Present Tense -IR Verbs: Finir, Choisir, Réussir and the Second Verb Family

Getting Started — Why -IR Verbs Are the Next Step

In Present Tense -ER Verbs, you learned that French verbs fall into three main groups: -ER, -IR, -RE. Now let’s tackle the second group, -IR verbs — like finir (to finish), choisir (to choose), and réussir (to succeed).

A key insight: If you learn “finir”, the same pattern applies to hundreds of verbs like choisir, réussir, and grandir — just swap the stem.

Connection: In -ER verbs, the je/tu/il/ils forms all sounded the same. In -IR verbs, that’s not true — that’s the biggest difference, and it’s covered below.

The -IR Verb Pattern

Infinitive and Stem

All regular -IR verbs share something in common:

Infinitive Stem Explanation
finir fin- Remove ‘-ir’
choisir chois- Remove ‘-ir’
réussir réuss- Remove ‘-ir’
grandir grand- Remove ‘-ir’

The stem rule: Remove the ‘-ir’ from the word, and what’s left is the root — just like -ER verbs. The difference is only in the ending.

Main Conjugation Table (Present Tense)

FINIR (to finish)

Subject Form Pronunciation English
je finis fee-nee I finish
tu finis fee-nee You finish (informal)
il/elle finit fee-nee He/she finishes
nous finissons fee-nee-son We finish
vous finissez fee-nee-say You finish (formal/plural)
ils/elles finissent fee-nees They finish

Important! The ‘-iss-’ Insert

  • je finis / tu finis / il finit — no ‘-iss-’, just stem + -is/-is/-it
  • nous finissons / vous finissez / ils finissent — ‘-iss-’ is always added after the stem

Key insight: In -ER verbs, je/tu/il/ils all sounded the same. That’s not true here — ils finissent’s ‘-iss-’ is clearly audible, while je finis has none. That sound alone tells you singular from plural.

More -IR Verbs

Once you’ve mastered finir, apply the same pattern to these:

Infinitive English Example

Common Mistakes and Fixes

❌ Wrong ✓ Right Explanation
Je finit Je finis ‘je’ always takes -is, not -it (that’s for il/elle)
Nous finis Nous finissons nous takes the -issons ending — don’t forget the ‘-iss-’
Ils finit Ils finissent Subject is plural, so the verb is too: ‘-iss-’ + -ent
Il finissent Il finit Subject is singular (‘il’), so the verb is singular; ‘-iss-’ is only for nous/vous/ils

FAQ

Do all -IR verbs conjugate the same way?

No. The 'regular -IR' group covered in this lesson (finir, choisir, réussir, grandir) is the largest group and uses the '-iss-' pattern. But irregular -IR verbs like partir, sortir, and venir follow a different pattern — those come in a separate lesson.

Where does '-iss-' come from, and when does it appear?

'-iss-' is inserted after the stem only in the nous, vous, and ils/elles forms: nous finissons, vous finissez, ils finissent. It never appears in the je/tu/il forms — those just take stem + -is/-is/-it.

Why do 'Je finis' and 'Il finit' sound different when je/il sounded the same for -ER verbs?

This is exactly what makes -IR verbs distinct: the 's' and 't' are silent, but they're written differently (finis vs finit), and the nous/vous/ils forms audibly add '-iss-' — a clearer spoken distinction than -ER verbs give you.

What's the difference between 'Finir' and 'Je finis'?

'Finir' = infinitive form (to finish). 'Je finis' = conjugated form (I finish). The infinitive is the 'dictionary form' and the conjugated form is what you use in a sentence.
