Mastering Irregular French Subjunctive Conjugations

Updated on 2024-08-28

French learners often find the subjunctive mood challenging, especially when it comes to irregular verbs.

This guide will help you navigate the complexities of irregular French subjunctive conjugations, focusing on stem-changing verbs and highly irregular verbs.

Stem-Changing Verbs

Stem-changing verbs in the subjunctive follow a two-stem pattern:

  1. For singular and third person plural forms, use the stem from the present tense third person plural (ils) conjugation.
  2. For first and second person plural forms, use the stem from the present tense first person plural (nous) conjugation.

Examples of Stem-Changing Verbs

Let's look at three common stem-changing verbs: lever (to raise), jeter (to throw), and essayer (to try).

| Person | Lever | Jeter | Essayer | |-------------|-----------|-----------|------------| | je | lève | jette | essaie | | tu | lèves | jettes | essaies | | il/elle/on | lève | jette | essaie | | nous | levions | jetions | essayions | | vous | leviez | jetiez | essayiez | | ils/elles | lèvent | jettent | essaient |

Very Irregular Verbs

Some very irregular verbs follow the same two-stem pattern as stem-changing verbs. Here are examples with devoir (to have to), prendre (to take), and tenir (to hold):

| Person | Devoir | Prendre | Tenir | |-------------|-----------|-----------|------------| | je | doive | prenne | tienne | | tu | doives | prennes | tiennes | | il/elle/on | doive | prenne | tienne | | nous | devions | prenions | tenions | | vous | deviez | preniez | teniez | | ils/elles | doivent | prennent | tiennent |

Extremely Irregular Verbs

Seven French verbs are considered extremely irregular in the subjunctive. They have unique stems but use standard subjunctive endings.

Single-Stem Verbs

  • faire (to do/make): fass-
  • pouvoir (to be able to): puiss-
  • savoir (to know): sach-

Two-Stem Verbs

  • aller (to go): aill- / all-
  • valoir (to be worth): vaill- / val-
  • vouloir (to want): veuill- / voul-

Example conjugations:

| Person | Faire | Pouvoir | Aller | |-------------|-----------|-----------|------------| | je | fasse | puisse | aille | | tu | fasses | puisses | ailles | | il/elle/on | fasse | puisse | aille | | nous | fassions | puissions | allions | | vous | fassiez | puissiez | alliez | | ils/elles | fassent | puissent | aillent |

Note: The impersonal verb falloir (to be necessary) has only one subjunctive form: qu'il faille.

Ridiculously Irregular Verbs

The verbs avoir (to have) and être (to be) are the most irregular in French, including in the subjunctive:

| Person | Avoir | Être | |-------------|-----------|-----------| | je | aie | sois | | tu | aies | sois | | il/elle/on | ait | soit | | nous | ayons | soyons | | vous | ayez | soyez | | ils/elles | aient | soient |

Practice Makes Perfect

To truly master irregular French subjunctive conjugations, consistent practice is key. Try creating sentences using these verbs in various contexts. For example:

  1. Il faut que tu ailles au marché. (You need to go to the market.)
  2. Je doute qu'il puisse finir à temps. (I doubt he can finish on time.)
  3. Il est important que nous soyons patients. (It's important that we be patient.)

By understanding these patterns and practicing regularly, you'll soon find yourself using the French subjunctive with confidence, even with irregular verbs.
