Mastering -ir and -re Verb Conjugation

Bonjour! Welcome to our third lesson.

Introduction

In our last session, we demystified the most common group of French verbs: the regular -er verbs. You learned the fundamental principle of conjugation: combining a verb's core meaning, its stem (radical), with an ending (terminaison) that corresponds to the subject.

Today, we'll build on that foundation to cover the other two major groups of regular verbs: those ending in -ir and -re. By the end of this lesson, you will be able to distinguish the conjugation patterns for both groups in context. Mastering these three patterns (-er, -ir, and -re) will give you the ability to correctly form a vast number of verbs in the present tense.

1. Regular -ir Verbs: The "Second Group"

Verbs ending in -ir are often called "second group" verbs. They follow a very consistent pattern, but it's important to know that a number of common -ir verbs are irregular and follow different patterns (we'll see these later). For now, let's focus on the regular pattern.

A key feature of these verbs is the appearance of "-iss-" in the plural forms (nous, vous, ils/elles). This is a strong clue that you're dealing with a regular -ir verb.

The following video introduces this group using the verb finir (to finish) as a model.

As you saw, the process is the same as with -er verbs: drop the infinitive ending (-ir) to find the stem, then add the correct ending.

Here is the pattern for regular -ir verbs:

Notice that, like with -er verbs, the singular forms (je, tu, il) are often pronounced identically, even with different spellings. The plural forms are distinct because of the -iss- sound.

2. Regular -re Verbs

The final group of regular verbs are those ending in -re. Technically, these belong to the "third group," which is mostly irregular verbs. However, a significant subset of -re verbs follows a very predictable pattern.

Let's see this pattern in action with the verb entendre (to hear).

The pattern for regular -re verbs is as follows. To get the stem, you drop the -re from the infinitive.

The most unusual part of this pattern is the il/elle/on form, where you add no ending at all—the conjugated form is just the stem.

3. Comparing the Patterns & Practice

You now have the three main regular verb patterns. Let's look at them side-by-side to make the distinctions clear.

Now, let's put your pattern-recognition skills to the test. Try to choose the correct verb form in each sentence. Think about the verb's ending (-er, -ir, or -re) to decide which pattern to use.

1. Les enfants (choisir) un livre.
   a. choisis
   b. choisit
   c. choisissent
2. Nous (attendre) le bus.
   a. attends
   b. attendons
   c. attendent
3. Tu (parler) très bien français !
   a. parle
   b. parles
   c. parlent
4. Je (répondre) à la question.
   a. réponds
   b. répond
   c. répondent

For more hands-on practice, the following resource offers some simple conjugation games. This will help you internalize the patterns by using them repeatedly.

Conclusion

Excellent work today. You have now analyzed the conjugation patterns for all three groups of regular French verbs.

Key Takeaways:

• Regular -ir verbs follow an -is, -is, -it, -issons, -issez, -issent pattern. Their plural forms are easily recognizable by the -iss- infix.
• Regular -re verbs follow an -s, -s, -, -ons, -ez, -ent pattern. The il/elle/on form is unique as it has no special ending.
• The principle remains the same for all groups: find the stem and add the correct ending for the subject.
• Be aware that not all -ir verbs are regular; we will encounter the irregular ones as we go.

In our next lesson, we will step away from regular patterns and focus on the two most important irregular verbs in French: être (to be) and avoir (to have). They are essential for nearly every type of conversation and are the building blocks for future tenses.
