beaucoup plus patiente.
With age, she's become much more patient.
A useful detail: French has a single word for "to become" (devenir), but English speakers sometimes try to translate phrases like "to make someone happy" or "to make something easier" with devenir. Those use a different verb, rendre: Cette nouvelle me rend triste ("this news makes me sad"). Devenir is what something or someone does on its own; rendre is what one thing does to another. Confusing the two is one of the most common A2-level errors and is treated in detail in the page on devenir vs rendre.
sembler and paraître: to seem
These two verbs are near-synonyms covering the work of English to seem and to appear. They are mostly interchangeable in modern French; paraître feels slightly more formal or literary.
Tu sembles inquiet — tout va bien ?
You seem worried — is everything okay?
Cette solution paraît trop simple pour être correcte.
This solution seems too simple to be correct.
The predicate agrees with the subject as expected:
Elle semble épuisée par le voyage.
She seems exhausted from the trip.
Les enfants paraissent ravis de nous voir.
The children seem delighted to see us.
Subjunctive trigger: a sembler/paraître subtlety
When sembler or paraître is used impersonally with que, the choice between subjunctive and indicative depends on whether the speaker is committed to the truth of the embedded clause. Compare:
Il semble qu'elle soit fatiguée.
It seems that she's tired. (subjunctive — speaker isn't asserting it as fact)
Il me semble qu'elle est fatiguée.
It seems to me that she's tired. (indicative — speaker is committing to the impression)
The personal me in il me semble que signals that the speaker is asserting their impression as a kind of weak fact, which licenses the indicative. The bare il semble que leaves the truth open and triggers the subjunctive. The same alternation exists with paraître.
This is one of the cleanest examples of how French uses the subjunctive to track speaker commitment, not just to mark a fixed list of triggers.
rester: to remain, to stay
Rester has two main jobs: a copular use ("to remain in a state") and a movement-style use ("to stay in a place"). The copular use links a subject to an adjective:
Il est resté calme malgré les critiques.
He stayed calm despite the criticism.
Cette question reste sans réponse depuis des années.
This question has remained unanswered for years.
In compound tenses, rester takes être (it's on the maison d'être list), and the participle agrees with the subject:
Mes cousines sont restées trois semaines à Paris.
My cousins stayed in Paris for three weeks.
There is also an existential use — il reste — meaning "there remain(s)" or "there is/are still":
Il reste deux parts de gâteau si tu en veux.
There are two pieces of cake left if you'd like one.
demeurer: to remain (formal)
Demeurer overlaps with rester but is markedly more formal or literary. In everyday speech it sounds out of place; in journalism, legal language, and elevated prose it is at home. Demeurer takes either être or avoir in compound tenses depending on meaning (être when copular/static, avoir when meaning "to dwell, reside") — though this distinction has eroded and avoir is now common across the board.
La question demeure sans réponse.
The question remains unanswered. (formal/literary)
Malgré les difficultés, l'espoir demeure intact.
Despite the difficulties, hope remains intact. (formal/literary)
se sentir: to feel
Se sentir is a pronominal verb used when the subject is the experiencer of a feeling or state. It's used for both physical and emotional states:
Je me sens un peu mieux ce matin.
I feel a bit better this morning.
Tu te sens bien ? Tu es tout pâle.
Are you feeling okay? You look pale.
Elle ne s'est jamais sentie aussi heureuse.
She's never felt so happy.
Note that the participle agrees with the subject through the reflexive pronoun, as with all pronominal verbs. Elle s'est sentie, ils se sont sentis, elles se sont senties.
There is a non-pronominal sentir meaning "to smell" (transitive: je sens une odeur de café) or "to feel something physically" (je sens le vent). It's a different verb from se sentir and shouldn't be confused with the copular use.
avoir l'air: to look, to seem
This is the strangest of the French copulas because it is built around a noun (air, "appearance"). It functions like sembler but adds a sense of visible appearance. Literally it would be "to have the air of [being something]."
Tu as l'air fatigué ce matin.
You look tired this morning.
Cette tarte a l'air délicieuse !
That tart looks delicious!
The agreement of the predicate adjective is the celebrated subtlety. There are two competing rules:
- Traditional rule: the adjective agrees with l'air (always masculine singular) — elle a l'air content.
