Main verbs in French convey actions or states. Regular verbs follow predictable patterns based on endings (-er, -ir, -re). Irregular verbs have unique conjugations. Reflexive verbs indicate actions done to oneself. Modal verbs express ability, necessity, or possibility. Phrasal verbs combine with particles. Impersonal verbs lack a specific subject.

Regular -ir verbs are the second-largest category in French. They follow predictable conjugation patterns, typically ending in -is, -is, -it, -issons, -issez, -issent. Examples include “finir” (to finish), “choisir” (to choose), and “partir” (to leave).

Conjugating Regular -ir Verbs 

Here’s a step-by-step guide on conjugating regular -ir French verbs using the example of “finir” (to finish):

Identify the Verb: Choose the regular -ir verb you want to conjugate. For this example, we’ll use “finir” (to finish).

Remove the Infinitive Ending: Remove the infinitive ending “-ir” from the verb stem. This leaves you with the verb stem or root. For “finir,” removing “-ir” leaves the root “fin-“.

Add the Conjugation Endings: Once you have the verb stem, you can add the appropriate endings for each subject pronoun. These endings are specific to each tense and indicate who is performing the action. For regular -ir verbs in the present tense, the endings are as follows:

  • Je (I): -is
  • Tu (You, singular informal): -is
  • Il/Elle/On (He/She/We): -it
  • Nous (We): -issons
  • Vous (You, plural or singular formal): -issez
  • Ils/Elles (They): -issent

Conjugate the Verb: Attach the appropriate ending to the verb stem for each subject pronoun. For “finir” in the present tense:

  • Je finis (I finish)
  • Tu finis (You finish)
  • Il/Elle/On finit (He/She finishes)
  • Nous finissons (We finish)
  • Vous finissez (You finish)
  • Ils/Elles finissent (They finish)

By following these steps, you can easily conjugate regular -ir verbs in French by removing the infinitive ending to find the appropriate conjugation endings.

Conjugate the Verb with Examples:

  • Je finis mon travail. (I finish my work.)
  • Tu finis tes devoirs. (You finish your homework.)
  • Il/Elle/On finit sa lecture. (He/She finishes his/her reading.)
  • Nous finissons notre repas. (We finish our meal.)
  • Vous finissez votre conversation. (You finish your conversation.)
  • Ils/Elles finissent leur jeu. (They finish their game.)

Review and Practice: 

Review the conjugations for each subject pronoun and practice using them in sentences to reinforce your understanding.

Using this step-by-step guide, you can conjugate any regular -ir verb in French.

In French, when conjugating regular verbs, you typically remove the infinitive ending (-er, -ir, -re) to find the appropriate conjugation endings.

Hence, to summarize, to conjugate regular -ir verbs like “finir” in the present tense, remove the “-ir” ending to get the stem “fin-“, then add the appropriate endings for each subject pronoun: -is, -is, -it, -issons, -issez, -issent.

Frequently Asked Questions

1. How do you know if an IR verb is regular or irregular?

In French, determining whether an -ir verb is regular or irregular depends on its conjugation pattern.

Regular -ir Verbs:

  • Follow predictable conjugation patterns without significant changes in the verb stem.
  • Conjugate according to standard rules for each tense and mood.

Irregular -ir Verbs:

  • Deviate from standard conjugation patterns.
  • Display irregularities in stem changes, endings, or both.
  • Often require memorization of their unique conjugations.

To identify whether an -ir verb is regular or irregular, it’s essential to study its conjugation and observe any irregularities or deviations from regular patterns.

2. How many regular IR verbs are there in French?

In French, there is no fixed number of regular -ir verbs as they can be formed by adding the “-ir” ending to various verb stems. However, there are hundreds of regular -ir verbs in French, making them a significant category of verbs. These regular verbs follow predictable conjugation patterns and are essential for everyday communication.

3. What are the 3 regular verb endings? 

The three regular verb endings in French are:

  1. -er: This ending is characteristic of infinitive verbs in the first group (e.g., “parler” – to speak, “manger” – to eat).
  2. -ir: This ending is typical of infinitive verbs in the second group (e.g., “finir” – to finish, “choisir” – to choose).
  3. -re: This ending is common among infinitive verbs in the third group (e.g., “vendre” – to sell, “attendre” – to wait).

4. Where does the verb IR come from? 

The verb “ir” comes from Latin, specifically from the Latin verb “ire,” which means “to go.” Over time, as Latin evolved into French, “ire” transformed into “aller” (to go) in modern French. However, “ir” is still used as an infinitive ending for many verbs in the second conjugation group in French, such as “finir” (to finish) and “choisir” (to choose).
