French Irregular Verbs

French has a reputation for verb chaos that the numbers do not support. Around ninety per cent of French verbs end in -er and almost all of them are regular. What makes the language feel irregular is that the exceptions are the words you need in your first week.

The right approach is to sort them into groups. Very little in French irregularity is genuinely one of a kind.

The big four

These four are irregular in the present, in their participles and in their future stems. They are also the four most useful verbs in the language.

être (to be)avoir (to have)aller (to go)faire (to do, make)
/ j'
as
/ / ona
/

Three points worth holding onto:

  • and are the auxiliaries for every compound tense, so they turn up in nearly every past sentence.
  • builds the near future: (I am going to eat). Learning aller buys you a whole tense.
  • and are two of only three verbs in the language taking - rather than -ez in the vous form. The third is (dire).

The -ir split

This is the group that causes the most confusion, because -ir is really two families wearing the same coat.

Family 1: the type. Inserts -iss- in the plural. This is the larger group.

Personfinir
finissons
finissez
finissent

Also: choisir (to choose), réussir (to succeed), remplir (to fill), grandir (to grow), réfléchir (to think about).

Family 2: the type. No -iss-, and the final consonant of the stem drops in the singular.

Personpartir
part
partons
partent

Also: sortir (to go out), dormir (to sleep), servir (to serve), sentir (to feel), mentir (to lie).

Nothing in the infinitive tells you which family a verb belongs to. and are structurally identical and behave differently. This has to be learned verb by verb, and it is the one place in French verbs where there is no shortcut.

The -re verbs

Regular -re verbs (vendre, attendre, répondre, entendre) follow one pattern: -s, -s, -, -, -ez, -ent, with nothing at all in the third person singular. , not il vendt.

The irregular ones cluster usefully:

and its family (apprendre, comprendre) double the n in the plural:

  • je prends, tu prends, il prend, nous pren, vous prenez, ils prennent

and its family (permettre, promettre) double the t:

  • je mets, tu mets, il met, nous mettons, vous mettez, ils mettent

Others worth knowing individually: dire (je dis, vous ), lire (je lis, nous lisons), écrire (j'écris, nous écrivons), boire (je bois, nous buvons, ils boivent), croire (je crois, nous croyons).

The modal group

Four verbs behave alike and appear constantly, usually followed by an infinitive.

pouvoir (can)vouloir (want)devoir (must)savoir (know)

The first three share a shape: -x, -x, -t in the singular, then a stem change in the plural. is the odd one out with regular -s, -s, -t.

against is worth a note. Savoir is for facts and skills ( , I can swim). Connaître is for familiarity with people and places ( ).

Irregular past participles

These have to be memorised, but they are short and there are not many.

VerbParticipleVerbParticiple

carries a circumflex only in the masculine singular, to distinguish it from the article . The feminine is plain due.

Irregular future stems

The future is built by adding endings to the infinitive, so it is nearly always regular. A small set uses a modified stem, and the endings never change.

VerbFuture stemje form
ser-
aur-
ir-
-
viendr-
pourr-
voudr-
devr-
saur-
verr-
faudr-
enverr-

The same stems build the conditional (je serais, j'irais, je ferais), so this table earns its keep twice.

Worked examples

  • . (I am tired.) - être
  • . (We have three dogs.) - avoir
  • . (She goes to work.) - aller
  • . (It is cold.) - faire, in its weather use
  • à . (We finish at five.) - finir family
  • sortons . (We are going out tonight.) - partir family
  • . (I cannot come.) - pouvoir plus infinitive
  • J' train. (I took the train.) - irregular participle

Common mistakes English speakers make

The first is regularising the -ir plural: nous partissons instead of partons, or nous finons instead of . The two families have to be kept apart.

The second is using -ez for with , and : vous êtez, vous faisez, vous disez. It is , , .

The third is regularising past participles: j'ai voyé for j' , j'ai prendu for j' .

The fourth is regularising the future: je alleraí instead of j'. The stems in the table above are the only ones that change, but they are the verbs you reach for most.

The fifth is using for people: je sais Marie. Familiarity with a person is .

Frequently asked questions

What are the most important irregular verbs in French?
être, avoir, aller and faire, and it is not close. être and avoir are the two auxiliaries that build every compound tense, so they appear in almost every past sentence you will ever say. aller builds the near future (je vais manger). faire covers doing, making and a large set of weather and activity idioms. After those, pouvoir, vouloir, devoir, savoir, venir, prendre and dire carry most of the everyday load.
Are all French -ir verbs irregular?
No, but -ir hides two different families and that is what makes it feel irregular. The larger group follows finir and inserts -iss- in the plural: nous finissons, vous finissez, ils finissent. The smaller group follows partir and does not: nous partons, vous partez, ils partent. Both are internally regular. The difficulty is that the infinitive gives you no clue which family a verb belongs to, so it has to be learned per verb.
How many French verbs are irregular?
Roughly three hundred and fifty in common use, against several thousand regular -er verbs. The count understates the problem and overstates it at the same time: understates because the irregular ones are the most frequent verbs in the language, and overstates because they cluster into groups. Learn the groups on this page and the genuine one-offs come down to about ten verbs.