- Modern rule: the adjective agrees with the subject — elle a l'air contente.
Both are accepted in current usage. Some speakers reserve the traditional agreement (with l'air) for cases where the appearance might be deceptive ("she has the look of someone happy, but..."), and the modern agreement (with the subject) for cases where the speaker takes the appearance at face value ("she really does look happy"). In practice, modern usage with subject agreement is universal in speech and increasingly dominant in writing. Both forms will be understood; pick the one your interlocutor uses.
Cette pomme a l'air mûre.
This apple looks ripe. (subject agreement, modern — common)
Cette pomme a l'air mûr.
This apple looks ripe. (l'air agreement, traditional — formal/literary)
When the subject is a person and the predicate adjective could only describe a person (not the abstract l'air), agreement with the subject is universal: elle a l'air enceinte ("she looks pregnant") — never enceint, because l'air can't be pregnant. Such cases force the modern reading.
Position of the predicate
In French, predicates after copulas come after the verb, exactly as in English:
Il semble heureux.
He seems happy.
There is no inversion or fronting required, except in marked literary or poetic contexts (Heureux qui, comme Ulysse...). For learners, "subject + copula + predicate" is a stable order.
Comparison with Spanish, Italian, and English
This is where French stands out among Romance languages. Spanish splits to be into ser (essence) and estar (state). Italian has essere / stare, with stare used for location, ongoing actions, and some temporary states. Portuguese likewise splits ser/estar.
French has only one copula for "to be": être. There is no temporary-vs-permanent split. Je suis content covers both "I am [generally] a happy person" and "I am happy [right now]." The distinction is made by context, time adverbs, or tense, not by verb choice. Je suis content de te voir (right now); j'ai toujours été content de ma vie (generally, in the past).
This is genuinely simpler than Spanish or Italian — French speakers do not have to make the ser/estar choice every time they describe a state. The trade-off is that French distinguishes être (general state) from se sentir (felt state), paraître (apparent state), avoir l'air (visible appearance), and devenir (incoming state) more carefully than English does. Learning when each is preferred is the work.
For an English speaker the only major hurdle is avoir l'air: nothing in English looks like "to have the air of." The phrase has no compositional meaning learners can lean on. Treat it as a unit and memorize a few stock examples (tu as l'air fatigué, ça a l'air bon, elle a l'air sympa) until it sounds natural.
Common Mistakes
❌ Marie est une médecin.
Incorrect — French drops the article before unmodified profession nouns.
✅ Marie est médecin.
Marie is a doctor.
❌ Cette nouvelle me devient triste.
Incorrect — devenir is intransitive (subject-internal change). Use rendre when something/someone causes a state in something/someone else.
✅ Cette nouvelle me rend triste.
This news makes me sad.
❌ Il semble qu'elle est fatiguée.
Incorrect — bare il semble que takes the subjunctive.
✅ Il semble qu'elle soit fatiguée.
It seems that she's tired.
❌ J'ai resté à la maison hier.
Incorrect — rester takes être in compound tenses.
✅ Je suis resté à la maison hier.
I stayed home yesterday.
❌ Elle se sent bien fatiguée ce soir.
Confusing structure — bien before an adjective is fine, but the more idiomatic phrasing is below.
✅ Elle se sent vraiment fatiguée ce soir.
She feels really tired tonight.
❌ Ce film a l'air intéressante.
Incorrect or marked — film is masculine, so the subject-agreement modern form would be intéressant.
✅ Ce film a l'air intéressant.
This movie looks interesting.
Key takeaways
- Être is the default copula and covers everything English handles with to be. French does not have ser/estar.
- Devenir describes a change into a new state; rendre describes one entity causing a state in another. They are not interchangeable.
- Sembler and paraître are largely interchangeable; impersonal il semble que triggers the subjunctive, while il me semble que takes the indicative.
- Rester takes être in compound tenses and lives on the maison d'être list.
- Demeurer is a formal/literary alternative to rester; use rester in everyday speech.
- Avoir l'air is unique in form; modern usage agrees the predicate with the subject (elle a l'air contente), traditional usage agrees with l'air (elle a l'air content). Both are correct.
- Drop the article before unmodified professions: Marie est avocate, not Marie est une avocate.
