Conjugating IR Verbs in All Moods and Tenses


Bonjour à tous! As French learners, we understand the importance of verb conjugation in mastering the language. In this blog post, we will delve into the conjugation of IR verbs in all moods and tenses, helping you grasp the nuances and intricacies along the way. So, let’s embark on this journey together and enhance our understanding of the French language!

The Present Tense:

In French, the present tense, known as “le présent,” is used to express actions taking place in the present. To conjugate IR verbs in this tense, we replace the IR ending with the appropriate endings according to the subject:

  • Je finis (I finish)
  • Tu finis (You finish)
  • Il/elle/on finit (He/she/one finishes)
  • Nous finissons (We finish)
  • Vous finissez (You plural/formal finish)
  • Ils/elles finissent (They finish)

The Imperfect Tense:

Also known as “l’imparfait,” this tense describes actions that occurred continuously in the past or used to happen. To conjugate IR verbs, drop the IR ending and add the appropriate endings:

  • Je finissais (I used to finish)
  • Tu finissais (You used to finish)
  • Il/elle/on finissait (He/she/one used to finish)
  • Nous finissions (We used to finish)
  • Vous finissiez (You plural/formal used to finish)
  • Ils/elles finissaient (They used to finish)

The Future Tense:

Expressing actions that will take place in the future, the “le futur” tense requires a particular verb form. For IR verbs, you need to add the appropriate endings to the infinitive form:

  • Je finirai (I will finish)
  • Tu finiras (You will finish)
  • Il/elle/on finira (He/she/one will finish)
  • Nous finirons (We will finish)
  • Vous finirez (You plural/formal will finish)
  • Ils/elles finiront (They will finish)

The Conditional Tense:

The conditional tense, “le conditionnel,” is used to express actions that would occur under specific conditions. For IR verbs, place the appropriate endings after the infinitive form:

  • Je finirais (I would finish)
  • Tu finirais (You would finish)
  • Il/elle/on finirait (He/she/one would finish)
  • Nous finirions (We would finish)
  • Vous finiriez (You plural/formal would finish)
  • Ils/elles finiraient (They would finish)

The Subjunctive Mood:

The subjunctive mood, “le subjonctif,” expresses doubt, possibility, or subjectivity. To conjugate IR verbs in the subjunctive mood, drop the IR ending and add the appropriate endings:

  • Que je finisse (That I finish)
  • Que tu finisses (That you finish)
  • Qu’il/elle/on finisse (That he/she/one finish)
  • Que nous finissions (That we finish)
  • Que vous finissiez (That you plural/formal finish)
  • Qu’ils/elles finissent (That they finish)

The Past Participle:

Lastly, the past participle is essential for forming compound tenses such as the passé composé. For IR verbs, add the ending “i” to the stem of the verb”:

  • Fini (Finished)
  • Finie (Finished-feminine)
  • Finis (Finished-plural/masculine)
  • Finies (Finished-plural/feminine)


Mastering verb conjugation is a crucial aspect of learning French. By understanding and practicing the conjugation of IR verbs in various moods and tenses, you will be well-equipped to express yourself fluently in different situations. Remember, repetition and consistent practice are the keys to success. Bon courage et bonne chance!

Note: This blog post focuses on the conjugation of IR verbs only. However, it’s essential to explore other verb groups (ER and RE) to build a comprehensive understanding of French verb conjugation.
