Avoir: Complete Paradigm Reference

This is the complete paradigm reference for avoir — every simple tense, every compound tense, every mood, including the literary forms (eus, eût, eussent, eût eu) that you will rarely produce but must recognize when reading. The everyday treatment of avoir — possession, the auxiliary role, the sensation idioms, the il y a construction — lives at verb-reference/avoir. This page is for the moments when you need to look up a form, including the obscure ones.

Avoir is the second-most-frequent verb in French and one of the two pillars of the language (with être). Its paradigm is wildly irregular because it descends from a single Latin root that underwent extreme phonetic erosion: Latin habēre lost its initial h, lost its medial b, and shrank to forms that look nothing like the infinitive. The result is a paradigm with five distinct stems — ai-/a-, av-, aur-, eu-, and ay-/ai- — that you must learn as separate paradigms rather than try to derive from avoir.

Etymology: Latin habēre eroded to fragments

French avoir descends from Latin habēre ("to have, to hold"), which followed the same erosion pattern that shaped its Romance siblings (haber, avere).

The takeaway: there is no underlying constant root. The Latin h was already silent in late Latin and was dropped from spelling; the b lenited to v (giving av-), then disappeared entirely in some forms (ai, ont); the perfect stem habu- contracted to eu- (the spelling is medieval and preserves the lost e); the futur aurai descends from a Vulgar Latin construction habēre + habeo ("I have to have") that fused into a single inflected form. Each stem must be memorized as its own paradigm.

Simple tenses: complete paradigms

Présent de l'indicatif

The most-used tense — three stems (ai-, a-, ont) plus the av- of the plural. Note the obligatory liaisons in 1pl, 2pl, 3pl.

The contrast ils sont /il sɔ̃/ vs ils ont /il‿zɔ̃/ is one of the most consequential pronunciation distinctions in spoken French — the only audible signal that distinguishes "they are" from "they have" is the liaison /z/ inside ils ont. Mishearing this is a constant source of beginner confusion.

Imparfait

Built on the av- stem (from nous avons) plus the regular imparfait endings -ais, -ais, -ait, -ions, -iez, -aient. Fully predictable.

Passé simple (literary)

Used in literary writing, biographies, and historical narration — almost never spoken. The stem is eu-, pronounced /y/ throughout.

The circumflex on eûmes and eûtes is obligatory — it marks the long vowel and historically descends from a lost -s- (medieval eu(s)mes). The 1990 spelling reform makes the circumflex optional on i and u in many words, but it is kept on the 1pl/2pl of the passé simple and subjonctif imparfait to disambiguate from other forms.

Futur simple

Stem aur- (irregular — does not derive from the infinitive avoir). Endings are the regular futur endings -ai, -as, -a, -ons, -ez, -ont.

Conditionnel présent

Same stem aur- as the futur, with imparfait endings.

The aurais / aurai contrast (conditionnel vs futur) is a frequent stumbling block — the conditionnel adds a final /ɛ/ where the futur has /e/, and writers often confuse the spellings. The mnemonic: 1sg conditionnel always ends in -ais, 1sg futur always ends in -ai.

Subjonctif présent

Two stems: ai- (1sg, 2sg, 3sg, 3pl) and ay- (1pl, 2pl). The forms aie, aies, ait, aient are all four pronounced /ɛ/ — homophones distinguished only in writing.

Subjonctif imparfait (literary)

Used in formal literature for the past subjunctive in subordinate clauses governed by a past-tense main verb. Almost completely absent from spoken French; modern writing replaces it with the present subjunctive.

The 3sg eût takes a circumflex — without it, the form would be eut, the passé simple. The circumflex is the only orthographic distinction between the two paradigms in the third-person singular. This circumflex is one of the most carefully observed in modern French publishing — failing to write eût where the subjunctive imparfait is required is treated as a serious editorial error.

Impératif

Three forms, taken from the subjunctive stem (not the indicative). Rare in everyday speech but obligatory in fixed expressions and elevated style.

Participles and gérondif

The participle eu is one of the strangest spellings in French — three written letters representing a single sound /y/. The spelling reflects the medieval form eüt with a diaeresis on the u; the diaeresis fell away in modern spelling but the silent e remained. The same eu spelling pronounced /y/ appears throughout the passé simple and subjonctif imparfait (eus, eut, eût, eussent) — not to be confused with the diphthong eu /ø/ in words like peu, deux, bleu.

