Irregular Verbs French Learners Need to Know

Mastering French verbs is essential for anyone learning the language. While regular verbs follow predictable conjugation patterns, irregular verbs in French can be tricky because they don’t always follow the rules. This guide will help you understand what makes a verb irregular, introduce the most common irregular verbs, and provide strategies to learn French effectively through immersion and practice.

What Are Irregular Verbs in French?

How irregular verbs differ from regular verbs

In French, regular verbs like most -er and regular -ir verbs follow predictable present tense endings and past tense patterns. Irregular verbs, on the other hand:

Stem changes

Often change their stem depending on the subject.

Unique endings

May have unique endings that don’t follow the standard patterns.

Different verb groups

Can belong to -er, -ir, or -re groups, but behave differently.

For example, the verb avoir (to have) is irregular because its forms in the present tense are:

Subject	Conjugation (Present Tense)
je	ai
tu	as
il/elle/on	a
nous	avons
vous	avez
ils/elles	ont

This irregularity makes French grammar more complex but also more expressive.

Why learning irregular verbs is essential

Irregular verbs are among the most frequently used verbs in French. Learning them is crucial because:

They appear in everyday conversation.
They are essential in reading, writing, and listening comprehension.
Knowing irregular verbs allows you to build correct sentences across all tenses.

Without mastering them, your French language skills will be incomplete.

Common Irregular Verbs in French

Most frequent irregular ER, IR, and RE verbs

Here’s a list of common irregular verbs in French, including English translation and pronunciation:

French Verb	English	Pronunciation
être	to be	etr
avoir	to have	ah-vwar
aller	to go	ah-lay
venir	to come	vuh-neer
faire	to do / make	fehr
prendre	to take	prahndr
pouvoir	can / to be able to	poo-vwar
devoir	must / to have to	duh-vwar

These verbs are irregular in different ways: some change stems, others have unique endings, and many are commonly used in both spoken and written French.

Examples in everyday sentences

Je viens à l’école tous les jours. (I come to school every day.)

Tu as un livre intéressant. (You have an interesting book.)

Nous faisons nos devoirs après le dîner. (We do our homework after dinner.)

Ils voient le professeur. (They see the teacher.)

Il doit partir maintenant. (He must leave now.)

Conjugation Tips for Irregular French Verbs

Present tense patterns and exceptions

Unlike regular verbs, irregular verbs often require memorizing their stems:

Some -ir verbs like venir and tenir have stem changes (je viens / nous venons).
Certain -re verbs like prendre change their final consonant in singular forms (je prends / nous prenons).
High-frequency verbs like être and avoir have completely unique forms.

Example: Present tense of “venir”

Subject	Stem	Ending	Conjugation
je	vien	s	viens
tu	vien	s	viens
il/elle	vien	t	vient
nous	ven	ons	venons
vous	ven	ez	venez
ils/elles	vienn	ent	viennent

Past, future, and subjunctive forms

Passé composé

Passé composé: Most irregular verbs use avoir or être + past participle (j’ai fait, il est venu).

Future tense

Future tense: Add endings to the irregular stem (je pourrai, nous devrons).

Subjunctive

Subjunctive: Stem changes are common (que tu viennes, qu’il fasse).

Understanding these patterns allows you to use irregular verbs correctly across all tenses.
