Regular -ir Verbs (finir, choisir, réussir)

The second group of French verbs are those with infinitives ending in -ir. Regular -ir verbs follow a consistent pattern that includes the characteristic insertion of -iss- in the plural forms. This group is smaller than the -er group but includes many commonly used verbs.

How -ir Verb Conjugation Works

To conjugate a regular -ir verb:

1. Remove the -ir ending to find the stem.
2. Add the present tense endings.

The Endings

Subject	Ending	Example: finir (to finish)
je	-is	je finis
tu	-is	tu finis
il/elle/on	-it	il finit
nous	-issons	nous finissons
vous	-issez	vous finissez
ils/elles	-issent	ils finissent

Key feature: The -iss- in the plural forms (nous, vous, ils/elles) is the hallmark of regular -ir verbs. If a verb ending in -ir does NOT have -iss- in these forms, it is irregular (like partir, dormir, venir).
