French conjugation


Conjugation is the variation in the endings of verbs depending on the person, tense and mood. Most French verbs are regular and their inflections can be entirely determined by their infinitive form.
French verbs are conventionally divided into three groups. The first two are the -er and -ir conjugations. Verbs of the first two groups follow the same patterns, largely without exception. The third group displays more variation in form.
The third group is a closed class, meaning that no new verbs of this group are created. Most new verbs are of the first group, with some in the second group.
In summary the groups are:
  • 1st conjugation: verbs ending in -er. There are about 6000 verbs in this group.
  • 2nd conjugation: verbs ending in -ir, with the present participle ending in -issant. There are about 300 verbs in this group.
  • 3rd group: All other verbs: verbs with infinitives in -re, -oir, -ir with the present participle ending in -ant, the verb aller.

    Verb forms

The verb forms of French are the finite forms, which are combinations of grammatical moods in various tenses, and the non-finite forms. The moods are:
indicative,
subjunctive,
conditional and
imperative.
Tense formation can be either simple, or compound.
The finite forms are:
  • Indicative
  • *Present which is simple
  • *Present perfect : literally "compound past", formed with an auxiliary verb in the present
  • *Imperfect, simple
  • *Pluperfect : literally "more than perfect", formed with an auxiliary verb in the imperfect
  • *Simple past Conventionally used only in written language or in extremely formal speech.
  • *Past perfect : formed with an auxiliary verb in the past simple. It is somewhat rare.
  • *Simple future
  • *Future perfect : formed with an auxiliary verb in the future simple
  • Subjunctive
  • *Present, simple
  • *Past : formed with an auxiliary verb in the subjunctive present
  • *Imperfect, simple. Somewhat rare.
  • *Pluperfect: formed with an auxiliary verb in the subjunctive imperfect. Somewhat rare.
  • Imperative
  • *Present, simple
  • *Past: formed with an auxiliary verb in the present imperative. Very rarely used in contemporary French.
  • Conditional
  • *Present
  • *Past : formed with an auxiliary verb in the present conditional
  • *Past : formed with an auxiliary verb in the imperfect subjunctive. Rarely used.
The non-finite forms are:
  • Past participle
  • Present participle
  • Gerundive:
Both participles may be used as adjectives in which case they are inflected as adjectives. Used as an adjective the present participle is known as the verbal adjective. There are some cases where a form similar but not identical to the present participle is used for the verbal adjective.

Auxiliary verbs

There are two auxiliary verbs in French: avoir and être, used to conjugate compound tenses according to these rules:
  • Transitive verbs in the active voice are conjugated with the verb avoir.
  • Intransitive verbs are conjugated with either avoir or être.
  • Reflexive verbs are conjugated with être.
  • être is used to form the passive voice. In the passive, it is sometimes necessary to combine conjugated forms of être with avoir as an additional auxiliary verb, e.g. Il a été mangé.
Compound tenses are conjugated with an auxiliary followed by the past participle, ex: j'ai fait, je suis tombé. When être is used, the participle is inflected according to the gender and number of the subject. The participle is inflected with the use of the verb avoir according to the direct object, but only if the direct object precedes the participle, ex:
  • il a marché, elle a marché, nous avons marché
  • il est tombé, elle est tombée, nous sommes tombés, elles sont tombées
  • Il a acheté une voiture. Voilà la voiture qu'il a achetée.
As stand-alone verbs, the conjugation of the two auxiliaries is listed in the appendix at the end of the article.

First group verbs (''-er'' verbs)

