ir_category-present_tense
In French, -ir verbs are another category of regular verbs, and they follow a distinct conjugation pattern. To conjugate an -ir verb in the present tense, you remove the -ir ending from the infinitive, leaving the stem, and then add the appropriate endings: -is, -is, -it, -issons, -issez, -issent. For example, with the verb “finir” (to finish):
je finis (I finish) tu finis (you finish, informal) il/elle finit (he/she finishes) nous finissons (we finish) vous finissez (you finish, formal/plural) ils/elles finissent (they finish)
Most -ir verbs, like choisir (to choose) or réussir (to succeed), follow this regular conjugation pattern, making them easier to learn compared to irregular verbs.
