12 Must-Know Regular -Ir Verbs and How to Use Them with Ease

Without verbs, we couldn’t do… well, anything.

We could only point at things and yell nouns and adjectives.

But you probably already knew that verbs were essential to language, and therefore, to learning French.

Well then, what’s the problem? Let’s start conjugating! It’ll be your favorite thing.

Or not. Regardless, if you’re serious about learning French, you need to learn to love your verbs.

Once you master conjugating them, you can move onto the finer things in life: caviar, watching French movies, reading French novels, and even… drumroll… speaking French! (That’s the goal here, right? Or am I in the wrong place?)

So today I’m going to break down one entire group of French verbs for you: regular -ir verbs.

Quick Crash Course: What, for Pete’s (Pierre’s) Sake, Is a Regular -Ir Verb?

In French, there are three groups of verbs:

Le premier groupe (First Group): Verbs that end in -er, like parler (to talk).

Le deuxième groupe (Second Group): Verbs that end in -ir (the verbs in question), like partir (to leave).

Le troisième groupe (Third Group): All other verbs, usually irregular, and verbs that end in -re, like attendre (to wait).

So, -ir verbs are one of three amazing groups of French verbs. I’m sure that you’ll get around to all three, but for now, we’ll stick with one group.

What makes them regular? They show up the most? They dress casually? They get their fiber?

No, none of that. When a verb is regular, it means that it follows a simple formula for conjugation. Irregular verbs, on the other hand, are rebels. They play by their own rules.

In short, regular verbs are the easiest ones to conjugate!

Conjugation Station: The Past, Present and Future of -Ir Verbs

The infinitive (the un-conjugated verb) doesn’t do you much good. Sure, you’ll need it for the near-future (“I am going to” + infinitive) and other grammar constructions. But at the crux of a verb’s usage, is the ability to conjugate and accommodate to different subjects and tenses.

Present Tense

For all regular present tense verbs (irregulars aside!), there are basic endings you tack on to the stem, based on who’s performing the action described by the verb. If you aren’t familiar with the terms, don’t worry, we’ll break it down with the example of bâtir (to build):

The stem for any regular -ir verb will be the infinitive (bâtir), with the –ir chopped off and thrown into the trash can. That leaves us with the stem:


Now that we have the stem, we add our present tense endings based on who’s performing the action described by the verb:


Je… -is
Tu… -is
Il/Elle/On… -it
Nous… -issons
Vous… -issez
Ils/Elles… -issent

So then, all together now with our example bâtir!

Je bâtis (I build) 
Tu bâtis (You build)
Il/Elle bâtit (He/She builds)
Nous bâtissons (We build)
Vous bâtissez (You build)
Ils/Elles bâtissent (They build)

And that will work for all of the regular -ir verbs! Every. Last. One.

Imperative Mood

I like to call the imperative mood the “bossy pants mood,” because it’s used to give commands to people. Let’s use the example of abolir (to abolish) to show the three different forms of the imperative mood:

There are the tu, nous and vous forms of the imperative mood. Depending on who you’re commanding or expressing a wish to, you will use one of these forms. Only, you won’t use the pronoun. Think of the English imperative: “Sit down!” “Make me coffee!” “Leave!”

It’s the same idea, but with different conjugations depending on who you’re talking to:


(tu) -is
(nous) -issons
(vous) -issez

Notice that they’re the same as the present tense. So if we conjugate abolir, we get:

Abolis les chapeaux rouges !
(Abolish red hats!)

Abolissons les légumes verts !
(Let’s abolish green vegetables!)

Abolissez les devoirs !
(Abolish homework!)

You get the picture. Again, this will work with any old regular -ir verb in the book.

Perfect Tense

Regardless if you have delved into the past or not (if not, then the link above will give you a great overview of this past tense), it’s good to be familiar with the endings.

Since the perfect tense is a compound tense—first made up of avoir or être conjugated to the subject in the present tense, plus what we like to call the “past participle,”—it’s important to know both how to conjugate avoir and être, as well as what the past participles are for each verb. Let’s use guérir (to cure/heal) as an example:

With any regular -ir verb, you start with the stem (by chopping off the -ir part) to find the past participle:

So guérir becomes guér- 

Then, you add the ending for the past participle (which is the same no matter what your regular -ir verb is): –i

Which makes your past participle: guéri 

Then, whether you’re using the past participle for the perfect tense, or another compound tense (go you!), you place the past participle after the conjugated verb, like so:

J’ai guéri (I healed)
Tu as guéri (You healed)
Il/Elle a guéri (He/She healed)
Nous avons guéri (We healed)
Vous avez guéri (You healed)
Ils/Elles ont guéri (They healed)

You can also think of this as simply cutting off the -r on the infinitive in order to get your past participle!