French verbs ending in -er, which constitute the largest class, inflect somewhat differently from other verbs. The endings in the present simple singular are written -e, -es and -e, while in the other two groups the endings are more usually -s, -s and -t respectively. This variation is purely orthographic, as these endings are not pronounced in speech. Additional orthographic variations are also implemented to reflect pronunciation; see below for spelling rules.
The first group is demonstrated below with parler.
Present participle: parl-ant
Past participle: parl-é
Auxiliary verb: avoir
Spelling rules:
  • In -cer verbs, the c becomes a ç before endings that start with a or o, to indicate that it is still pronounced /s/ ; similarly, in -ger verbs, the g becomes ge before such endings, to indicate that it is pronounced /ʒ/.
  • In -oyer and -uyer verbs, the y becomes an i before endings that start with a silent e ; in -ayer verbs, this change is optional; both je paye and je paie are accepted as standard. Additionally, the future and conditional forms of envoyer start with enverr- rather than envoyer-; and similarly with renvoyer.
  • In -é.er verbs, the é becomes an è before silent endings, and optionally in the future and conditional tenses.
  • In -e.er verbs other than most -eler and -eter verbs, the e becomes an è before endings that start with a silent e. For example: peler -> je pèle / je pèlerai / je pèlerais.
  • In most -eler and -eter verbs, e is changed to an è before endings that start with a silent e, and l or t are changed to ll or tt. In the rest of these verbs, only one or the other form is considered standard. For example: appeler -> j'appelle / j'appellerai / j'appellerais.
  • The verbal adjective of following verbs is irregular: adhérer - adhérent; coïncider - coïncident; confluer - confluent; affluer - affluent; converger - convergent; déterger - détergent; différer - différent; exceller - excellent; diverger - divergent; négliger - négligent; précéder - précédent; violer - violent; influer - influent; communiquer - communicant; suffoquer - suffocant; provoquer - provocant; naviguer - navigant; déléguer - délégant; fatiguer - fatigant; intriguer - intrigant.
Exceptional contexts:
  • When the first-person singular present tense form of the indicative or subjunctive is found in inversion, authorities require that the final e is changed to either é or è, in order to link the two words : Parlè-je ?,, "Am I speaking?". However, this construction is very rare.
  • When the second-person singular form of the imperative is followed by its object y or en, a final s is added: Parles-en !,, "Talk about it!"
Irregular verbs:
  • envoyer is an irregular in the future and conditional stem - j'enverrai etc., j'enverrais etc. Similarly: renvoyer "resend"
  • aller, though it ends in -er, belongs to the third group.

    Second group verbs (''-ir'' verbs / present participle ending in -issant)

The -ir verbs differ from the -er verbs in the following points:
  • The vowel of the inflections is always -i-, for example -isse in the past subjunctive rather than the -asse of the -er verbs.
  • A few of the singular inflections themselves change, though this is purely orthographic and does not affect the pronunciation: in the present simple and past simple, these are -s, -s, -t rather than -Ø, -s, -Ø.
  • In the present simple, imperfect, the present subjunctive, and the present participle, a suffix -iss- appears between the root and the inflectional endings. In the present simple singular, this suffix has disappeared and the endings are -is, -is, -it.
Present participle: chois-iss-ant
Past participle: chois-i
Auxiliary verb: avoir

Third group verbs

Verbs of the third group have infinitive endings -
  • 1st section: -ir, with the present participle ending in -ant
  • 2nd section: -oir
  • 3rd section: -re
  • aller is included in the third group.
The third group contains all verbs not contained in the first two. While the first and second group have very few irregular members there is a great deal of variation in the third group. Nearly all verbs classified as irregular are included in the third group.
The first source of variation in irregular verbs is stem changes. Stem changes can occur in six places. It is possible to say that the verbs have
seven principal parts, the first being the infinitive itself. No verb has separate stems for all seven parts; instead, rather they tend to "inherit"
the same stem as another part.

The following table shows a conjugation scheme that allows for stem changes. As presented, the table accommodates not only third group verbs but also second group verbs, both having basically the same endings.
A regular second group verb would appear with a stem change in the 1P position and would require a little attention to the 1S stem. The verb choisir is included to represent regular second verbs and haïr is listed as an irregular second group verb. First group verbs would
have different endings in some cases but no stem change.

Past participle: PP
Spelling rules
  • In the indicative present third person singular the -t is regularly dropped when directly following a d or t.
The following table gives the stem changes or principal parts for a number of irregular verbs.
Stems that are irregular in the sense of being unpredictable by the above rules are given in boldface.
Occasionally endings depart from the norm. This is the second source of irregularity.
Such cases are listed in the table following, again with the irregular occurrences highlighted in bold.
* See following table for exceptions.
1 Only in Quebec French.
3 Alternation of "-ai-" and -oi- before consonant or unstressed e, "-ay-" and -oy- before other vowels is automatic in all verbs.
6 The stem is inferred though the usual rule does not apply.
