Irregular -er Verbs in French: Aller, Envoyer, and the Almost-Regular Rest

French has exactly one genuinely irregular -er verb: aller. Everything else in -er keeps the standard endings and only adjusts its stem, which is why grammars usually treat envoyer, acheter, appeler, and préférer as almost-regular rather than irregular.

Je vais au marché, et j'envoie le colis en rentrant.

I'm going to the market, and I'll send the parcel on the way back.

What it is

Calling a verb irregular normally means its endings misbehave. By that test the -er group has one member: aller, which uses three unrelated stems in the present and a fourth in the future. Every other -er verb keeps -e, -es, -e, -ons, -ez, -ent and merely rewrites part of its stem to protect a sound.

aller → je vais, tu vas, il va, nous allons, vous allez, ils vont. — to go → I go, you go, he goes, we go, you go, they go.

How to spot it

Ask whether the endings are intact. If they are, the verb is regular and something in the stem is simply being spelled differently; if they aren't, you're looking at aller.

  • Nous allons à la plage. — We're going to the beach. (aller: truly irregular)
  • J'envoie une carte postale. — I'm sending a postcard. (envoyer: stem only)
  • Elle achète du pain. — She's buying bread. (accent change only)
  • Nous plaçons les chaises. — We're arranging the chairs. (spelling only)

This is good news: the largest verb group in French has essentially one exception, and you'll have learned it in your first week.

Common Irregular -er Verbs Examples in French

The verbs that are usually filed under this heading:

Aller in the Present

Je vais bien, merci.
I'm fine, thanks.
Tu vas où comme ça ?
Where are you off to?
On va au cinéma ce soir.
We're going to the cinema tonight.
Ils vont rentrer tard.
They're going to get home late.

Ça va is built from this verb and is probably the most-used sentence in spoken French.

Envoyer and Its Family

J'envoie le dossier ce matin.
I'm sending the file this morning.
Nous envoyons les invitations demain.
We're sending the invitations tomorrow.
Ils renvoient le formulaire signé.
They're sending back the signed form.
Je t'enverrai les détails.
I'll send you the details.

The present is ordinary; only the future is unpredictable. Enverrai has a double r, like verrai and pourrai.

Stems That Shift Their Accent

J'achète le journal chaque matin.
I buy the paper every morning.
Elle appelle sa sœur le dimanche.
She calls her sister on Sundays.
Nous préférons partir tôt.
We'd rather leave early.
Ils jettent les vieux papiers.
They're throwing out the old papers.

The change happens in je, tu, il, and ils, and disappears in nous and vous. Those two forms keep the infinitive's spelling.

Stems That Protect a Sound

Nous commençons à comprendre.
We're beginning to understand.
Nous voyageons souvent en train.
We often travel by train.
Je paie par carte.
I'm paying by card.
Il nettoie la cuisine.
He's cleaning the kitchen.

Nothing about the pronunciation changes here. The spelling changes precisely so that it doesn't.

How the -er Exceptions Work

One verb is a genuine outlier. The rest follow a single logic: French rewrites a stem whenever an ending would otherwise change how it sounds.

Aller Has Three Present Stems

Vais, vas, va come from one Latin verb, allons and allez from another, and vont from a third. French merged them, and the result is the only -er verb whose forms can't be predicted from its infinitive.

Je vais, nous allons, ils vont.

I go, we go, they go.

va- / all- / vont.

Aller's Future Stem Is ir-

It's the shortest future stem in the language: j'irai, tu iras, il ira. The conditional uses the same stem, giving j'irais, so a single syllable covers two tenses.

J'irai en Bretagne cet été.

I'll go to Brittany this summer.

aller → ir- → j'irai.

Envoyer Is Regular Until the Future

In the present, envoyer follows the -yer rule and gives j'envoie, nous envoyons. Its future, however, is enverr-, which no rule predicts. Renvoyer inherits the same stem.

Nous vous enverrons une confirmation.

We'll send you a confirmation.

j'envoie, but j'enverrai.

The Stress Explains the Stem Changes

Endings -e, -es, and -ent are silent, so the stress lands on the stem and the vowel in it opens up. French marks that with a grave accent (j'achète, je préfère) or a doubled consonant (j'appelle, je jette). In nous and vous the ending is audible, so nothing changes.

Tu répètes la phrase, nous répétons ensemble.

You repeat the sentence, we repeat it together.

Silent ending, stressed stem, changed spelling.

Spelling Changes Are Not Sound Changes

Nous mangeons keeps an e and nous commençons takes a cedilla so that g and c stay soft before o. These verbs are not irregular at all: they're regular verbs written carefully.

Nous lançons le projet en septembre.

We're launching the project in September.

ç and ge before a and o.

Common Mistakes with Irregular -er Verbs

Incorrect: Je alle au travail en bus. — I go to work by bus.

Correct: Je vais au travail en bus. — I go to work by bus.

Aller looks like a regular -er verb and isn't. Its singular forms are built on va-, not on all-, which only appears in nous allons and vous allez.

