Ouvrir: an -ir verb that behaves like an -er verb.

Ouvrir means “to open”, and it is the best example in French of why the three verb families are a rough guide rather than a law. It ends in -ir, so it should take -is, -is, -it in the present. It does not. It takes -e, -es, -e, exactly like parler. Then, having been easy all the way through, it produces a past participle nothing predicts: ouvert.

Présent — -er endings on an -ir verb

The stem is ouvr- throughout — no changes, no boot — and the endings are the -er set. If you can conjugate parler, you can already conjugate this.

The five verbs that do this

Ouvrir, couvrir (to cover), découvrir (to discover), offrir (to offer, to give as a gift) and souffrir (to suffer). All -ir verbs, all taking -er endings in the présent, and all with a participle in -ert.

⚠ Don’t say j’ouvris

The finir pattern would give j’ouvris — and that form does exist, but it is the passé simple, a literary past tense. In speech it is j’ouvre.

Opening, offering and one false friend

The family is worth meeting together, because one of them means something learners consistently guess wrong.

FrenchMeans
j’ouvre la porte I open the door
ça ouvre à neuf heuresit opens at nineshops, museums
je t’offre un caféthe coffee’s on menot “I offer you” — it means to treat
offrir un cadeauto give a presentdonner is neutral; offrir is a gift
j’ai découvert que…I found out that…
Offrir is not “to offer”

It normally means to give as a present, or to pay for something for somebody. Je t’offre un verre is “I’ll get you a drink”, not a proposal. For the English sense of offering — putting a suggestion on the table — French uses proposer.

Passé composé — ouvert

Here is the irregularity. With avoir, the participle is ouvert — not ouvri, which is what the rest of the verb would lead you to expect. The whole family matches: couvert, découvert, offert, souffert.

FrenchEnglishListen
j’ai ouvertI opened / have opened
tu as ouvertyou opened / have opened
il / elle a ouverthe / she opened / have opened
nous avons ouvertwe opened / have opened
vous avez ouvertyou opened / have opened
ils / elles ont ouvertthey opened / have opened
It doubles as an adjective

Ouvert is also the word on the shop door, and it agrees like any adjective: la porte est ouverte, les magasins sont ouverts. The opposite is fermé.

Imparfait — regular

From ouvrons: j’ouvrais. Nothing unusual.

FrenchEnglishListen
j’ouvraisI used to open / was opening
tu ouvraisyou used to open / was opening
il / elle ouvraithe / she used to open / was opening
nous ouvrionswe used to open / was opening
vous ouvriezyou used to open / was opening
ils / elles ouvraientthey used to open / was opening

Futur and conditionnel — the full infinitive

Unlike -re verbs, nothing is dropped: the stem is the whole infinitive, ouvrir-, giving j’ouvrirai. Two rs and an i between them — worth writing out once.

FrenchEnglishListen
j’ouvriraiI will open
tu ouvrirasyou will open
il / elle ouvrirahe / she will open
nous ouvrironswe will open
vous ouvrirezyou will open
ils / elles ouvrirontthey will open

Conditionnel — would open

J’ouvrirais. The polite request built on it is one you will use: pourriez-vous ouvrir la fenêtre ?

FrenchEnglishListen
j’ouvriraisI would open
tu ouvriraisyou would open
il / elle ouvriraithe / she would open
nous ouvririonswe would open
vous ouvririezyou would open
ils / elles ouvriraientthey would open

Subjonctif — identical to the présent

Because the présent already takes -e endings, four of the six subjunctive forms are spelled exactly like the présent. Only nous and vous differ.

FrenchEnglishListen
j’ouvre(that) I open
tu ouvres(that) you open
il / elle ouvre(that) he / she open
nous ouvrions(that) we open
vous ouvriez(that) you open
ils / elles ouvrent(that) they open

Impératif — no s

Because it behaves like an -er verb, the tu imperative drops its s: ouvre !, not ouvres. Compare pars ! and mets !, which keep theirs.

FrenchEnglishListen
ouvre !open! (to one person you know)
ouvrons !let’s open!
ouvrez !open! (formal, or to a group)

Plus-que-parfait — had opened

J’avais ouvert.

il / elle avait ouverthe / she had opened
nous avions ouvertwe had opened
vous aviez ouvertyou had opened

Quick answers

Ouvrir, answered.

The questions that come up while you are learning the table.

How do you conjugate ouvrir in the present tense?+
J’ouvre, tu ouvres, il / elle ouvre, nous ouvrons, vous ouvrez, ils / elles ouvrent. It takes -er endings despite the -ir infinitive.
Why does ouvrir use -er endings?+
It is a small closed group left over from Latin: ouvrir, couvrir, découvrir, offrir and souffrir. There is no rule to derive it from — the five are simply learnt together.
What is the past participle of ouvrir?+
Ouvert, with avoir. The family follows: couvert, offert, souffert.
What is the imperative of ouvrir?+
Ouvre (to one person), ouvrons, ouvrez. The tu form has no s, because the verb takes -er endings.
Does offrir really mean “to offer”?+
Usually not. Offrir means to give as a present or to pay for something for someone — je t’offre un café is “the coffee’s on me”. For the English sense of proposing something, use proposer.