Imperfect Tense

Another past tense! (And once again, you can learn or review the tense by following the link above). The imperfect (no less perfect than the perfect tense), is used to describe past events that spanned a longer period of time, are related to emotion, or happened before another past event. Actually, learning when to use the imperfect tense is the real challenge, conjugating it for regular -ir verbs is a breeze.

We’ll use the verb grossir (to get fat/gain weight) as an example.

You start by conjugating the nous form of the verb (remember that you find the stem by cutting off the -ir, then add –issons).

This leaves us with grossissons.

Warning: Do not be alarmed by the insane amount of s’s. It happens with -ir verbs sometimes! Just follow the rules and I promise you’ll get it right.

So now that you have the nous form, you cut off the -ons part (just that part), which leaves us with grossiss- 


Then, you add the imperfect ending:

Je… –ais
Tu… –ais
Il/Elle/On… –ait
Nous… –ions
Vous… –iez
Ils/Elles… –aient 

Mix it all together with our stem grossiss-, and you get:

Je grossissais (I was putting on weight)
Tu grossissais (You were putting on weight)
Il/Elle grossissait (He/She was putting on weight)
Nous grossissions
(We were putting on weight)
Vous grossissiez
(You were putting on weight)
Ils/Elles grossissaient
(They were putting on weight)

No matter how many s’s in your verb, this will work every time with regular -ir verbs!


You likely guessed by the name of the tense, that it’s used to talk about events that will happen in the future. You’re right! If you want a more in-depth discussion on how and when to use the future tense, follow the link above.

Now this one really is the easiest to conjugate (I’m not just saying that so you’ll keep reading!). In fact, it doesn’t matter if the verb in question is a regular -ir verb or regular -er verb, it’s the same method:

Let’s use maigrir (to lose weight) as an example:

To find the stem, you do nothing. With regular -ir and -er verbs, the stem is the infinitive! Yay!


Then, you add the future endings:

Je… -ai
Tu… -as
Il/Elle/On… -a
Nous… -ons
Vous… -ez
Ils/Elles… -ont 

Throw it all together and you get:

Je maigrirai (I will lose weight)
Tu maigriras (You will lose weight)
Il maigrira (He will lose weight)
Nous maigrirons (We will lose weight)
Vous maigrirez (You all will lose weight)
Ils maigriront (They will lose weight)

So let’s all join a gym! (Just kidding.)

Where and How to Study Up on Regular French -Ir Verbs

You retained all of that, right? Okay, so if not, there are tons of fun ways to study verbs (especially -ir verbs).

  • QuizletIf you haven’t already been using Quizlet to challenge your knowledge and whirl yourself up into a flashcard frenzy, then you’re missing out big time. Here’s a link to a great list of regular -ir verbs. If you need to work on vocabulary and definitions, then this a great place to try out flashcards, play games and practice your spelling!
  • is exactly what it sounds like, another great resource that will guide you through language learning. It has access to good French reading material, vocabulary and grammar modules. For our purposes, here’s a great activity to practice conjugating regular -ir verbs, if that’s where you find the struggle to be real.
  • Conjuguemos: Let me level with you, conjugation may be where the struggles lie. Conjuguemos is a great resource to have bookmarked throughout your life as a Francophile. Whatever your trouble may be—subjunctive, past tense, future, compound tenses galore—there are customizable conjugation activities for each. The site also includes vocabulary practice and more grammar than we can handle. To see how you fair with those -ir verbs, here’s a link to their turf.
  • Index cards. Yes, there are some of us who really do enjoy caressing note cards and color coding our vocabulary words! For -ir verbs, or any type of verbs, there’s a great system to study with nothing more than a pack of index cards and some colored markers. You’ll need to make three piles of index cards:

First pile: the infinitives of regular -ir verbs on one side, and their definitions on the back.

Second pile: the names of all the tenses you know so far (present, future, perfect, imperfect, subjunctive, etc.)

Third pile: pronouns, including je, tu, il/elle, nous, vous, ils/elles.

Then shuffle them up, pick one from each pile and do the appropriate conjugation. If you picked choisir from one pile, present tense from the second and je from the third pile, then your answer would be je choisis. 

Don’t let anyone tell you that flashcards aren’t amazing and magical!