Incorrect: Ils allent au restaurant. — They're going to the restaurant.

Correct: Ils vont au restaurant. — They're going to the restaurant.

The third-person plural is vont, one of the four verbs in French that take -ont in the present: sont, ont, vont, font.

Incorrect: J'envoierai le contrat lundi. — I'll send the contract on Monday.

Correct: J'enverrai le contrat lundi. — I'll send the contract on Monday.

Envoyer is the one -yer verb that doesn't build its future on the infinitive. Its stem is enverr-, with two r's, and payer or nettoyer offer no guidance here.

Incorrect: Nous achètons du fromage. — We're buying cheese.

Correct: Nous achetons du fromage. — We're buying cheese.

The grave accent appears only where the ending is silent. Nous and vous have audible endings, so the stem goes back to the spelling of the infinitive.

Aller and Envoyer Across the Tenses

Aller is worth conjugating in full, because it is both an ordinary verb and a piece of French grammar. Envoyer is here for its future stem, the one form that has to be memorised.

Aller in the indicative

The present is unpredictable; the imperfect, future, and compound past are all perfectly orderly once you know that the imperfect stem is all- and the future stem is ir-.

Pronounprésentimparfaitfuturpassé composé
je / j'vaisallaisiraisuis allé(e)
tuvasallaisirases allé(e)
il / elle / onvaallaitiraest allé(e)
nousallonsallionsironssommes allé(e)s
vousallezalliezirezêtes allé(e)(s)
ils / ellesvontallaientirontsont allé(e)s

Aller takes être in the compound past, so the participle agrees: elle est allée, elles sont allées.

Aller in the subjunctive and the imperative

The subjunctive adds a fourth stem, aill-, which appears wherever the ending is silent. The imperative is short and used constantly.

Pronounsubjonctifconditionnelimpératif
je / j'que j'ailleirais
tuque tu aillesiraisva
il / elle / onqu'il ailleirait
nousque nous allionsirionsallons
vousque vous allieziriezallez
ils / ellesqu'ils aillentiraient

The tu imperative is va, but it becomes vas before y: vas-y, go on.

Envoyer, where only the future is odd

The present follows the -yer rule (y becomes i before a silent ending) and the imperfect is completely regular. The future and conditional use enverr-.

Pronounprésentimparfaitfuturconditionnel

vousenvoyezenvoyiezenverrezenverriez
ils / ellesenvoientenvoyaientenverrontenverraient

Nous envoyions in the imperfect has two i's: one from the stem, one from the ending. It looks wrong and is correct.

Aller as a Piece of Grammar

Aller is irregular partly because it works so hard. Besides meaning to go, it builds a tense, reports on health, and carries a set of fixed expressions.

The near future

Aller plus an infinitive is the everyday way of talking about what will happen. In conversation it has largely displaced the simple future for anything imminent or already arranged.

Je vais te rappeler ce soir.
I'll call you back tonight.
Il va pleuvoir.
It's going to rain.
Nous allons déménager en juin.
We're going to move house in June.

In the imperfect this becomes the past intention: j'allais partir, I was about to leave.

Health, fit, and suitability

Aller reports how someone is, whether clothes suit them, and whether an arrangement works. English uses three different verbs for these.

Comment allez-vous ?
How are you?
Cette veste te va très bien.
That jacket suits you very well.
Mardi, ça vous va ?
Does Tuesday work for you?

Ça va answers all three and is the single most flexible phrase in spoken French.

Fixed expressions

A handful of very common phrases are built on aller and don't decompose into their parts, so they're best met whole.

Allons-y !
Let's go!
Ça va de soi.
That goes without saying.
Il y va de ta santé.
Your health is at stake.
Vas-y doucement.
Take it easy.

S'en aller, to go away, is the pronominal cousin: je m'en vais, va-t'en.

Irregular -er Verbs FAQs

Which -er verbs are irregular in French?
Strictly speaking only aller, whose present tense uses three stems (je vais, nous allons, ils vont) and whose future stem is ir-. Envoyer is the runner-up: its present is regular but its future is enverrai. Everything else in -er keeps the standard endings.
Is acheter an irregular verb?
No. J'achète takes a grave accent because the ending is silent and the stem carries the stress, but the endings themselves are the normal -e, -es, -e, -ons, -ez, -ent. In nous achetons the accent disappears and the verb looks entirely ordinary.
Why is aller irregular?
Because it was assembled from three separate Latin verbs. Vais and vas descend from vadere, allons and allez from a form related to ambulare, and vont from a fourth source. French kept whichever form was most common in each person.
What is the future of envoyer?
J'enverrai, tu enverras, il enverra, nous enverrons, vous enverrez, ils enverront. The stem is enverr-, with a double r that is pronounced. Renvoyer follows it: je renverrai.
Does aller take avoir or être in the past?
Être, with agreement on the participle: je suis allé, elle est allée, ils sont allés, elles sont allées. Its pronominal form s'en aller does too: elle s'en est allée.