Compound tenses: complete paradigms

Avoir uses avoir (itself!) as its own auxiliary in compound tenses. This is the natural case — only the maison-d'être motion verbs and reflexives take être. The participle eu never agrees with the subject in avoir-auxiliary tenses; it agrees only with a preceding direct object.

Passé composé

avoir (présent) + eu

In speech, ai eu and as eu are often heard as /e.y/ and /a.y/ — a vowel cluster that beginners may mishear as a single sound. There is no liaison between ai and eu.

Plus-que-parfait

avoir (imparfait) + eu

Passé antérieur (literary)

avoir (passé simple) + eu

This is one of the rarest forms in the language — avoir as auxiliary of itself in the literary past anterior. You will encounter it almost exclusively after temporal conjunctions (dès qu'il eut eu...) in 19th-century novels.

Futur antérieur

avoir (futur) + eu

Conditionnel passé

avoir (conditionnel) + eu

Subjonctif passé

avoir (subjonctif) + eu

Plus-que-parfait du subjonctif (literary)

avoir (subjonctif imparfait) + eu

This form is also called the deuxième forme du conditionnel passé when it functions as a literary substitute for the conditionnel passé in the apodosis of a hypothetical (il l'eût eue plus tôt s'il avait demandé). In modern French it survives mostly as a stylistic flourish in the most formal writing.

Pronunciation notes

Three points are worth memorizing.

1. Liaison /z/ in 1pl, 2pl, 3pl present. Nous avons /nu‿zavɔ̃/, vous avez /vu‿zave/, ils ont /il‿zɔ̃/. The s of the pronoun is silent in isolation but resurfaces as /z/ before the vowel-initial verb. The ils ont /il‿zɔ̃/ vs ils sont /il sɔ̃/ contrast hangs on this single /z/.

2. The participle eu is /y/, a single vowel. Three written letters, one sound. The same applies to all passé simple forms: eus, eut /y/, eûmes /ym/, eûtes /yt/, eurent /yʁ/. Never pronounce eu as the diphthong /ø/ here.

3. The subjunctive forms aie, aies, ait, aient are all /ɛ/. Four homophones in the paradigm — context (and writing) disambiguates. Ayons and ayez break the pattern with /ɛ.jɔ̃/ and /ɛ.je/ — the y introduces a /j/ glide.

Comparison with English

Three friction points worth restating in a paradigm reference.

1. Compound tenses use avoir itself as auxiliary. J'ai eu — literally "I have had." English have had uses have for both pieces; French does the same with avoir + eu. Once you internalize this, the compound paradigms become symmetric: every avoir-auxiliary verb works the same way.

2. The participle eu doesn't agree with the subject. Ils ont eu de la chance, never ils ont eus. With avoir as auxiliary, the participle agrees only with a preceding direct object — la chance qu'ils ont eue, not the subject.

3. The subjunctive matters even for avoir. Trigger contexts (il faut que, je veux que, bien que) shift avoir into its subjunctive paradigm: il faut que tu aies, never il faut que tu as. English has no parallel — "you have to have" stays in the same form throughout.

Common Mistakes

Mistake 1: Confusing aurais and aurai in writing.

Mistake 2: Spelling eut without circumflex when the subjunctive imparfait is required.

Mistake 3: Pronouncing eu as /ø/ instead of /y/.

Mistake 4: Using que tu as instead of que tu aies.

Mistake 5: Agreeing the participle eu with the subject.

Key takeaways

Avoir has five distinct stems that you must learn as separate paradigms: ai-/a- (présent sg), av- (présent pl, imparfait, infinitif), aur- (futur, conditionnel), eu- (passé simple, participe), ai-/ay- (subjonctif). The historical reason is severe phonetic erosion of Latin habēre; the practical consequence is that you cannot derive forms from a single root — each stem is its own paradigm to memorize.

The participle eu is pronounced /y/ — a single vowel, three letters. The same /y/ runs through the entire passé simple and subjonctif imparfait. The 3sg eût carries an obligatory circumflex that distinguishes it from the passé simple form eut.

In compound tenses, avoir uses avoir as its own auxiliary: j'ai eu, j'avais eu, j'aurai eu. The participle never agrees with the subject in this construction; agreement happens only with a preceding direct object (la patience qu'il a eue).
