Avoir (to have) · All tenses

French uses avoir (not être) for age, hunger, thirst, sleepiness, fear, heat/cold, and several other physical/emotional states: 'j'ai 20 ans' (I'm 20), 'j'ai faim' (I'm hungry), 'j'ai soif' (I'm thirsty), 'j'ai peur' (I'm afraid), 'j'ai chaud' (I'm hot), 'j'ai froid' (I'm cold). This is a major learner pitfall — English uses 'to be' for all of these.

Avoir is the everyday word for having anything (possession, age, states, characteristics). Posséder is more formal and emphasises ownership or possession in a stronger sense — used mostly for property, valuable assets, or legally-owned things: 'je possède une maison' (I own a house) vs 'j'ai une maison' (I have a house). In everyday speech, avoir wins; posséder is reserved for emphasis or formal contexts.

Use avoir as the auxiliary + the past participle 'eu' (pronounced like 'u'): j'ai eu, tu as eu, il/elle/on a eu, nous avons eu, vous avez eu, ils/elles ont eu. The participle 'eu' never changes form — no subject agreement with avoir as auxiliary.

Avoir's past participle 'eu' is one of the most contracted in French. It comes from Latin 'habutum' (had), which lost its consonants over centuries of phonetic erosion: habutum → eüt → eu. The 'eu' is pronounced like a single vowel sound — the same vowel as in 'peu' or 'feu'. Despite being two letters, it sounds like one syllable.

Both translate to 'j'ai eu' in the passé composé. French doesn't structurally distinguish present perfect from simple past — context disambiguates. For ongoing past possession ('I had been having'), use the imparfait 'j'avais'. For completed past possession at a specific moment, use the passé composé 'j'ai eu'.

The imparfait of avoir is: j'avais, tu avais, il/elle/on avait, nous avions, vous aviez, ils/elles avaient. Unlike être, avoir's imparfait stem 'av-' is derived regularly from the nous form 'avons' (drop -ons, add -ais/-ais/-ait/-ions/-iez/-aient). Avoir's only irregularities are in the present, passé composé, futur, and subjonctif — the imparfait is predictable.

Use 'j'avais' for ongoing past possession or states: 'j'avais un chat' (I had a cat — back then, ongoing). Use 'j'ai eu' for a completed past state with a clear boundary: 'j'ai eu un chat pendant cinq ans' (I had a cat for five years — bounded period). 'J'avais' also appears in 'il y avait' (there was/were — ongoing) and 'avoir + age' in the past ('il avait dix ans' = he was ten years old).

'Il y avait' is the imperfect form of 'il y a' (there is/are) — meaning 'there was / there were'. 'Il y avait beaucoup de monde' = 'There were lots of people'. Like its present-tense counterpart, 'il y avait' is invariable — doesn't agree with the number of things. The passé composé equivalent 'il y a eu' means 'there was (a specific event)': 'il y a eu un accident' (there was an accident — completed event). The contrast mirrors imparfait vs passé composé exactly.

The subjonctif présent of avoir is: que j'aie, que tu aies, qu'il/elle/on ait, que nous ayons, que vous ayez, qu'ils/elles aient. Singular forms + ils use 'ai-' (pronounced like the present 'ai'); nous/vous use 'ay-' with a 'y' for the diphthong. The stems are fully irregular.

Use it after triggers of necessity, will, doubt, emotion, or hypothesis: 'il faut que tu aies de la patience' (you need to have patience), 'je veux qu'il ait du temps' (I want him to have time), 'bien que nous ayons peur' (although we are afraid), 'avant que vous ayez fini' (before you finish — with 'aie' as auxiliary of subjonctif passé).

Visually, 'aie' has a final -e and 'ai' doesn't. Contextually, 'aie' appears after subjonctif triggers — typically 'que' clauses after verbs of doubt, emotion, will, or necessity. 'J'ai' (indicative) makes a statement; 'que j'aie' (subjonctif) appears in a subordinate clause expressing uncertainty or wish. Pronounced almost identically — the meaning comes from the sentence structure, not the form alone.

The futur of avoir uses the irregular stem 'aur-': j'aurai, tu auras, il/elle/on aura, nous aurons, vous aurez, ils/elles auront. The standard French future endings attach to 'aur-' rather than the infinitive 'avoir'. This same stem is reused for the conditionnel (j'aurais).

Avoir's futur stem is irregular and inherited from Latin 'habere' (to have) → vulgar Latin 'habere habeo' → 'auro' → French 'aur-'. The full infinitive 'avoir' would have been clumsy with future endings ('avoirai'). A handful of high-frequency French verbs developed contracted future stems through everyday speech: avoir (aur-), être (ser-), aller (ir-), faire (fer-), savoir (saur-), pouvoir (pourr-), vouloir (voudr-), venir (viendr-), devoir (devr-), voir (verr-).

Both express future possession. 'J'aurai' (futur simple) feels slightly more formal, more committed, or further in time: 'j'aurai vingt ans dans deux mois' (I'll be 20 in two months). 'Je vais avoir' (futur proche) is more conversational for near-term plans: 'je vais avoir un examen demain' (I'm going to have an exam tomorrow). The futur simple also expresses conjecture: 'elle aura raison' = 'she's probably right' — speculation about a likely present truth.

The conditionnel présent of avoir is: j'aurais, tu aurais, il/elle/on aurait, nous aurions, vous auriez, ils/elles auraient. The same irregular stem 'aur-' used in the futur, plus imperfect endings (-ais, -ais, -ait, -ions, -iez, -aient).

'J'aurais' is the standard French phrasing for polite requests: 'j'aurais besoin d'un café' (I would need a coffee = I'd like a coffee), 'j'aurais une question' (I have a question — softened). Compare with the more direct 'j'ai' (I have) — the conditionnel softens any request and is the default in shops, restaurants, and formal contexts. English speakers often under-use this softening structure.

'J'aurais + past participle' is the conditionnel passé (past conditional), meaning 'I would have + done X': 'j'aurais aimé venir' (I would have liked to come), 'tu aurais dû me le dire' (you should have told me — common with devoir). It expresses regret, missed opportunity, or hypothetical past: 'si j'avais su, je serais venu' (if I had known, I would have come). The structure: conditionnel of avoir/être + past participle.
